    Full Text Available Propolis contains resinous substances collected by honey bees from various plant sources and has been used as a traditional folk medicine since ca 300 BC. Nowadays, the use of evidence-based complementary and alternative medicine (CAM is increasing rapidly and so is the use of propolis in order to treat or support the treatment of various diseases. Much attention has been focused on propolis from Populus sp. (Salicaceae and Baccharis dracunculifolia (Asteracea, but scientific information about the numerous other types of propolis is still sparse. We gathered six samples of red propolis in five states of Northeastern Brazil. The beehives were located near woody perennial shrubs along the sea and river shores. The bees were observed to collect red resinous exudates on Dalbergia ecastophyllum (L Taub. (Leguminosae to make propolis. The flavonoids of propolis and red resinous exudates were investigated using reversed-phase high-performance liquid chromatography and reversed-phase high-performance thin-layer chromatography. We conclude that the botanical origin of the reddish propolis is D. ecastophyllum. In areas where this source (D. ecastophyllum was scarce or missing, bees were collecting resinous material from other plants. Propolis, which contained the chemical constituents from the main botanical origin, showed higher antimicrobial activity.

    Full Text Available The terpenoid compositions of the Late Cretaceous Xixia amber from Central China and the middle Miocene Zhangpu amber from Southeast China were analyzed by gas chromatography-mass spectrometry (GC-MS to elucidate their botanical origins. The Xixia amber is characterized by sesquiterpenoids, abietane and phyllocladane type diterpenoids, but lacks phenolic abietanes and labdane derivatives. The molecular compositions indicate that the Xixia amber is most likely contributed by the conifer family Araucariaceae, which is today distributed primarily in the Southern Hemisphere, but widely occurred in the Northern Hemisphere during the Mesozoic according to paleobotanical evidence. The middle Miocene Zhangpu amber is characterized by amyrin and amyrone-based triterpenoids and cadalene-based sesquiterpenoids. It is considered derived from the tropical angiosperm family Dipterocarpaceae based on these compounds and the co-occurring fossil winged fruits of the family in Zhangpu. This provides new evidence for the occurrence of a dipterocarp forest in the middle Miocene of Southeast China. It is the first detailed biomarker study for amber from East Asia.

    In order to understand the temporal changes of botanical composition in grassland ecosystem, and to clarify the relation between these changes and environmental impacts, such as climatic factors and artificial disturbance, a grazing trail was carried out during a 21-year period from 1974 at a sown grassland of the National Grassland Research Institute, located in Nishinasuno, the central area of Japan. The data sets of biomass for each mouth(from April to November)of the 21-year period were analyzed in this paper. The botanical composition of aboveground biomass varied greatly witl both season and year. The biomass ratio of improved herbage species to invaded native plants gradually decreased each year. This may have been owing to meteorological factors, such as Iow air-temperature in winter, dry and hot summers, grassland management(including grazing intensity and fertilizer application), and inter-specific competition between native and introduced herbage plants.

    Full Text Available Breeding for enhanced nutritional quality is need of the hour. India not only needs increased quantity of food to feed the growing population but also quality food to mitigate hidden hunger. Oil is the major energy source of the Indian diet. Chemical composition of oil decides its edible nature. Even in edible oil fatty acid composition in general and ratio of oleic acid to linoleic acid of the oil plays major role in deciding its quality. In India, availability of breeding line to improve groundnut oil quality is limited. Screening of different botanical group may give some idea about choice of material for further crop improvement program. In present study botanical group hypogaea, found to have higher amount of oleic acid and fastigiata group recorded high protein and oil content. Growing season also matters in the expression of different fatty acid. Rainy season is found to have better for the better expression of all studied traits.

    Full Text Available This study was carried out to evaluate the dynamics of sward condition and botanical composition of a mixed pasture of marandugrass (Brachiaria brizantha cv. Marandu, forage peanut (Arachis pintoi cv. Mandobi and tropical kudzu (Pueraria phaseoloides, rotationally stocked at four daily forage allowance levels (6.6, 10.3, 14.3 and 17.9% of live weight. Sward condition was characterized in each stocking cycle by measuring pre- and post-grazing sward height, forage mass and percentage of bare ground. Botanical composition (grass, forage peanut, tropical kudzu and weeds was evaluated before each stocking period. Swards under smaller forage allowances presented lower height, forage mass and ground cover. This condition favored the growth of forage peanut, which constituted 21.1, 15.2, 8.4 and 3.8% of forage mass in the last quarter of the experimental period, from the lowest to the highest forage allowance, respectively. Tropical kudzu was sensitive to all forage allowance levels and its percentage in the botanical composition was strongly reduced along the experimental period, especially during the dry season (July to September. Forage peanut cv. Mandobi and marandugrass form a more balanced mixture when pre-grazing sward height is maintained shorter than 45 cm. Tropical kudzu is intolerant to intensive grazing management systems when associated to marandugrass.

    Full Text Available This research was planned and conducted on floodplain and steppe areas of a natural rangeland in Karamurat Village, Malkara District, Tekirdağ Province in 2005-2006 period. The purpose of this study, effects of fertilizer application on forage production and botanical composition of Floodplain and steppe rangelands of Tekirdağ. The yields of forage and dry matter vegetation was determined by cutting in blooming time and botanical composition and canopy cover via transect and point-frame measurements. In the 2005 and 2006 , in Autumn, 4 kg/da N and P and 3.6 kg/da N and P, in Spring 4.2 and 5 kg/da N was applied on the rangeland. The experimental area was 1940da. 1m2cages were placed for measurements on unfertilized areas. The rangeland was under control in both years (2005-2006. On barren and basement area of natural rangelands, fertilizing gave rise to most amount of fresh forage and dry hay in 2005 and 2006. Fertilization gave rise to significant yields in forage and dry matter in both floodplain and steppe areas in the study period. According to the averages of fresh forage and dry weights in 2005 and 2006, the estimated rangeland yields were in both fertilized and unfertilized the floodplain areas 2095.0 kg/da and 1150.0 kg/da, 620.0 kg/da and 349.0 kg/da, respectively. The yields were in fresh forage weight and dry weight in both fertilized and unfertilized of the dryland areas as 1665.0 kg/da and 845.0 kg/da, 342.0 kg/da and 240.0 kg /da in the cages, respectively. Fertilizing primarily effects botanical composition and canopy cover of a rangeland. With fertilizing, botanical composition was determined to increase rates of Fabaceae and Poaceae and reduce the rates of other families in transect and point-frame measurements in the fertilized area. The results indicated that plant-covered area measurement values on fertilized rangeland were 85.6% and 95.8% on average by transect measurement method the values on fertilized areas were 88

    Fossil resins from the Cretaceous sediments of Meghalaya, India and Kachin, Myanmar (Burma) were analysed using Curie point pyrolysis-gas chromatography-mass spectrometry and thermochemolysis gas chromatography-mass spectrometry to help elucidate their botanical source. The major pyrolysis products and methyl-esterified thermochemolysis products of both the resins were abietane and labdane type diterpenoids with minor amount of sesquiterpenoids. The thermochemolysis products also included methyl-16,17-dinor callitrisate, methyl-16,17-dinor dehydroabietate and methyl-8-pimaren-18-oate - the latter two from just the Myanmarese resin. The exclusive presence of both labdane and abietane diterpenoids and the lack of phenolic terpenoids may suggest that the studied Cretaceous resins were derived from Pinaceae (pine family) conifers.

    Full Text Available This study was conducted at the apiary of the Agricultural and Veterinary Training and Research Station, King Faisal University, Al-Ahsa, Saudi Arabia. The purpose was to study the relationship between the botanical origin and chemical composition of bee-collected pollen. The amount of mineral elements present in bee-collected pollen was also studied. The composition of pollen loads showed the maximum contents of dry matter, ash, glucose, fructose, magnesium (Mg, phosphorus (P, and manganese (Mn for the date palm; the maximum contents of protein, calcium (Ca, and zinc (Zn for alfalfa; the maximum contents of fiber, and copper (Cu for the sunflower; the maximum contents of the lipids and iron (Fe for summer squash; and the maximum contents of sodium (Na, and potassium (K for rape. Calcium was found to be correlated in a significantly (p<0.01 positive way with K, Na, Mg, P, Mn, and Zn. Copper, though, was correlated in a significantly (p<0.01 negative way with Ca, Mg, P, Mn, and Zn. The high levels of protein, ash, glucose, and fructose, and low lipid content found in bee-pollen from the date palm and from alfalfa, mean that pollen from the date palm and from alfalfa make an excellent food supplement. It was concluded, that the chemical composition of beecollected pollen can be correlated with the plant species from which pollen was collected.

    Full Text Available Species Composition and Structure of the Communities of Plant-Parasitic and Free-Living Soil Nematodes in the Greenhouses of Botanical Gardens of Ukraine. Gubin, A. I., Sigareva, D. D. — In greenhouses of botanical gardens of Ukraine 81 species of nematodes were found. The richest by the number of species was Tylenchida order that was presented by 25 species (31 % of species composition. The dominant group of nematodes was plant-parasitic (most frequent was Rotylenchus robustus (de Man, 1876 Filipjev, 1936 and Meloidogyne incognita (Kofoid et White, 1919 Chitwood, 1949. The group of saprobiotic nematodes, which was presented by 52 species (64 %, appeared to be the richest by the number of species. It is shown, that formation of nematode communities in greenhouses of botanical gardens was caused by the interaction of many related factors, crucial of which is the composition of plant collections. The structure of communities is quite constant and almost independent of the quantity of nematodes species. Plant-parasitic species dominate by the number and frequency of detection, and represent a kind of a core of nematode communities.

    Background. Obesity and its comorbidities continue to challenge the world at an alarming rate. Although the long term solution lies on lifestyle changes in the form of dieting and exercising, drug, medical food, or dietary supplement interventions are required for those who are already obese. Here we describe a standardized blend composed of extracts from three medicinal plants: Morus alba, Yerba mate, and Magnolia officinalis for appetite suppression and metabolic disorders management. Method. Extracts were standardized to yield a composition designated as UP601. Appetite suppression activity was tested in acute feed intake rat model. Efficacy was evaluated in C57BL/6J mouse models treated with oral doses of 1.3 g/kg/day for 7 weeks. Orlistat at 40 mg/kg/day was used as a positive control. Body compositions of mice were assessed using a dual energy X-ray absorptiometry (DEXA). ELISA was done for insulin, leptin, and ghrelin level quantitation. Nonalcoholic steatohepatitis (NASH) scoring was conducted. Results. Marked acute hypophagia with 81.8, 75.3, 43.9, and 30.9% reductions in food intake at 2, 4, 6, and 24 hours were observed for UP601. Decreases in body weight gain (21.5% compared to the HFD at weeks 7 and 8.2% compared to baseline) and calorie intake (40.5% for the first week) were observed. 75.9% and 46.8% reductions in insulin and leptin, respectively, 4.2-fold increase in ghrelin level, and reductions of 18.6% in cholesterol and 59% in low-density lipoprotein were documented. A percentage body fat of 18.9%, 47.8%, 46.1%, and 30.4% was found for mice treated with normal control, HFD, Orlistat, and UP601, respectively. 59.3% less mesenteric fat pad and improved NASH scores were observed for UP601. Conclusion. UP601, a standardized botanical composition from Morus alba, Yerba mate, and Magnolia officinalis could be used as a natural alternative for appetite suppression, maintaining healthy body weight and metabolism management.

    Full Text Available Stingless bees in Brazil are indigenous and found all over the country. Bee pollen is used for its nutritional value in the human diet. It is made up of natural flower pollen mixed with nectar and bee secretions. In order to evaluate the chemical composition, free radical scavenging activity, and botanical origin, sample of pollen loads from stingless bee, Melipona rufiventris (Uruçu amarela was studied. The EtOAc extract of pollen of Melipona rufiventris yielded the following compounds: p-hydroxycinnamic acid, dihydroquercetin, isorhamnetin, isorhamnetin3-O-(6"-O-E-p-coumaroyl-β-D-glucopyranoside, luteolin, and quercetin. This is the first report of the isolation of isorhamnetin3-O-(6"O-E-p-coumaroylβ-D-glucopyranoside from pollen. The free radicalscavenging activities of different solvent extracts of pollen were determined using DPPH assay. This activity decreases in the order: EtOAc>EtOH>Hexane extract. It appears that the EtOAc extract of the pollen is a good scavenger of active oxygen species. The botanical evaluation of pollen loads showed the composition by two pollen types, with the dominant type (97.3% being Scopariadulcis (L. (Scrophulariaceae and the minor one Senna obtusifolia (L. Irwin & Barneby (Fabaceae. This suggests a specific foraging behavior in Melipona rufiventris bees, even in an environment with such a rich botanical diversity as the Northeastern Brazil.As abelhas sem ferrão são espécies indígenas encontradas em todo o Brasil. Seu pólen é utilizado devido ao seu valor nutricional na dieta humana. É produzido a partir de pólen floral misturado com néctar e líquidos secretados pelas abelhas.

    Full Text Available Background: Osteoarthritis (OA is a chronic debilitating degenerative joint disease characterized by cartilage degradation and synovial inflammation exhibited by clinical symptoms such as joint swelling, synovitis, and inflammatory pain. Present day pain relief therapeutics heavily relies on the use of prescription and over the counter nonsteroidal anti-inflammatory drugs as the first line of defense where their long-term usage causes detrimental gastrointestinal and cardiovascular-related side-effects. As a result, the need for evidence based safer and efficacious alternatives from natural sources to overcome the most prominent and disabling symptoms of arthritis is a necessity. Materials and Methods: Describe the anti-inflammatory and analgesic effect of UP3005, a composition that contains a standardized blend of two extracts from the leaf of Uncaria gambir and the root bark of Morus alba in carrageenan-induced rat paw edema, abdominal constriction (writhing′s and ear swelling assays in mouse with oral dose ranges of 100-400 mg/kg. Results: In vivo, statistically significant improvement in pain resistance, and suppression of paw edema and ear thickness in animals treated with UP3005 were observed compared with vehicle-treated diseased rats and mice. Ibuprofen was used a reference compound in all the studies. In vitro, enzymatic inhibition activities of UP3005 were determined with IC50 values of 12.4 μg/ml, 39.8 μg/ml and 13.6 μg/ml in cyclooxygenase-2 (COX-1, COX-2 and lipoxygenase (5-LOX enzyme activity assay, respectively. Conclusions: These data suggest that UP3005, analgesic and anti-inflammatory agent of botanical origin with balanced dual COX-LOX inhibition activity, could potentially be used for symptom management of OA.

    Isman, Murray B

    2015-12-01

    Botanical insecticides continue to be a subject of keen interest among the international research community, reflected in the steady growth in scientific publications devoted to the subject. Until very recently though, the translation of that theory to practice, i.e. the commercialisation and adoption of new botanical insecticides in the marketplace, has seriously lagged behind. Strict regulatory regimes, long the bane of small pesticide producers, are beginning to relax some of the data requirements for 'low-risk' pesticide products, facilitating movement of more botanicals into the commercial arena. In this paper I discuss some of the jurisdictions where botanicals are increasingly finding favour, some of the newer botanical insecticides in the plant and animal health arsenal and some of the specific sectors where botanicals are most likely to compete effectively with other types of insecticidal product.

    2012-01-01

    Full Text Available Prevention of food losses during postharvest storage is of paramount economic importance. Integrated pest management is now a widely accepted strategy in pest control including postharvest infestation control which involves the use of chemical (contact/residual insecticides along with fumigants. The use of synthetic chemical insecticides is either not permitted or used restrictively because of the residue problem and health risks to consumers. In view of the above, there is a need for plants that may provide potential alternatives to the currently used insect control agents as they constitute a rich source of bioactive molecules. Available literature indicates that plant could be source for new insecticides. Therefore, there is a great potential for a plant-derived insecticidal compounds. This paper focuses on the current state of the botanical insecticides as grain protectants and its mode of action.

    Natural substances are generally preferred over chemical ones and are generally seen as healthy. The increasing demand for natural ingredients, improving health and appearance, is also attracting beverages as the fastest growing segment on the functional food market. Functional beverages are launched as fortified water, tea, diary or juices claiming overall nutrition, energy, anti-aging or relaxing effects. The substitution of so called superfruits, such as berries, grapes, or pomegranate delivers an effective range of beneficial compounds, including vitamins, fatty acids, minerals, and anti-oxidants. In this context, new exotic and African fruits could be useful sources in the near future. Teas and green botanicals, such as algae or aloe vera are also rich in effective bioactives and have been used traditionally. The botanical kingdom offers endless possibilities. PMID:19168002

    Full Text Available The chemical composition of the forage obtained from permanent pastures is determined, in its turn, by the floristic structure consisted of species belonging to various botanic families. Each botanic species presents a specific chemical content and a certain contribution to the balancing of forage’s nutritional value. The chemical analyses performed, at species level, revealed the importance of the “diverse” species, which, with their content in mineral elements, may influence animals’ capacity of production and reproduction. Some of the species, considered to be weeds within the permanent pastures’ floristic composition, presented high crude protein content values: Achillea millefolium with 24.22%, Taraxacum officinale 24.06%, Urtica dioica with 32.46%, Plantago major with 17.04%, etc.

    2010-01-01

    The biological mechanism of action for any botanical extract is a necessary part of discovery to determine pharmacological use and safety. Interestingly, many activities that are governed by endogenous compounds are not fully understood making the characterization of mechanisms elusive. For example, phytoestrogens are being consumed for menopausal symptoms while the biological action of estradiol are still being investigated. Therefore, long term efficacy and safety issues are a challenge in the field. As new activities are associated with new biological pathways, an important component of therapeutic discovery will need to be the re-evaluation of negative or less active natural products to determine their relative use as medicines.

  15. Ionic profile of honey as a potential indicator of botanical origin and global environmental pollution

    International Nuclear Information System (INIS)

    Aim of this study was to determine by Ion Chromatography ions (Na+, Ca++, Mg++, NH4+, Cl−, Br−, SO42−, NO3−, PO43−) in honeys (honeydew and floral nectar honeys) from different Italian Regions and from countries of the Western Balkan area. The compositional data were processed by multivariate analysis (PCA and HCA). Arboreal honeydew honeys from the Western Balkans had higher concentrations (from two to three times) of some environmental pollutants (Br−, SO42− and PO43− contents), due to industrial and agricultural activities, than those from Italian regions. The cationic profiles were very similar in both groups. Multivariate analysis indicated a clear difference between nectar honeys and arboreal/honeydew honeys (recognition of the botanical origin). These findings point to the potential of ionic constituents of honey as indicators of environmental pollution, botanical origin and authenticity. -- Highlights: •Analysis by IC of honeys from two areas with different environmental pollution (Italy and Balkans). •Chemometric techniques such as PCA and HCA used. •In Balkans area higher Br−, SO42− and PO43− due to industrial and agricultural activities. •Discrimination of honey botanical origin and authenticity on the base of IC data. •Honey ionic profiles as indicators of environmental pollution and botanical origin. -- Capsule: Ionic profiles of honey could be potential indicators of environmental pollution (industrial and agricultural), botanical origin and authenticity

    The use of botanical products and vitamins in skin care creams and sunscreens is prevalent. Herein we conduct an evaluation of sunscreens to quantitatively assess how often sunscreens incorporate botanically derived products and vitamins. The most commonly used botanicals products and vitamins are identified and stratified based on the sunscreen sun protection factor (SPF). The overall prevalence for the use of botanical agents and vitamins was 62% and 79%, respectively. Aloe vera and licorice root extracts were the most common botanical agents used in sunscreens. Retinyl palmitate was the most common vitamin derivative utilized in sunscreens. The prices of sunscreens significantly increased when more than one botanical product was added. Botanical products and vitamins are widely utilized in sunscreens and more research is needed to assess how their inclusion may enhance or alter the function of sunscreens. PMID:26632925

    The discovery, development and marketing of food supplements, nutraceuticals and related products are currently the fastest growing segments of the food industry. Functional foods can be considered part or borderline to these products and may be defined as foods or food ingredients that have additional health or physiological benefits over and above the normal nutritional value they provide. This trend is driven by several factors, mainly due to the current consumer perceptions: the first and dominant being 'Natural is good', and other secondary, such as the increasing cost of many pharmaceuticals and their negative secondary effects, the insistent marketing campaign, the increasing perception of the need of a healthy diet and its importance in the health and homeostasis organism conditions. However, the central point is that nutraceuticals, botanicals and other herbal remedies, including the entry of new functional foods, are important because of their acceptance as the novel and modern forms to benefit of natural substances. Due to the rapid expansion in this area, the development of several aspects is considered as it could influence the future of the market of these products negatively: an imbalance existing between the increasing number of claims and products on the one hand, the development of policies to regulate their application and safety on the other, rapid and valuable controls to check the composition, including the plant extracts or adulteration to improve efficacy, like the presence of synthetic drugs. It is interesting to see that, from the negative factors reported by the market analysts, a change in consumers preferences is absent. The functional properties of many plant extracts, in particular, are being investigated for potential use as novel nutraceuticals and functional foods. Although the availability of scientific data is rapidly improving, the central aspect concerns the validation of these products. The first step of this crucial aspect is

  2. Ethno-botanical studies from northern Pakistan

    International Nuclear Information System (INIS)

    In this research paper efforts have been made to document the ethno-botanical knowledge of important plant species found in Northern Pakistan. It includes Thandiani, Galiat, Kaghan, Swat, Buner, Dir, Chitral and Northern Areas of Pakistan. The area has many climatic and vegetation zones or biomes. Locals residing in mountainous areas belonging to various ethnic groups are traditionally utilizing plants over many generations; these ethnic groups have their distinct life style, belief, traditions and cultural heritage. Plant collection and data regarding traditional uses in various areas of Northern Pakistan has been done periodically in different flowering /fruiting seasons. Locals of old age belonging to various ethnic groups were personally interviewed for establishing uses of plants. Photography is done for easy identification and habitat recognition. Collected plant specimens and seeds were preserved. Plant species were dried, mounted, identified and authenticated. Seventy six species were known to have traditional and ethno botanical uses. Plants have been utilized for many generations. Ethnic groups have distinct life style and have different economic uses for these plants. Due to unsustainable exploitation of natural habitats scarcity of drug plants has occurred. As consequence some species are depleting and may become extinct in near future, e. g. Morchella esculenta, Colchicum lueteum and Viola serpens are just a few of these. Although some sporadic information is available about the flora of this region but very little documented record of the ethno-botanically important plants has been established. It is expected that this research paper will be beneficial for students, researchers, farmers, foresters and general public. On the basis of data obtained it is concluded that ethno-botanical Flora of Northern Pakistan is quite rich and is diverse, due to the difference in altitude, climate and other topographic conditions.

Sward condition was characterized in each grazing cycle in terms of the pre and post-grazing sward height, forage mass and percentage of bare ground. Botanical composition (grass, legume and weeds was evaluated before each grazing period. Sward height and forage mass increased linearly with increasing herbage allowance (HA levels, and higher values were observed during the rainy season. Percentage of bare ground increased primarily at the lowest HA level. Percentage of forage peanut increased throughout the experimental period, primarily in the barest and shortest swards, under the lowest HA level. In the last quarter of 2003 the legume constituted 23.5, 10.6 and 6.4% of the pasture forage mass, respectively, from the lowest to the highest HA level. These results suggest that forage peanut can be successfully associated with massaigrass, as long as the pre-grazing sward height is maintained shorter than 65-70 cm, which will prevent excessive shading to the legume.Este estudo foi realizado com o objetivo de avaliar a dinâmica e a composição botânica de uma pastagem consorciada de capim-massai (Panicum maximum x P. infestum, cv.

    The continuously increasing demands on botanic gardens during the last few decades have led to a huge in increase administration and an urgent need for additional specialized personnel, especially botanists, teachers, database specialists and administrative staff. Instead of meeting these requirements, many botanic gardens are faceing a severe decrease in funding and personnel. Larger gardens provide the opportunity to distribute several tasks to different employees, whereas small gardens are short staffed and often nn by a single curator who has to fulfill all functions. In order to meet actual demands more easily, the Austrian botanic gardens are linked nationally via an active workgroup.This network not only allows the distribution of information but also facilitates the sharing of duties. A listserver speeds up the communication and correspondence within the workgroup, collection priorities and projects (e. g., GSPC) are coordinated, seedbanking becomes decentralized, printedmatters are shared and distributed, etc. Small gardens with only few employees can participate in projects by taking on small-ideally using with their special resources-in order not to fall behind. In addition, there is also an urgent need for international networking by means of plant and seed exchange (Index Semihum), BGCI membership, discussion groups, personal contacts and projects. Mission statements,special marketing strategies for public relations, integrating projects of other workgroup members and adapted public awareness programs are important to focus attention to small gardens and to help them keep alive.

  12. William Keit and the Durban Botanic Garden

    Full Text Available William Keit was born in Saxony in 1841 and in early life travelled across Europe working in many famous nurseries and gardens. In 1872 on the recommendation of the director of Kew Gardens, Keit emigrated to Natal to become curator of the Durban Botanic Garden. So dilapidated was this garden that Keit was faced with the task of virtually re-establishing it.Though he was largely successful in this endeavour, as he was in fortifying the link between Natal and Kew, Keit could not solve the problems of a severe drought,a labour shortage and a scarcity of funds. In 1881 he resigned his position leaving a solid foundation on which the renowned botanist, John Medley Wood was to build. Keit in later Ufe ran a successful nursery in Durban and for 30 years was curator of the Parks and Gardens Department,in which capacity he did more than anyone else to beautify Durban.

    Full Text Available The growing popularity of botanical dietary supplements (BDS has been accompanied by concerns regarding the quality of commercial products. Health care providers, in particular, have an interest in knowing about product quality, in view of the issues related to herb-drug interactions and potential side effects. This study assessed whether commercial formulations of saw palmetto, kava kava, echinacea, ginseng and St. John's wort had consistent labeling and whether quantities of marker compounds agreed with the amounts stated on the label. We purchased six bottles each of two lots of supplements from nine manufacturers and analyzed the contents using established commercial methodologies at an independent laboratory. Product labels were found to vary in the information provided, such as serving recommendations and information about the herb itself (species, part of the plant, marker compound, etc. With regard to marker compound content, little variability was observed between different lots of the same brand, while the content did vary widely between brands (e.g. total phenolic compounds in Echinacea ranged from 3.9–15.3 mg per serving; total ginsenosides in ginseng ranged from 5.3–18.2 mg per serving. Further, the amounts recommended for daily use also differed between brands, increasing the potential range of a consumer's daily dose. Echinacea and ginseng were the most variable, while St. John's wort and saw palmetto were the least variable. This study highlights some of the key issues in the botanical supplement market, including the importance of standardized manufacturing practices and reliable labeling information. In addition, health care providers should keep themselves informed regarding product quality in order to be able to appropriately advise patients utilizing both conventional and herbal medicines.

    Full Text Available Osteoarthritis (OA is a multifactorial disease primarily noted by cartilage degradation in association with inflammation that causes significant morbidity, joint pain, stiffness, and limited mobility. Present-day management of OA is inadequate due to the lack of principal therapies proven to be effective in hindering disease progression where symptomatic therapy focused approach masks the actual etiology leading to irreversible damage. Here, we describe the effect of UP3005, a composition containing a proprietary blend of two standardized extracts from the leaf of Uncaria gambir and the root bark of Morus alba, in maintaining joint structural integrity and alleviating OA associated symptoms in monosodium-iodoacetate- (MIA- induced rat OA disease model. Pain sensitivity, micro-CT, histopathology, and glycosaminoglycans (GAGs level analysis were conducted. Diclofenac at 10 mg/kg was used as a reference compound. UP3005 resulted in almost a complete inhibition in proteoglycans degradation, reductions of 16.6% (week 4, 40.5% (week 5, and 22.0% (week 6 in pain sensitivity, statistically significant improvements in articular cartilage matrix integrity, minimal visual subchondral bone damage, and statistically significant increase in bone mineral density when compared to the vehicle control with MIA. Therefore, UP3005 could potentially be considered as an alternative therapy from natural sources for the treatment of OA and/or its associated symptoms.

    2010-01-01

    Botanical extracts and single compounds are increasingly used in cosmetics but also in over-the-counter drugs and food supplements. The focus of the present review is on controlled clinical trials with botanicals in the treatment of acne, inflammatory skin diseases, skin infections, UV-induced skin damage, skin cancer, alopecia, vitiligo, and wounds. Studies with botanical cosmetics and drugs are discussed, as well as studies with botanical food supplements. Experimental research on botanicals was considered to a limited extent when it seemed promising for clinical use in the near future. In acne therapy, Mahonia, tea tree oil, and Saccharomyces may have the potential to become standard treatments. Mahonia, Hypericum, Glycyrrhiza and some traditional Chinese medicines appear promising for atopic dermatitis. Some plant-derived substances like dithranol and methoxsalen (8-methoxypsoralen) [in combination with UVA] are already accepted as standard treatments in psoriasis; Mahonia and Capsicum (capsaicin) are the next candidates suggested by present evidence. Oral administration and topical application of antioxidant plant extracts (green and black tea, carotenoids, coffee, and many flavonoids from fruits and vegetables) can protect skin from UV-induced erythema, early aging, and irradiation-induced cancer. Hair loss and vitiligo are also traditional fields of application for botanicals. According to the number and quality of clinical trials with botanicals, the best evidence exists for the treatment of inflammatory skin diseases, i.e. atopic dermatitis and psoriasis. However, many more controlled clinical studies are needed to determine the efficacy and risks of plant-derived products in dermatology. Safety aspects, especially related to sensitization and photodermatitis, have to be taken into account. Therefore, clinicians should not only be informed of the beneficial effects but also the specific adverse effects of botanicals used for dermatologic disorders and

  3. Botanical Gardens and Collecting of Plants in the Light of the Metamorphosis of Botanical

    Full Text Available In the late 18th and early 19th century, the collecting of exotic plants became a fashion that took hold of European courts, and was followed by many noblemen, intellectuals, gardeners and others. It was not only popular to grow new plants in gardens, collecting them in herbaria or illustrating and enumerating them in catalogues, but was also important to develop botanical knowledge to enable the owners of the plants to use and present them. In Carniola we can observe this interest in botany in the cases of Baron Joseph Erberg, Barons Žiga and Karl Zois, Jesuit Gabriel Gruber as well as many others. Baron Erberg's activity is recorded in archives which include lively correspondence concerning plant collecting, the exchange and purchase of plants and other botanical matters. So we can see that among plant lovers in Carniola foreign plants such as pelargonium, agave and hydrangea were popular and that they had a special role in gardens devoted especially to exotic plants. The collecting of exotic plants is not just a phenomenon of the eighteenth and nineteenth centuries but can be traced back to early civilisations such the Assyrians and ancient Chinese and was also notable in a the 16th and 17th centuries with their cabinets of curiosities. But studying the botanical collection of exotic and new (or newly defined plants gardens of the late 18th and early 19th centuries shows us that although we can recognize some of the old “habits” in the process of collecting (collecting of rare, fascinating plants or collecting plants to demonstrate imperial power the social changes in the 18th century left their trace also in this aspect of human activity. Thus we can understand plant collecting of this time as a decline and metamorphosis of the former natural cabinets of curiosities. In botanical gardens of the late 18th and early 19th century we see the development of science of botany, the rise of the amateur botanist, a different perception of nature

    Salvia officinalis L. is an essential oil containing plant, which does not wildly grow in the territories of the Czech and Slovak Republics but it can be successfully cultivated. It is a perennial half-shrub, from which non-flowering herbaceous sprouts or leaves are collected for pharmaceutical purposes. After drying at a temperature not exceeding 35 degrees C they are the plant drugs Herba salviae or Folium salviae. In PhBs, Herba salviae is official. The drug contains mainly ethereal oil (1-2%), diterpenes, triterpenes and tannin. The pharmacopoeial criterion of quality is the content of essential oil, which is produced in an increased amount in the plant in warm summer months. Herba salviae and the extracts prepared from it are used as an antiseptic agent, an antiphlogistic agent, in the inflammations of the oral cavity and gingivitis and also as a stomachic and an antihydrotic agent. Its utilization in cosmetics and food industry is also of importance. PMID:8402963

    VHTR, one of the Generation IV reactor concepts, has a relatively high operation temperature and is usually suggested as a heat source for many industrial processes, including hydrogen production process. Thus, it is vital to trace tritium behavior in the VHTR system and the potential permeation rate to the industrial process. In other words, tritium is a crucial issue in terms of safety in the fission reactor system. Therefore, it is necessary to understand the behavior of tritium and the development of the tool to enable this is vital.. In this study, a Behavior of Tritium Analytic Code (BOTANIC) an analytic tool which is capable of analyzing tritium behavior is developed using a chemical process code called gPROMS. BOTANIC was then further verified using the analytic solutions and benchmark codes such as Tritium Permeation Analysis Code (TPAC) and COMSOL. In this study, the Behavior of Tritium Analytic Code, BOTANIC, has been developed using a chemical process code called gPROMS. The code has several distinctive features including non-diluted assumption, flexible applications and adoption of distributed permeation model. Due to these features, BOTANIC has the capability to analyze a wide range of tritium level systems and has a higher accuracy as it has the capacity to solve distributed models. BOTANIC was successfully developed and verified using analytical solution and the benchmark code calculation result. The results showed very good agreement with the analytical solutions and the calculation results of TPAC and COMSOL. Future work will be focused on the total system verification.

    The key issue of the safety assessment of botanical ingredients in personal care products (PCP) is the phytochemical characterisation of the plant source, data on contamination, adulteration and hazardous residues. The comparative approach used in the safety assessment of GM-plants may be applied to novel botanical PCP ingredients. Comparator(s) are the parent plant or varieties of the same species. Chemical grouping includes definition of chemical groups suitable for a read-across approach; it allows the estimation of toxicological endpoints on the basis of data from related substances (congeneric groups) with physical/chemical properties producing similar toxicities. The Threshold of Toxicological Concern (TTC) and Dermal Sensitisation Threshold (DST) are tools for the assessment of trace substances or minor ingredients. The evaluation of skin penetration of substances present in human food is unnecessary, whereas mixtures may be assessed on the basis of physical/chemical properties of individual substances. Adverse dermal effects of botanicals include irritation, sensitisation, phototoxicity and immediate-type allergy. The experience from dietary supplements or herbal medicines showed that being natural is not equivalent to being safe. Pragmatic approaches for quality and safety standards of botanical ingredients are needed; consumer safety should be the first objective of conventional and botanical PCP ingredients.

    Many hundreds of botanicals are used in complementary and alternative medicine for therapeutic use as antimicrobials and immune stimulators. While there exists many centuries of anecdotal evidence and few clinical studies on the activity and efficacy of these botanicals, limited scientific evidence exists on the ability of these botanicals to modulate the immune and inflammatory responses. Using botanogenomics (or herbogenomics), this study provides novel insight into inflammatory genes which are induced in peripheral blood mononuclear cells following treatment with immunomodulatory botanical extracts. These results may suggest putative genes involved in the physiological responses thought to occur following administration of these botanical extracts. Using extracts from immunostimulatory herbs (Astragalus membranaceus, Sambucus cerulea, Andrographis paniculata) and an immunosuppressive herb (Urtica dioica), the data presented supports previous cytokine studies on these herbs as well as identifying additional genes which may be involved in immune cell activation and migration and various inflammatory responses, including wound healing, angiogenesis, and blood pressure modulation. Additionally, we report the presence of lipopolysaccharide in medicinally prepared extracts of these herbs which is theorized to be a natural and active component of the immunostimulatory herbal extracts. The data presented provides a more extensive picture on how these herbs may be mediating their biological effects on the immune and inflammatory responses. PMID:20838436

    2014-01-01

    Plants have evolved a plethora of secondary chemicals to protect themselves against herbivores and pathogens, some of which have been used historically for pest management. The extraction methods used by industry render many phytochemicals ineffective as insecticides despite their bioactivity in the natural context. In this review, we examine how plants use their secondary chemicals in nature and compare this with how they are used as insecticides to understand why the efficacy of botanical insecticides can be so variable. If the commercial production of botanical insecticides is to become a viable pest management option, factors such as production cost, resource availability, and extraction and formulation techniques need be considered alongside innovative application technologies to ensure consistent efficacy of botanical insecticides.

    The rapid appraisal method was used to identify the botanicals used ethnomedicinally from a total of 300 randomly selected respondents drawn from the existing three geo-political zones of Ekiti State, Nigeria. The results obtained revealed that about 40% of the 71 botanicals identified presently rare. Most of the presently abundant botanicals are species primarily cultivated for other purpose other than medicine. Most of the identified species are valued for their curative effects on malaria and fever, the predominant diseases in the study area. The need for the conservation of the rare species cannot be over emphasised as most rural dwellers in the study area depend mostly on herbs from these species. Strategies towards the attainment of this goal are proposed.

    Madagascar is well-known for the exceptional biodiversity of its macro-flora and fauna, but the biodiversity of Malagasy microbial communities remains relatively unexplored. Understanding patterns of bacterial diversity in soil and their correlations with above-ground botanical diversity could influence conservation planning as well as sampling strategies to maximize access to bacterially derived natural products. We present the first detailed description of Malagasy soil bacterial communities from a targeted 16S rRNA gene survey of greater than 290,000 sequences generated using 454 pyrosequencing. Two sampling plots in each of three forest conservation areas were established to represent different levels of disturbance resulting from human impact through agriculture and selective exploitation of trees, as well as from natural impacts of cyclones. In parallel, we performed an in-depth characterization of the total vascular plant morphospecies richness within each plot. The plots representing different levels of disturbance within each forest did not differ significantly in bacterial diversity or richness. Changes in bacterial community composition were largest between forests rather than between different levels of impact within a forest. The largest difference in bacterial community composition with disturbance was observed at the Vohibe forest conservation area, and this difference was correlated with changes in both vascular plant richness and soil pH. These results provide the first survey of Malagasy soil bacterial diversity and establish a baseline of botanical diversity within important conservation areas.

    Full Text Available Plants are attacked by various phytopathogenic fungi. For many years, synthetic fungicides have been used to control plant diseases. Although synthetic fungicides are highly effective, their repeated use has led to problems such as environmental pollution, development of resistance, and residual toxicity. This has prompted intensive research on the development of biopesticides, including botanical fungicides. To date, relatively few botanical fungicides have been registered and commercialized. However, many scientists have reported isolation and characterization of a variety of antifungal plant derivatives. Here, we present a survey of a wide range of reported plant-derived antifungal metabolites.

  17. Soil contamination in plant samples and in botanical reference materials. Signature, quantification and consequences

    International Nuclear Information System (INIS)

    Individual samples of several sets of plants (lichens, tobacco, spruce needles, grass, botanical reference materials) show highly significant correlations of Al, Fe, Hf, La, Na, Th, Ti and V with Sc. These correlations result from the terrigenous part of aerosols deposited on and measured together with the plants. The composition of this contamination is almost uniform among the different plant sets and can be approximated by the composition of the upper continental crust. The mass of the terrigenous material ranges from 100 mg/g plant. Its presence is expected to lead to concentrations of the above and of other elements that deviate substantially from those of plants without contamination. This is proved by the comparison of two sets of spruce needles, one of which was measured without and the other after removal of the aerosol. (author)

    2011-06-30

    The use of botanical dietary supplements is increasingly popular, due to their natural origin and the perceived assumption that they are safer than prescription drugs. While most botanical dietary supplements can be considered safe, a few contain compounds, which can be converted to biological reactive intermediates (BRIs) causing toxicity. For example, sassafras oil contains safrole, which can be converted to a reactive carbocation forming genotoxic DNA adducts. Alternatively, some botanical dietary supplements contain stable BRIs such as simple Michael acceptors that react with chemosensor proteins such as Keap1 resulting in induction of protective detoxification enzymes. Examples include curcumin from turmeric, xanthohumol from hops, and Z-ligustilide from dang gui. Quinones (sassafras, kava, black cohosh), quinone methides (sassafras), and epoxides (pennyroyal oil) represent BRIs of intermediate reactivity, which could generate both genotoxic and/or chemopreventive effects. The biological targets of BRIs formed from botanical dietary supplements and their resulting toxic and/or chemopreventive effects are closely linked to the reactivity of BRIs as well as dose and time of exposure.

    Full Text Available In developed countries with westernized diets, the excessive consumption of added sugar in beverages and highly refined and processed foods is associated with increased risk for obesity, diabetes, and cardiovascular diseases. As a major constituent of added sugars, fructose has been shown to cause a variety of adverse metabolic effects, such as impaired insulin sensitivity, hypertriglyceridemia, and oxidative stress. Recent studies have shown that ketohexokinase isoform C is the key enzyme responsible in fructose metabolism that drive's fructose's adverse effects. The objective of this study was to identify botanical ingredients with potential for inhibitory activity against ketohexokinase-C and fructose-induced metabolic effects by using a series of in vitro model systems.Extracts from 406 botanicals and 1200 purified phytochemicals were screened (initial concentration of 50 μg/mL and 50 μM, respectively for their inhibitory activity using a cell free, recombinant human ketohexokinase-C assay. Dose response evaluations were conducted on botanical extracts and phytochemicals that inhibited ketohexokinase-C by > 30% and > 40%, respectively. Two different extract lots of the top botanical candidates were further evaluated in lysates of HepG2 cells overexpressing ketohexokinase-C for inhibition of fructose-induced ATP depletion. In addition, extracts were evaluated in intact Hep G2 cells for inhibition of fructose-induced elevation of triglyceride and uric acid production.Among the botanical extracts, phloretin (Malus domestica extracts were the most potent (IC50: 8.9-9.2 μg/mL followed by extracts of Angelica archangelica (IC50: 22.6 μg/mL-57.3 μg/mL. Among the purified phytochemicals, methoxy-isobavachalcone (Psoralea corylifolia, IC50 = 0.2 μM exhibited the highest potency against ketohexokinase isoform C activity followed by osthole (Angelica archangelica, IC50 = 0.7 μM, cratoxyarborenone E (Cratoxylum prunifolium, IC50 = 1.0 μM, and

    As leaders calling for the conservation of the world's plants, botanical gardens protect plants within living collections. Many also study, manage and restore plants in natural habitats. Royal Botanical Gardens (Ontario,Canada) has integrated both horticultural and natural heritage in its mission for decades. Envisioned by municipal leaders in the 1920s as a combination of nature sanctuaries and civic gardens, RBG now includes forests, wetlands and other habitats, gardens and built spaces. Today RBG is Canada's largest botanical garden on the basis of area.In the 1950s RBG began to inventory plant diversity. The checklist of spontaneous vascular plants now exceeds 1 170 species, of which 752 are native. This is 37% of Ontario's native vascular plants and 19% of the native vascular flora of Canada. The RBG nature sanctuaries are among the richest locations in Canada for species-level diversity.We examine the history of fioristic exploration within RBG and compare plant species-area relationships among protected natural areas in Ontario. This comparison supports the contention that the nature sanctuaries, and in particular Cootes Paradise, could be considered an important area for plants in Canada, and relative to the nation's flora, a biodiversity hotspot. The fact that a candidate vascular plant hotspot for Canada lies within a major botanical garden presents opportunities for raising public awareness of the importance of plant diversity, as well as focusing attention on the scientific and conservation biology needs of communities and individual species in this area.

    In traditional Chinese medicine, botanical remedies have been used for centuries to treat seizures. This review aimed to summarize the botanicals that have been used in traditional Chinese medicine to treat epilepsy. We searched Chinese online databases to determine the botanicals used for epilepsy in traditional Chinese medicine and identified articles using a preset search syntax and inclusion criteria of each botanical in the PubMed database to explore their potential mechanisms. Twenty-three botanicals were identified to treat epilepsy in traditional Chinese medicine. The pharmacological mechanisms of each botanical related to antiepileptic activity, which were mainly examined in animal models, were reviewed. We discuss the use and current trends of botanical treatments in China and highlight the limitations of botanical epilepsy treatments. A substantial number of these types of botanicals would be good candidates for the development of novel AEDs. More rigorous clinical trials of botanicals in traditional Chinese medicine for epilepsy treatment are encouraged in the future. This article is part of a Special Issue entitled "Botanicals for Epilepsy".

    Full Text Available Nonmelanoma skin cancers, including basal cell carcinoma and squamous cell carcinoma, are common neoplasms worldwide and are the most common cancers in the United States. Standard therapy for cutaneous neoplasms typically involves surgical removal. However, there is increasing interest in the use of topical alternatives for the prevention and treatment of nonmelanoma skin cancer, particularly superficial variants. Botanicals are compounds derived from herbs, spices, stems, roots, and other substances of plant origin and may be used in the form of dried or fresh plants, extracted plant material, or specific plant-derived chemicals. They possess multiple properties including antioxidant, anti-inflammatory, and immunomodulatory properties and are, therefore, believed to be possible chemopreventive agents or substances that may suppress or reverse the process of carcinogenesis. Here, we provide a review of botanical agents studied for the treatment and prevention of nonmelanoma skin cancers.

    2015-11-01

    Mood disorders are among the major health problems that exist worldwide. They are highly prevalent in the general population and cause significant disturbance of life quality and social functioning of the affected persons. The two major classes of mood disorders are bipolar disorders and depression. The latter is assumed to be the most frequent psychiatric comorbidity in epilepsy. Studies published during the second half of the 20th century recognized that certain patients with epilepsy present a depressed mood. Synthesized pharmaceuticals have been in use for decades to treat both mood disorders and epilepsy, but despite their efficiency, their use is limited by numerous side effects. On the other hand, animal models have been developed to deeply study potential botanicals which have an effect on mood disorders. Studies to investigate the potential effects of medicinal plants acting on the nervous system and used to treat seizures and anxiety are increasingly growing. However, these studies discuss the two conditions separately without association. In this review, we present animal models of depression and investigative models (methods of assessing depression) of depression and anxiety in animals. Other classical test models for prediction of clinical antidepressant activity are presented. Finally, this review also highlights antidepressant activities of herbals focusing specially on depression-like behaviors associated with epilepsy. The pharmacological properties and active principles of cited medicinal plants are emphasized. This review, therefore, provides an overview of the work done on botanicals for mood disorders, potential mechanisms of action of botanicals, and the major compounds.

    2013-05-01

    Menopausal women suffer from a variety of symptoms, including hot flashes and night sweats, which can affect quality of life. Although it has been the treatment of choice for relieving these symptoms, hormone therapy has been associated with increased breast cancer risk leading many women to search for natural, efficacious, and safe alternatives such as botanical supplements. Data from clinical trials suggesting that botanicals have efficacy for menopausal symptom relief have been controversial, and several mechanisms of action have been proposed including estrogenic, progestogenic, and serotonergic pathways. Plant extracts with potential estrogenic activities include soy, red clover, kudzu, hops, licorice, rhubarb, yam, and chasteberry. Botanicals with reported progestogenic activities are red clover, hops, yam, and chasteberry. Serotonergic mechanisms have also been proposed since women taking antidepressants often report a reduction in hot flashes and night sweats. Black cohosh, kudzu, kava, licorice, and dong quai all either have reported 5-hydroxytryptamine receptor 7 ligands or inhibit serotonin reuptake, therefore have potential serotonergic activities. Understanding the mechanisms of action of these natural remedies used for women's health could lead to more efficacious formulations and to the isolation of active components which have the potential of becoming effective medications in the future.

    In China, a new period of development in the first decaje of the 21st Century with rapid urbanization,was marked by investment in construction of over five billion yuan. At this time of rapid change it is important for botanical gardens to follow three principles, "scientific contents, artistic appearance, and cultural display", so as not to become public parks. The scientific component is important. It is not necessary for every botanical garden to do basic botanical research but they should all be involved in plant conservation issues, especially ex-situ conservation and keep accurate data on their living collections. Although a heavy responsibility this documentation is the foundation and the bottom line of scientific meaning for a botanical garden. Economic plant research, exploring new resources, was a major contribution of botanical gardens historically and remains important for sustainable cities and the national economy of China. Education and ecotourism are important ways for botanical gardens to serve the public displaying the interesting plant collections to enhance relaxation and well-being. It is reasonable to make income through all activities in a botanical garden but this should not be the major goal. It should be understood botanical gardens are comprehensive and multi-functional bodies determined by science, the arts and culture.

    Gymnosporia arenicola Jordaan (Celastraceae) is a shrub or small tree, which naturally occurs in coastal sand dunes of Southern Mozambique and South Africa. Its dried leaf is often used in traditional medicine for the treatment of infectious and inflammatory diseases. Hereby, we present results of studies carried out according to the pharmacopoeia standards for the identification of herbal drugs, in the whole, fragmented, and powdered plant material. These results were complemented with scanning electron microscopy and histochemical techniques. The leaf microscopic analysis revealed a typical dorsiventral mesophyll with a corresponding spongy parenchyma-palisade parenchyma ratio of 0.60, anomocytic and paracytic stomata, papillate cells with a diameter of 4.00 ± 0.40 µm, multicellular uniseriate nonglandular trichomes with a length of 27.00 ± 4.10 µm and cristalliferous idioblasts containing calcium oxalate cluster crystals with a diameter of 23.04 ± 5.84 µm. The present findings demonstrate that the G. arenicola leaf has both nonglandular trichomes and hypoderm, features not previously described in the corresponding botanical section (Gymnosporia sect. Buxifoliae Jordaan). The establishment of these new botanical markers for the identification of G. arenicola leaf is essential for quality, safety and efficacy reasons.

  5. On the definition of cannabinoids: botanical? chemical? pharmacological?

    Science.gov (United States)

    Weissman, A

    1981-01-01

    Cannabinoids (or presumed synonyms such as cannabinols or cannabis-like agents) have been variously defined in botanical, chemical, or pharmacological terms, with unfortunate consequences. Botanical definitions include inactive substances such as cannabigerol, as well as alkaloids and other secondary constituents of Cannabis sativa, but exclude synthetics such as levonantradol and nabilone. Chemical definitions include inactive close analogs of THC but exclude a growing number of substances structurally remote from THC that share its actions. Pharmacological definitions have depended on relatively nonspecific or vague behavioral endpoints. However, animal testing methodology has recently been developed that can identify and quantify agents that share THC's unique subjective effects. To avoid preexisting ambiquity in the word cannabinoids, the term cannabimimetics has been coined to include all such agents, regardless of origin or structure. Such a classification emphasizes research toward improved biological selectivity and therapeutic advance. While no totally noncannabimimetic agents with potent analgesic effects have yet been identified among derivatives of THC, selectivity has been uncovered for levonantradol, HHC (racemic-9-nor, 9-beta-OH-hexahydrocannabinol) and several structurally related compounds.

    Propolis is a non-toxic natural substance with multiple pharmacological properties including anti-cancer, antioxidant, fungicidal, antibacterial, antiviral, and anti-inflammatory among others. The aim of this study was to determine the chemical and botanical characterization of Chilean propolis samples and to evaluate their biological activity against the cariogenic bacteria Streptococcus mutans and Streptococcus sobrinus. Twenty propolis samples were obtained from beekeeping producers from the central and southern regions of Chile. The botanical profile was determined by palynological analysis. Total phenolic contents were determined using colorimetric assays. Reverse phase HPLC and HPLC-MS were used to determine the chemical composition. The minimum inhibitory concentration (MIC) was determined on S. mutans and S. sobrinus. All propolis samples were dominated by structures from native plant species. The characterization by HPLC/MS, evidenced the presence of quercetin, myricetin, kaempferol, rutine, pinocembrin, coumaric acid, caffeic acid and caffeic acid phenethyl ester, that have already been described in these propolis with conventional HPLC. Although all propolis samples inhibited the mutans streptococci growth, it was observed a wide spectrum of action (MIC 0.90 to 8.22 μg mL(-1)). Given that results it becomes increasingly evident the need of standardization procedures, where we combine both the determination of botanical and the chemical characterization of the extracts. Research conducted to date, describes a promising effectiveness of propolis in the prevention of caries and other diseases of the oral cavity, making it necessary to develop studies to identify and understand the therapeutic targets or mechanisms of molecular action of the various compounds present on them.

  12. John Locke's seed lists: a case study in botanical exchange.

    Harris, Stephen A; Anstey, Peter R

    2009-12-01

    This paper gives a detailed analysis of four seed lists in the journals of John Locke. These lists provide a window into a fascinating open network of botanical exchange in the early 1680s which included two of the leading botanists of the day, Pierre Magnol of Montpellier and Jacob Bobart the Younger of Oxford. The provenance and significance of the lists are assessed in relation to the relevant extant herbaria and plant catalogues from the period. The lists and associated correspondence provide the main evidence for Locke's own important, though modest contribution to early modern botany, a contribution which he would have regarded as a small part of the broader project of constructing a natural history of plants. They also provide a detailed case study of the sort of open and informal network of knowledge exchange in the early modern period that is widely recognised by historians of science, but all too rarely illustrated.

    The genus Eucalyptus (Myrtaceae) is mainly native to Australia; however, some species are now distributed globally. Eucalyptus has been used in indigenous Australian medicines for the treatment of a range of aliments including colds, flu, fever, muscular aches, sores, internal pains, and inflammation. Eucalyptus oils containing volatile compounds have been widely used in the pharmaceutical and cosmetics industries for a multitude of purposes. In addition, Eucalyptus extracts containing nonvolatile compounds are also an important source of key bioactive compounds, and several studies have linked Eucalyptus extracts with anticancer properties. With the increasing research interest in Eucalyptus and its health properties, this review briefly outlines the botanical features of Eucalyptus, discusses its traditional use as medicine, and comprehensively reviews its phytochemical and anticancer properties and, finally, proposes trends for future studies.

    Scorpion bite is considered as one of the common and dangerous phenomenon throughout the world. The clinical manifestations include pulmonary edema, myocardial damage, intracerebral haemorrhage, brachial plexopathy, renal failure etc. which sometimes leads to mortality. The common antivenin therapy includes anti-scorpion venom serum or prazosin. In the vast rural areas of the third world countries phytotherapy is considered as an alternative system of medicine and scorpion sting is treated with the help of medicinal botanicals. As the safety and efficacy are considered as important aspects of anti venin therapy, conventional treatment can be supported by the herbal remedy. The present review compiles a number of medicinal plants pharmacologically evaluated in vitro and/or in vivo for scorpion antivenin properties. Considering the aspects like cost effectiveness, availability, lesser side effects and development of drug resistance, plant based anti venin therapy may be considered as a possible remedy against scorpion envenomation.

    Despite numerous in vitro/vivo and phytochemical studies, the active constituents of Angelica sinensis (AS) have not been conclusively identified for the standardization to bioactive markers. Phytochemical analyses of AS extracts and fractions that demonstrate activity in a panel of in vitro bioassays, have repeatedly pointed to ligustilide as being (associated with) the active principle(s). Due to the chemical instability of ligustilide and related issues in GC/LC analyses, new methods capable of quantifying ligustilide in mixtures that do not rely on an identical reference standard are in high demand. This study demonstrates how NMR can satisfy the requirement for simultaneous, multi-target quantification and qualitative identification. First, the AS activity was concentrated into a single fraction by RP-solid-phase extraction, as confirmed by an (anti-)estrogenicity and cytotoxicity assay. Next, a quantitative 1H NMR (qHNMR) method was established and validated using standard compounds and comparing processing methods. Subsequent 1D/2D NMR and qHNMR analysis led to the identification and quantification of ligustilide and other minor components in the active fraction, and to the development of quality criteria for authentic AS preparations. The absolute and relative quantities of ligustilide, six minor alkyl phthalides, and groups of phenylpropanoids, polyynes, and poly-unsaturated fatty acids were measured by a combination of qHNMR and 2D COSY. The qNMR approach enables multi-target quality control of the bioactive fraction, and enables the integrated biological and chemical standardization of AS botanicals. This methodology can potentially be transferred to other botanicals with active principles that act synergistically, or that contain closely related and/or constituents, which have not been conclusively identified as the active principles.

    Phase I trials are an important part of traditional drug development in oncology. Such trials address two key issues: safety and dose. Currently, there is a dearth of phase I trials of anticancer botanicals. This may result from the apparently widespread view that a history of human use precludes the need for early-phase study. However, the safe use of a botanical by the population at large does not guarantee safety when the botanical is used in combination with other agents in the complex me...

  17. Analysis of small carbohydrates in several bioactive botanicals by gas chromatography with mass spectrometry and liquid chromatography with tandem mass spectrometry.

    Bioactive botanicals contain natural compounds with specific biological activity, such as antibacterial, antioxidant, immune stimulating, and taste improving. A full characterization of the chemical composition of these botanicals is frequently necessary. A study of small carbohydrates from the plant materials of 18 bioactive botanicals is further described. The study presents the identification of the carbohydrate using a gas chromatographic-mass spectrometric analysis that allows detection of molecules as large as maltotetraose, after changing them into trimethylsilyl derivatives. A number of carbohydrates in the plant (fructose, glucose, mannose, sucrose, maltose, xylose, sorbitol, and myo-, chiro-, and scyllo-inositols) were quantitated using a novel liquid chromatography with tandem mass spectrometric technique. Both techniques involved new method developments. The gas chromatography with mass spectrometric analysis involved derivatization and separation on a Rxi(®)-5Sil MS column with H2 as a carrier gas. The liquid chromatographic separation was obtained using a hydrophilic interaction type column, YMC-PAC Polyamine II. The tandem mass spectrometer used an electrospray ionization source in multiple reaction monitoring positive ion mode with the detection of the adducts of the carbohydrates with Cs(+) ions. The validated quantitative procedure showed excellent precision and accuracy allowing the analysis in a wide range of concentrations of the analytes.

  18. Adulteration screening of botanical materials by a sensitive and model-free approach using infrared spectroscopic imaging and two-dimensional correlation infrared spectroscopy

    2016-11-01

    Infrared (IR) spectroscopy is often used as a simple, fast, and green method for the adulteration screening of botanical materials for foods and herbs. However, the overlapping of absorption signals of various substances significantly decrease the sensitivity and specificity of IR spectroscopy in the detection of adulterated samples. In this research, a model-free approach is proposed for the sensitive and non-targeted screening of botanical materials adulterated by adding other plant materials. First, the spectra of the entities in the test sample are collected by near-infrared spectroscopic imaging and clustered by unsupervised pattern recognition methods. The sample may be adulterated if there are two or more clusters of the entities. Next, the entities of different clusters are characterized by mid-infrared spectroscopy to interpret the chemical compositions to determine the clustering is caused whether by adulteration or other reasons. Second derivative spectroscopy and two-dimensional correlation spectroscopy are often needed to resolve the overlapped bands mathematically or experimentally to find the characteristic signals to identify the authentic and adulterant entities. The feasibility of this approach was proved by the simulated adulterated sample of saffron. In conclusion, botanical materials adulterated by adding other plant materials can be detected by a simple, fast, sensitive, and green screening approach using IR spectroscopic imaging, two-dimensional correlation spectroscopy, and necessary chemometrics techniques.

    Commercial tannins from several botanical sources and with different chemical and technological characteristics are used in the food and winemaking industries. Different ways to check their botanical authenticity have been studied in the last few years, through investigation of different analytical parameters. This work proposes a new, effective approach based on the quantification of 6 carbohydrates, 7 polyalcohols, and 55 phenols. 87 tannins from 12 different botanical sources were analysed following a very simple sample preparation procedure. Using Forward Stepwise Discriminant Analysis, 3 statistical models were created based on sugars content, phenols concentration and combination of the two classes of compounds for the 8 most abundant categories (i.e. oak, grape seed, grape skin, gall, chestnut, quebracho, tea and acacia). The last approach provided good results in attributing tannins to the correct botanical origin. Validation, repeated 3 times on subsets of 10% of samples, confirmed the reliability of this model.

    Breast cancer risk has been associated with long-term estrogen exposure including traditional hormone therapy (HT, formally hormone replacement therapy). To avoid traditional HT and associated risks, women have been turning to botanical supplements such as black cohosh, red clover, licorice, hops, dong gui, and ginger to relieve menopausal symptoms despite a lack of efficacy evidence. The mechanisms of estrogen carcinogenesis involve both hormonal and chemical pathways. Botanical supplements could protect women from estrogen carcinogenesis by modulating key enzymatic steps [aromatase, P4501B1, P4501A1, catechol-O-methyltransferase (COMT), NAD(P)H quinone oxidoreductase 1 (NQO1), and reactive oxygen species (ROS) scavenging] in estradiol metabolism leading to estrogen carcinogenesis as outlined in Figure 1. This review summarizes the influence of popular botanical supplements used for women's health on these key steps in the estrogen chemical carcinogenesis pathway, and suggests that botanical supplements may have added chemopreventive benefits by modulating estrogen metabolism.

    Botanical products are widely used in nutritional supplementation for promotion of health or prevention of diseases. With the high prevalence of obesity and type 2 diabetes, abnormalities in carbohydrate metabolism are common in the general population and obtaining glycemic control is important in reducing the complications of diabetes. If shown to be effective, botanical products have a unique position in potentially aiding the general public in regard to obesity and diabetes. They can be obtained "over-the-counter" and may have less side effects compared to many synthetic drugs. Although most of the popular botanicals have a long history in folk medicine, there is paucity of data regarding their efficacy and safety, particularly as it relates to human studies. In this review, we discuss the data that was available in the literature for nine botanicals that are frequently promoted to help manage blood glucose. They are Bitter Melon (Momordica charantia), Fenugreek (trigonella foenum graecum), Gymnema Sylvestre, Ivy Gourd (Coccinia indica), Nopal or Prickly Pear Cactus (Opuntia streptacantha), Ginseng, Aloe Vera, Russian Tarragon (Artemisia dracunculus), and Garlic (Allium sativum). The discussion is emphasized on the clinical aspect of these botanicals. Due to the lack of sufficient evidence from clinical studies for any of the botanicals reviewed, it is premature to actively recommend use of any particular herb to treat either glucose or other risk factors. Thus, well defined randomized clinical trials are warranted in this area. PMID:18537692

    The use of reference solutions dispersed on filter paper discs is proposed for the first time as an external calibration strategy for matrix matching and determination of As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Sr, V and Zn in plants by laser ablation-inductively coupled plasma mass spectrometry (LA-ICP-MS). The procedure is based on the use of filter paper discs as support for aqueous reference solutions, which are further evaporated, resulting in solid standards with concentrations up to 250 μg g(-1) of each element. The use of filter paper for calibration is proposed as matrix matched standards due to the similarities of this material with botanical samples, regarding to carbon concentration and its distribution through both matrices. These characteristics allowed the use of (13)C as internal standard (IS) during the analysis by LA-ICP-MS. In this way, parameters as analyte signal normalization with (13)C, carrier gas flow rate, laser energy, spot size, and calibration range were monitored. The calibration procedure using solution deposition on filter paper discs resulted in precision improvement when (13)C was used as IS. The method precision was calculated by the analysis of a certified reference material (CRM) of botanical matrix, considering the RSD obtained for 5 line scans and was lower than 20%. Accuracy of LA-ICP-MS determinations were evaluated by analysis of four CRM pellets of botanical composition, as well as by comparison with results obtained by ICP-MS using solution nebulization after microwave assisted digestion. Plant samples of unknown elemental composition were analyzed by the proposed LA method and good agreement were obtained with results of solution analysis. Limits of detection (LOD) established for LA-ICP-MS were obtained by the ablation of 10 lines on the filter paper disc containing 40 μL of 5% HNO3 (v v(-1)) as calibration blank. Values ranged from 0.05 to 0.81  μg g(-1). Overall, the use of filter paper as support for dried aqueous

    Gmelina asiatica Linn (G. parvifolia Roxb.) is a large shrub or a small tree. Roots and aerial parts are used in Ayurvedic medicine and also have ethno-medical uses. Root is reported as adulterant to G. arborea roxb roots. Pharmacognostical characters of root were reported. Owing to the shortage of genuine drug and ever-increasing demands in market, it becomes necessary to search an alternative with equal efficacy without compromising the therapeutic value. Nowadays, it becomes a common practice of using stem. In case of roots phytochemical and pharmacological analysis of stem was reported. However, there is no report on the pharmacognostical characters of stem and to differentiate it from roots. The present report describes the botanical pharmacognostical characters of stem and a note to differentiate it from root. Hollow pith, faint annual rings in cut ends, alternatively arranged macrosclereids and bundle cap fibers, and presence of abundant starch grains and calcium oxalates in pith and in ray cells are the diagnostic microscopic characters of stem. Stem pieces can be differentiated from roots by absence of tylosis. PMID:23661867

    Full Text Available Eighteen samples of honeys which were harvested over several beekeeping seasons from apiaries located in the area of the “Kózki” Nature Reserve (central-eastern Poland were the subject of the present study. The “Kózki” Nature Reserve is included in the European Ecological Network Natura 2000 program. A microscopic analysis of the pollen sediment in the honeys showed the presence of 61 pollen types from 32 botanical families in the investigated material. There were represented by nectariferous (72.1% and nonnectariferous plants (27.9% and both entomophilous and anemophilous ones. The total number of pollen taxa in individual samples ranged from 13 to 37. The main sources of nectar from trees and shrubs were: Frangula alnus, Prunus, Robinia pseudacacia, Rubus, Salix, Tilia. The main sources of nectar from herbaceous plants were: Anthriscus, Brassicaceae, Caryophyllaceae, Centaurea cyanus, Taraxacum, and Trifolium repens. Four unifloral honeys (three fruit tree honeys and one lime honey and fourteen multifloral honeys, with a significant percentage of pollen from several nectariferous plant taxa, were distinguished in the studied material.

    Full Text Available The overall control of the quality of botanical drugs starts from the botanical raw material, continues through preparation of the botanical drug substance and culminates with the botanical drug product. Chromatographic and spectroscopic fingerprinting has been widely used as a tool for the quality control of herbal/botanical medicines. However, discussions are still on-going on whether a single technique provides adequate information to control the quality of botanical drugs. In this study, high performance liquid chromatography (HPLC, ultra performance liquid chromatography (UPLC, capillary electrophoresis (CE and near infrared spectroscopy (NIR were used to generate fingerprints of different plant parts of Panax notoginseng. The power of these chromatographic and spectroscopic techniques to evaluate the identity of botanical raw materials were further compared and investigated in light of the capability to distinguishing different parts of Panax notoginseng. Principal component analysis (PCA and clustering results showed that samples were classified better when UPLC- and HPLC-based fingerprints were employed, which suggested that UPLC- and HPLC-based fingerprinting are superior to CE- and NIR-based fingerprinting. The UPLC- and HPLC- based fingerprinting with PCA were able to correctly distinguish between samples sourced from rhizomes and main root. Using chemometrics and its ability to distinguish between different plant parts could be a powerful tool to help assure the identity and quality of the botanical raw materials and to support the safety and efficacy of the botanical drug products.

    Taylor, John G.

    The Composites market is arguably the most challenging and profitable market for phenolic resins aside from electronics. The variety of products and processes encountered creates the challenges, and the demand for high performance in critical operations brings value. Phenolic composite materials are rendered into a wide range of components to supply a diverse and fragmented commercial base that includes customers in aerospace (Space Shuttle), aircraft (interiors and brakes), mass transit (interiors), defense (blast protection), marine, mine ducting, off-shore (ducts and grating) and infrastructure (architectural) to name a few. For example, phenolic resin is a critical adhesive in the manufacture of honeycomb sandwich panels. Various solvent and water based resins are described along with resin characteristics and the role of metal ions for enhanced thermal stability of the resin used to coat the honeycomb. Featured new developments include pultrusion of phenolic grating, success in RTM/VARTM fabricated parts, new ballistic developments for military vehicles and high char yield carbon-carbon composites along with many others. Additionally, global regional market resin volumes and sales are presented and compared with other thermosetting resin systems.

    We present experimental evidence to reveal the mechanism of long-range penetration of low-energy ions in botanic samples. In the 100keV Ar+ ion transmission measurement, the result confirmed that low-energy ions could penetrate at least 60μm thick kidney bean slices with the probability of about 1.0 × 10-5. The energy spectrum of 1 MeV He+ ions penetrating botanic samples has shown that there is a peak of the count of ions with little energy loss. The probability of the low-energy ions penetrating the botanic sample is almost the same as that of the high-energy ions penetrating the same samples with little energy loss. The results indicate that there are some micro-regions with mass thickness less than the projectile range of low-energy ions in the botanic samples and they result in the long-range penetration of low-energy ions in botanic samples.

    Background: Honey has multiple therapeutic properties due to its composition with diverse components. Objectives: This study aims to investigate the antimicrobial efficacy of Saharan honeys against bacterial pathogens, the variation of honey floral origins, and its physicochemical characteristics. Materials and Methods: The antimicrobial activity of 32 samples of honey collected from the Algerian Sahara Desert was tested on four bacteria; Bacillus subtilis, Clostridium perfringens, Escherichia coli, and Staphylococcus aureus. The botanical origin of honeys and their physicochemical properties were determined and their combined antibacterial effects were modeled using a generalized linear mixed model (GLMM). Results: Out of the 32 study samples, 14 were monofloral and 18 were multifloral. The pollen density was on average 7.86 × 106 grains/10 g of honey, water content was 14.6%, electrical conductivity (EC) was 0.5 μS/cm, pH was 4.38 ± 0 50, hydroxymethylfurfural (HMF) content was 82 mg/kg of honey, total sugars = 83%, reducing sugars = 71%, and the concentration of proline = 525.5 ± 550.2 mg/kg of honey. GLMM revealed that the antibacterial effect of honey varied significantly between bacteria and floral origins. This effect increased with increasing of water content and reducing sugars in honey, but it significantly decreased with increase of honey EC. E. coli was the most sensitive species with an inhibition zone of 10.1 ± 4.7 mm, while C. perfringens was the less sensitive. Honeys dominated by pollen of Fabaceae sp. were most effective with an overall antimicrobial activity equals to 13.5 ± 4.7 mm. Conclusion: Saharan honeys, of certain botanical origins, have physicochemical and pollinic characteristics with relevant potential for antibacterial purposes. This encourages a more comprehensive characterization of honeys with in vivo and in vitro investigations. PMID:26594206

    Full Text Available Systematic studies carried out in the greenhouses of the Botanical Garden - Center for Biological Diversity Conservation of the Polish Academy of Sciences in Warsaw-Powsin revealed that the flora of weeds ras very rich there. A total of 243 taxa of vascular plants and 17 species of bryophytes were recorded. With regard to the division of the flora of vascular plants according to species origin and degree of naturalization, it was found that native plants (89 species, greenhouse-escapes (87 species and permanently established aliens (48 species co-dominated there. In addition, 10 species of garden-escapes, i.e. plants cultivated in the immediate neighbourhood of greenhouses, were recorded indoors. Noteworthy were two species that had been brought accidentally to the glasshouses together with plant material - this group of plants is least numerous but quite frequent in the study area. Observations made in the vicinity of Powsin greenhouses showed that relationships between the studied flora and the plants growing outside were unilateral. In Powsin no proved example of expansion of greenhouse plants to other parts of the Garden has been recorded. By contrast, influx of diaspores to the study area is observed frequently - the flora of greenhouse weeds is dominated by plants found also in the immediate neighbourhood (147 species. The most important factors affecting the composition of the weed flora of glasshouses include the flora of the surrounding areas and the mode of greenhouse management (e.g. the range of species cultivated there. The diversity of the flora is not related to greenhouse size.

    2013-02-27

    The possibility of tracing the botanical and geographical origin of products such as honey has become more important because of market globalization. As a consequence, numerous analytical methods have been applied to the determination of honey authenticity. The scope of the present work is to chromatographically purify and characterize 23 compounds from organic extracts of unifloral (chestnut, linden, orange, acacia, eucalyptus, honeydew) and polyfloral honeys. Of these compounds, 17 were identified as specific markers and were used for botanical discrimination in a previous study based on multivariate statistical analysis of proton nuclear magnetic resonance ((1)H NMR) data. Together with the botanical markers, 6 other substances were isolated and characterized using NMR and mass spectrometry. These phytochemicals belong to several classes, that is, terpenes, organic acids, flavonoids, and others. For the first time, a diacylglyceryl ether and 5 other compounds present in different types of honey were identified and characterized. PMID:23360363

    2011-04-01

    Full Text Available Floristic studies were carried out in eight botanical gardens in Poland in the years 1992-1999. It was demonstrated that the spontaneous synanthropic flora of the gardens consisted of 1092 taxa in the rank of a genus or lower, among which alien species constituted 55% of the flora studied. Ergasiophygophytes, of which the introduction is closely associated with the activities of the botanical gardens, dominated in the latter group of species. It appeared that the flora of the studied botanical gardens was rather similar. However, the structure of the flora of different spatial units (six types of microhabitats distinguished in the particular gardens varied, which was associated with the various management practices. The flora of microhabitats identified in the gardens differed with respect to the number of taxa and spectra of geographical-historical groups of species and life forms. Ruderal sites, arable lands and roadsides supported the highest number of taxa (the flora of the above spatial units was represented by 646, 645 and 597 taxa, respectively. Moreover, they were characterized by a high proportion of annual plants in the flora (43, 38 and 34%, respectively and by a relatively small representation of apophytes (39% in all the three types of microhabitats. The flora of wet areas and parks was, however, poor in species (154 and 403 species, respectively, but relatively rich in apophytes (72 and 55% of the flora, respectively and with a low contribution of therophytes (19 and 20%, respectively. The present data were compared with the findings of other authors who investigated the synanthropic flora of cities in which the botanical gardens were located. The comparative analysis of the flora of Poznań and Łódź showed a great richness of species (in relation to size of the area studied and a high incidence of aliens (especially those, which had not become established permanently in the botanical gardens.

  17. Carl Linnaeus, Erasmus Darwin and Anna Seward: Botanical Poetry and Female Education

    Science.gov (United States)

    George, Sam

    2014-03-01

    This article will explore the intersection between `literature' and `science' in one key area, the botanical poem with scientific notes. It reveals significant aspects of the way knowledge was gendered in the Enlightenment, which is relevant to the present-day education of girls in science. It aims to illustrate how members of the Lichfield Botanical Society (headed by Erasmus Darwin) became implicated in debates around the education of women in Linnaean botany. The Society's translations from Linnaeus inspired a new genre of women's educational writing, the botanical poem with scientific notes, which emerged at this time. It focuses in particular on a poem by Anna Seward and argues that significant problems regarding the representation of the Linnaean sexual system of botany are found in such works and that women in the culture of botany struggled to give voice to a subject which was judged improper for female education. The story of this unique poem and the surrounding controversies can teach us much about how gender impacted upon women's scientific writing in eighteenth century Britain, and how it shaped the language and terminology of botany in works for female education. In particular, it demonstrates how the sexuality of plants uncovered by Linnaeus is a paradigmatic illustration of how societal forces can simultaneously both constrict and stimulate women's involvement in science. Despite the vast changes to women's access in scientific knowledge of the present day, this `fair sexing' of botany illustrates the struggle that women have undergone to give voice to their botanical knowledge.

  18. Development of botanical principles for clinical use in cancer: where are we lacking?

    2012-01-01

    Development of drugs from plant sources (botanicals) for the treatment of cancer has not been successful in India, despite a plethora of medicinal plants and an equal number of experiments demonstrating anti-cancer activity of plant principles in vitro. There are several pitfalls in our approach to botanical drug development. Foremost is the lack of industry-academia collaborations in this field. Research goals in Indian academic institutions are generally short-term and mostly aimed at fulfilling the minimum requirements of a doctoral/MD or MPharm thesis. Secondly, quality assurance of herbal formulations is difficult to achieve and good manufacturing practices are expensive to implement. This could introduce bias during the biological evaluation of botanicals. A systematic approach covering a wide range of investigations including but not limited to mechanistic studies, potential herb-drug interactions, pharmacokinetics and bioavailability could help in the optimization of herbal formulations in the preclinical stage of development before they can be considered for clinical trials. Government initiatives such as Ayurveda, Unani, Siddha and Homeopathic have encouraged research in these areas, but are insufficient to promote focused and aggressive evaluation of potential herbs. Particular emphasis should be given to clinical pharmacokinetics, drug interactions and clinical trials in specific cancers for the evaluation of dosage, safety, efficacy and concomitant use with chemotherapy. Only such policies can result in meaningful evaluation of botanicals for cancer therapy.

  4. Influence of botanic origin and amylose content on the morphology of starch nanocrystals

    International Nuclear Information System (INIS)

    Starch nanocrystals (SNC) are crystalline platelets resulting from the disruption of the semi-crystalline structure of starch granules by the acid hydrolysis of amorphous parts. The aim of this study was to assess the influence of botanic origin and amylose content of native starches on the morphology and properties of resulting nanoparticles. SNC were prepared from five different starches normal maize, high amylose maize, waxy maize, potato, and wheat; covering three botanic origins, two crystalline types, and three range of amylose content (0, 25, and 70%) for maize starch. Different types of nanocrystals were obtained with a thickness ranging between 4 and 8 nm and diameter from about 50 to 120 nm depending on the source. The comparison of their morphology, crystallinity, and rheological properties is proposed for the first time. For the same amylose content, maize, potato, and wheat resulted in rather similar size and crystallinity of SNC proving the limited influence of the botanic origin. For the same botanic origin (maize), differences in size were more important indicating the influence of the amylopectin content. Also, particles tended to show square shapes with increasing native starch’s amylopectin content and A-type crystalinity. Thus, only high amylose content starches should be avoided to prepare SNC.

    Full Text Available Development of drugs from plant sources (botanicals for the treatment of cancer has not been successful in India, despite a plethora of medicinal plants and an equal number of experiments demonstrating anti-cancer activity of plant principles in vitro. There are several pitfalls in our approach to botanical drug development. Foremost is the lack of industry-academia collaborations in this field. Research goals in Indian academic institutions are generally short-term and mostly aimed at fulfilling the minimum requirements of a doctoral/MD or MPharm thesis. Secondly, quality assurance of herbal formulations is difficult to achieve and good manufacturing practices are expensive to implement. This could introduce bias during the biological evaluation of botanicals. A systematic approach covering a wide range of investigations including but not limited to mechanistic studies, potential herb-drug interactions, pharmacokinetics and bioavailability could help in the optimization of herbal formulations in the preclinical stage of development before they can be considered for clinical trials. Government initiatives such as Ayurveda, Unani, Siddha and Homeopathic have encouraged research in these areas, but are insufficient to promote focused and aggressive evaluation of potential herbs. Particular emphasis should be given to clinical pharmacokinetics, drug interactions and clinical trials in specific cancers for the evaluation of dosage, safety, efficacy and concomitant use with chemotherapy. Only such policies can result in meaningful evaluation of botanicals for cancer therapy.

    Full Text Available Plants and animals with features which identify them as supernaturals characterize the art of the Precolumbian Moche culture of northern Peru. Among these animals is a frog with feline attributes and a consistent association with manioc tubers, stalks, and plants, the Botanical Frog. The Botanical Frog appears to have been patterned on Leptodactylus pentadactylus. It is shown copulating with felines. Fine line painted vessels and ones with low relief decoration show the Botanical Frog performing as part of a ritual involving other animals and cultivated crops, suggesting that the Botanical Frog was associated with agriculture.

    Microglia play a significant role in the generation and propagation of oxidative/nitrosative stress, and are the basis of neuroinflammatory responses in the central nervous system. Upon stimulation by endotoxins such as lipopolysaccharides (LPS), these cells release pro-inflammatory factors which can exert harmful effects on surrounding neurons, leading to secondary neuronal damage and cell death. Our previous studies demonstrated the effects of botanical polyphenols to mitigate inflammatory responses induced by LPS, and highlighted an important role for cytosolic phospholipase A2 (cPLA2) upstream of the pro-inflammatory pathways (Chuang et al. in J Neuroinflammation 12(1):199, 2015. doi: 10.1186/s12974-015-0419-0 ). In this study, we investigate the action of botanical compounds and assess whether suppression of cPLA2 in microglia is involved in the neurotoxic effects on neurons. Differentiated SH-SY5Y neuroblastoma cells were used to test the neurotoxicity of conditioned medium from stimulated microglial cells, and WST-1 assay was used to assess for the cell viability of SH-SY5Y cells. Botanicals such as quercetin and honokiol (but not cyanidin-3-O-glucoside, 3CG) were effective in inhibiting LPS-induced nitric oxide (NO) production and phosphorylation of cPLA2. Conditioned medium from BV-2 cells stimulated with LPS or IFNγ caused neurotoxicity to SH-SY5Y cells. Decrease in cell viability could be ameliorated by pharmacological inhibitors for cPLA2 as well as by down-regulating cPLA2 with siRNA. Botanicals effective in inhibition of LPS-induced NO and cPLA2 phosphorylation were also effective in ameliorating microglial-induced neurotoxicity. Results demonstrated cytotoxic factors from activated microglial cells to cause damaging effects to neurons and potential use of botanical polyphenols to ameliorate the neurotoxic effects.

The study was performed on small-plot trial over 7 years on moderately moist grassland in the Czech Republic. The proportion of legumes was significantly higher in the treatments fertilized with cow manure + dung-water combined with medium intensive utilization and intensive utilization (10.2% and 10.3%, respectively. Fertilization significantly increased dry matter yields by 51.9% (cow manure + dung water and 56% (cattle slurry compared with unfertilized controls (4.81 t/ha. Grasslands fertilized with cattle slurry showed significantly higher concentration of crude protein (142.9 g/kg compared with unfertilized (126.4 g/kg. Extensive grassland utilization significantly affected the increase of crude fibre concentration (up to 282.1 g/kg, and decrease of the energy value (up to 4.68 MJ g/kg of NEL. Organic matter digestibility was also negatively influenced by extensive grassland utilization (61.0%, 65.42% and 67.44% for the extensive, medium intensive and intensive utilization, respectively. Our findings suggested that medium intensive and intensive grassland utilization by the organic fertilization, which corresponded to annual doses of nitrogen of 84 and 120 kg/ha were the most suitable from the viewpoint of animal nutrition.

  1. A hybridized membrane-botanical biofilter for improving air quality in occupied spaces

    Llewellyn, David; Darlington, Alan; van Ras, Niels; Kraakman, Bart; Dixon, Mike

    Botanical biofilters have been shown to be effective in improving indoor air quality through the removal of complex mixtures of gaseous contaminants typically found in human-occupied environments. Traditional, botanical biofilters have been comprised of plants rooted into a thin and highly porous synthetic medium that is hung on vertical surfaces. Water flows from the top of the biofilter and air is drawn horizontally through the rooting medium. These botanical biofilters have been successfully marketed in office and institutional settings. They operate efficiently, with adequate contaminant removal and little maintenance for many years. Depending on climate and outdoor air quality, botanical biofiltration can substantially reduce costs associated with ventilation of stale indoor air. However, there are several limitations that continue to inhibit widespread acceptance: 1. Current designs are architecturally limiting and inefficient at capturing ambient light 2. These biofilters can add significant amounts of humidity to an indoor space. This water loss also leads to a rapid accumulation of dissolved salts; reducing biofilter health and performance 3. There is the perception of potentially actively introducing harmful bioaerosols into the air stream 4. Design and practical limitations inhibit the entrance of this technology into the lucrative residential marketplace This paper describes the hybridization of membrane and botanical biofiltration technologies by incorporating a membrane array into the rootzone of a conventional interior planting. This technology has the potential for addressing all of the above limitations, expanding the range of indoor settings where botanical biofiltration can be applied. This technology was developed as the CSA-funded Canadian component an ESA-MAP project entitled: "Biological airfilter for air quality control of life support systems in manned space craft and other closed environments", A0-99-LSS-019.

    Several pentacyclic triterpenoid acids including betulinic, oleanolic, and ursolic acids were reported to have health beneficial properties such as antiviral and anti-inflammatory properties, as well as the capability to inhibit "in vitro" the development of various cancer cell types. For this reason betulinic, oleanolic, and ursolic acids are used as neutraceuticals. For the analysis of the pentacyclic triterpenoid acids in complex plant materials, an improved scheme was developed, involving a qualitative screening using silylation and gas chromatography with mass spectrometry analysis, followed by quantitation using a novel liquid chromatography with tandem mass spectrometry procedure. The use of the two methods provides more reliable information regarding the plant materials with unknown composition. Besides betulinic, oleanolic, and ursolic acids that were analyzed, by this procedure a fourth pentacyclic triterpenoid acid was identified and quantitated that was not previously reported to be present in plants. This acid has been identified as 3β-3-hydroxy-lupa-18,20(29)-dien-28-oic acid. The newly identified acid has a structure as a derivative of lupane, although lupane with a double bond in the 18-position was not previously reported as present in plants. The new liquid chromatography with tandem mass spectrometry procedure developed for this study offers a very low limit of quantitation, excellent precision, and robustness. Rosemary was found to contain the largest levels of pentacyclic triterpenoid acids among all the analyzed botanicals. PMID:26549610

    Full Text Available Pollen spectrum, physicochemical parameters and volatile fraction of Corsican “spring” honeys were investigated with the aim of developing a multidisciplinary method for the qualification of honeys in which nectar resources are under-represented in the pollen spectrum. Forty-one Corsican “spring” honeys were certified by melissopalynological analysis using directory and biogeographical origin of 50 representative taxa. Two groups of honeys were distinguished according to the botanical origin of samples: “clementine” honeys characterized by the association of cultivated species from oriental plain and other “spring” honeys dominated by wild herbaceous taxa from the ruderal and/or maquis area. The main compounds of the “spring” honey volatile fraction were phenylacetaldehyde, benzaldehyde and methyl-benzene. The volatile composition of “clementine” honeys was also characterized by three lilac aldehyde isomers. Statistical analysis of melissopalynological, physicochemical and volatile data showed that the presence of Citrus pollen in “clementine” honeys was positively correlated with the amount of linalool derivatives and methyl anthranilate. Otherwise, the other “spring” honeys were characterized by complex nectariferous species associations and the content of phenylacetaldehyde and methyl syringate.

    Full Text Available Background: Honey has multiple therapeutic properties due to its composition with diverse components.Objectives: This study aims to investigate the antimicrobial efficacy of Saharan honeys against bacterial pathogens, the variation of honey floral origins and its physicochemical characteristics.Materials and Methods: The antimicrobial activity of 32 samples of honey collected from the Algerian Sahara Desert was tested on four pathogenic bacteria; Bacillus subtilis, Clostridium perfringens, Escherichia coli and Staphylococcus aureus. The botanical origin of honeys and their physicochemical properties were determined and their combined antibacterial effects were modeled using a generalized linear mixed model (GLMM.Results: Out of the 32 study samples, 14 were monofloral and 18 were multifloral. The pollen density was on average 7.86 × 106 grains/10 g of honey, water content was 14.6%, electrical conductivity was 0.5 μS/cm, pH was 4.38±0 50, hydroxymethylfurfural content was 82 mg/kg of honey, total sugars = 83%, reducing sugars = 71%, and the concentration of proline = 525.5±550.2 mg/kg of honey. GLMM revealed that the antibacterial effect of honey varied significantly between bacteria and floral origins. This effect increased with increasing of water content and reducing sugars in honey, but it significantly decreased with increase of honey electrical conductivity. E. coli was the most sensitive species with an inhibition zone of 10.1±4.7 mm, while C. perfringens was the less sensitive with 3.9±5.4 mm. Honeys dominated by pollen of Fabaceae sp. were most effective with an overall antimicrobial activity equals to 13.5±4.7 mm.Conclusion: Saharan honeys, of certain botanical origins, have physicochemical and pollinic characteristics with relevant potential for antibacterial purposes. This encourages a more comprehensive characterization of honeys with in vivo and in vitro investigations.Keywords: Honey characterization; antibacterial effects

    2015-01-01

    Crohn's disease and ulcerative colitis are the two most common categories of inflammatory bowel disease (IBD), which are characterized by chronic inflammation of the intestine that comprises the patients' life quality and requires sustained pharmacological and surgical treatments. Since their aetiology is not completely understood, nonfully efficient drugs have been developed and those that show effectiveness are not devoid of quite important adverse effects that impair their long-term use. Therefore, many patients try with some botanical drugs, which are safe and efficient after many years of use. However, it is necessary to properly evaluate these therapies to consider a new strategy for human IBD. In this report we have reviewed the main botanical drugs that have been assessed in clinical trials in human IBD and the mechanisms and the active compounds proposed for their beneficial effects.

    Prosser, Sean W J; Hebert, Paul D N

    2017-01-01

    Honey is generated by various bee species from diverse plants, and because the value of different types of honey varies more than 100-fold, it is a target for fraud. This paper describes a protocol that employs DNA metabarcoding of three gene regions (ITS2, rbcLa, and COI) to provide an inexpensive tool to simultaneously deliver information on the botanical and entomological origins of honey. This method was used to examine seven varieties of honey: light, medium, dark, blended, pasteurized, creamed, and meliponine. Plant and insect sources were identified in five samples, but only the botanical or insect source could be identified in the other two. Two samples were found to be misrepresented. Although this method was generally successful in determining both plant and insect sources, honeys rich in polyphenolic compounds or subject to crystallization were recalcitrant to analysis, so further research is required to combat honey adulteration and mislabeling.

    In this study, the Harenna forest honey samples were investigated with respect to their botanical origin, granulation, colour and sensory properties. Sixteen honey samples were collected from two representative sites (Chiri, C, and Wabero, W) using random sampling techniques. Botanical origin was investigated using qualitative pollen analysis by counting 500 pollen grains using harmonised methods of melissopalynology. Granulation, colour, and sensory properties of honey were determined by visual observation, using Pfund grader, acceptability and preference tests, respectively. Honey samples were also tested for tetracycline. Honey obtained from Wabero is originated dominantly from Syzygium guineense while Chiri was multifloral. The colour of honey ranged from 34 to 85 with light amber and extra light amber colours. The honey samples were free from tetracycline residue and form coarse granules slowly. Significant variation (p>0.05) in sensory preference and acceptability tests not observed due to hive types and locations.

    Full Text Available In this study, we observed the flowering phenology, breeding system, pollination and seed germination of four species of Calligonum (C. calliphysa, C. rubicundum, C. densum and C. ebinuricum in the Turpan Eremophytes Botanic Garden, China. Our results showed that the species had overlapping flowering phenologies and were pollinated by similar pollination agents. Their breeding systems were self-compatible, and with signs of outbreeding, but not of hybridization with each other; the main isolation mechanism was post-zygotic isolation and they also had high seed germination rates. Therefore, they are suited to ex situ conservation in the Turpan Eremophytes Botanic Garden, and can supply sufficient seeds for renewal populations and the conservation of germplasm resources. Furthermore, these results provide theoretical support for the construction of a national germplasm resource garden of Calligonum, and for the introduction to the garden of other eremophyteplants and their conservation.

    2008-07-01

    Twelve xanthone constituents of the botanical dietary supplement mangosteen (the pericarp of Garcinia mangostana) were screened using a noncellular, enzyme-based microsomal aromatase inhibition assay. Of these compounds, garcinone D (3), garcinone E (5), alpha-mangostin (8), and gamma-mangostin (9) exhibited dose-dependent inhibitory activity. In a follow-up cell-based assay using SK-BR-3 breast cancer cells that express high levels of aromatase, the most potent of these four xanthones was gamma-mangostin (9). Because xanthones may be consumed in substantial amounts from commercially available mangosteen products, the consequences of frequent intake of mangosteen botanical dietary supplements require further investigation to determine their possible role in breast cancer chemoprevention.

    Full Text Available PrefaceThis is the official Report on the deliberations and decisions of the ten sessions of the Nomenclature Section of the XVII International Botanical Congress held in Vienna, Austria, from 12–16 July 2005. The meetings of the Section took place on these five consecutive days prior to the Congress proper. The Section meetings were hosted by the Institute of Botany, University of Vienna, Austria. Technical facilities included full electronic recording of all discussion spoken into the microphones. Text of all proposals to amend the Code was displayed on one screen allowing suggested amendments to be updated as appropriate. The team at the University of Vienna (Christopher Dixon, Jeong-Mi Park, Ovidiu Paun, Carolin A. Redernig and Dieter Reich ensured that the proceedings ran smoothly and enjoyably for all.A report of the decisions of the Section was published soon after the Congress (McNeill & al. in Taxon 54: 1057–1064. 2005. It includes a tabulation of the preliminary mail vote on the published proposals, specifying how the Section acted on each and detailing amendments and new proposals approved upon motions from the floor. It also includes the report of the Nominating Committee as well as the Congress resolution ratifying the Section’s decisions, neither reproduced here. The main result of the Section’s deliberations is the Vienna Code, which was published as Regnum Vegetabile 146, on 20 Sep 2006 (McNeill & al. in Regnum Veg. 146. 2006. It was also published online, on the same date (see http://www.iapt-taxon.org/nomen/main.php.The present report of the proceedings of the Vienna Nomenclature Section conveys, we believe, a true and lively picture of the event. It is primarily based on the MP3 electronic recordings, with, where necessary, supplementation by the comment slips submitted by most speakers and by reference to parallel tape-recording, particularly where there were gaps in the MP3 record. With these sources combined, and

    Full Text Available Herbal medicines are often combinations of botanical extracts that are assumed to have additive or synergistic effects. The purpose of this investigation was to compare the effect of individual botanical extracts with combinations of extracts on prostate cell viability. We then modeled the interactions between botanical extracts in combination isobolographically. Scutellaria baicalensis, Rabdosia rubescens, Panax-pseudo ginseng, Dendranthema morifolium, Glycyrrhiza uralensis and Serenoa repens were collected, taxonomically identified and extracts prepared. Effects of the extracts on cell viability were quantitated in prostate cell lines using a luminescent ATP cell viability assay. Combinations of two botanical extracts of the four most active extracts were tested in the 22Rv1 cell line and their interactions assessed using isobolographic analysis. Each extract significantly inhibited the proliferation of prostate cell lines in a time- and dose-dependent manner except repens. The most active extracts, baicalensis, D. morifolium, G. uralensis and R. rubescens were tested as two-extract combinations. baicalensis and D. morifolium when combined were additive with a trend toward synergy, whereas D. morifolium and R. rubescens together were additive. The remaining two-extract combinations showed antagonism. The four extracts together were significantly more effective than the two-by-two combinations and the individual extracts alone. Combining the four herbal extracts significantly enhanced their activity in the cell lines tested compared with extracts alone. The less predictable nature of the two-way combinations suggests a need for careful characterization of the effects of each individual herb based on their intended use.

    Full Text Available Directive 2002/32/EC of the European Parliament and of the Council of 7 May 2002 on undesirable substances in animal feed lists a range of substances from botanical origin (weed seeds and additionally some chemical compounds directly originating from specific weeds. In order to examine the actual status of enforcement and of the present occurrence of these botanical substances, a survey was carried out. A questionnaire was sent to 103 laboratories, including official control labs from all member states of the European Union. The results, indicating the frequency of occurrence as far as reported, are compared to the publications of the EU Rapid Alert System for Food and Feed (RASFF. A total of 44 questionnaires was returned (42.7% from 22 member states. Ten member states predominantly from north-western Europe appeared to have an active monitoring of botanical undesirable substances. The questionnaire results did not indicate that the other member states enforce this part of Directive 2002/32/EC. Reports on the frequency of occurrence include: a few to 25-50% of the samples contain traces of ergot (8 member states, a few to 24% contain at least some traces of thorn apple (6 member states, zero to 17% contain some castor oil plant seeds (3 member states, zero to a few samples contain Crotalaria seeds (3 member states, and zero to 6% contain traces of Sareptian mustard (4 member states. One member state conducted extra surveillance since several cases of animal intoxications have been reported. In some cases a coincidence with undesirable botanical substances was found.

    2016-09-01

    In the past decades, the use of traditional medicine has increased globally, leading to a booming herbal medicine and dietary supplement industry. The increased popularity of herbal products has led to a rise in demand for botanical raw materials. Accurate identification of medicinal herbs is a legal requirement in most countries and prerequisite for delivering a quality product that meets consumer expectations. Traditional identification methods include botanical taxonomy, macroscopic and microscopic examination, and chemical methods. Advances in the identification of biological species using DNA-based techniques have led to the development of a DNA marker-based platform for authentication of plant materials. DNA barcoding, in particular, has been proposed as a means to identify herbal ingredients and to detect adulteration. However, general barcoding techniques using universal primers have been shown to provide mixed results with regard to data accuracy. Further technological advances such as mini-barcodes, digital polymerase chain reaction, and next generation sequencing provide additional tools for the authentication of herbs, and may be successful in identifying processed ingredients used in finished herbal products. This review gives an overview on the strengths and limitations of DNA barcoding techniques for botanical ingredient identification. Based on the available information, we do not recommend the use of universal primers for DNA barcoding of processed plant material as a sole means of species identification, but suggest an approach combining DNA-based methods using genus- or species-specific primers, chemical analysis, and microscopic and macroscopic methods for the successful authentication of botanical ingredients used in the herbal dietary supplement industry.

    Full Text Available This study aimed to evaluate the insecticidal activity of eight botanical species in the behavior and biological development of Zabrotes subfasciatus (Coleoptera: Chrysomelidae: Bruchinae under laboratory conditions. The botanical species were applied on bean grains (Phaseolus vulgaris Linnaeus directly as powder or indirectly within TNT bags. Three laboratory assays were performed. First, a repellent activity test was performed by exposing twenty couples of Z. subfasciatus adults in a choice-test arena. Second, a mortality test was performed for seven days after infestation. Finally, the oviposition and emergency rates of adults (% and the development from egg to adult (in days were evaluated in seven couples (males and females for seven days inside of a vial containing 0.3g of the powder from each botanical species and 10 g of bean grains (3% w.w-1. The study was conducted in a completely randomized design, and the treatments were arranged as a factorial design (2 x 9 with two factors (factor 1= powder and TNT bag application forms and factor 2= eight botanical species and control with eight replications. The powder application form was more efficient in controlling Z. subfasciatus. Azadirachta indica (powder application, Ruta graveolens (powder application, and Piper aduncum (TNT bag reduced the infestation of adults. The species A. inidica, Piper tuberculatum, Trichilia catigua, Pfaffia glomerata, R. graveolens, and Mentha pulegium inhibited the oviposition of the insects regardless of the formulation applied. R. graveolens (powder application caused 100% of mortality. The powder application of R. graveolens and M. pulegium reduced egg viability and insect emergence; therefore, they are very promising alternatives to control Z. subfasciatus in stored grains.

    Full Text Available Indonesia, being part of the center of origin of bananas (Musaceae, has a large number diversity of bananas both wild seeded species and edible seedless cultivated varieties. Inventory of wild Musa species in Purwodadi Botanic Garden has been conducted through compiling data records from PBG’s Registration section, field inspection and observation to living collections in the garden, herbarium specimens and literature studies. The results show that total 17 wild Musa accessions has been recorded planted in Purwodadi Botanic Garden since 1990 until 2012; comprises of 8 Musa acuminata sub species, 2 Musa balbisiana forms, 1 Musa ornata, 1 Musa troglodytarum, 1 Musa borneensis and 4 unidentified species Musa spp.; but only 8 living accessions remained in 2012. Morphotaxonomic review of those 8 wild Musa accessions remained will be discussed in this paper including their geographical distributions. According to its differentiated morphological characteristics observations, it is known that there are three accessions were resembled cultivars and one unidentified species have been determined its species level, so that their registration identity needs to be revised. It is important next to prioritize ex-situ conservation of wild Musa species not yet collected in Purwodadi Botanic Garden especially from Eastern Indonesia.

  16. A novel insight into the cost–benefit model for the evolution of botanical carnivory

    Science.gov (United States)

    Pavlovič, Andrej; Saganová, Michaela

    2015-01-01

    Background The cost–benefit model for the evolution of botanical carnivory provides a conceptual framework for interpreting a wide range of comparative and experimental studies on carnivorous plants. This model assumes that the modified leaves called traps represent a significant cost for the plant, and this cost is outweighed by the benefits from increased nutrient uptake from prey, in terms of enhancing the rate of photosynthesis per unit leaf mass or area (AN) in the microsites inhabited by carnivorous plants. Scope This review summarizes results from the classical interpretation of the cost–benefit model for evolution of botanical carnivory and highlights the costs and benefits of active trapping mechanisms, including water pumping, electrical signalling and accumulation of jasmonates. Novel alternative sequestration strategies (utilization of leaf litter and faeces) in carnivorous plants are also discussed in the context of the cost–benefit model. Conclusions Traps of carnivorous plants have lower AN than leaves, and the leaves have higher AN after feeding. Prey digestion, water pumping and electrical signalling represent a significant carbon cost (as an increased rate of respiration, RD) for carnivorous plants. On the other hand, jasmonate accumulation during the digestive period and reprogramming of gene expression from growth and photosynthesis to prey digestion optimizes enzyme production in comparison with constitutive secretion. This inducibility may have evolved as a cost-saving strategy beneficial for carnivorous plants. The similarities between plant defence mechanisms and botanical carnivory are highlighted.

    Ferri, Gianmarco; Alù, Milena; Corradini, Beatrice; Beduschi, Giovanni

    2009-09-01

    Forensic botany can provide significant supporting evidence during criminal investigations. However, it is still an underutilized field of investigation with its most common application limited to identifying specific as well as suspected illegal plants. The ubiquitous presence of plant species can be useful in forensics, but the absence of an accurate identification system remains the major obstacle to the present inability to routinely and correctly identify trace botanical evidence. Many plant materials cannot be identified and differentiated to the species level by traditional morphological characteristics when botanical specimens are degraded and lack physical features. By taking advantage of a universal barcode system, DNA sequencing, and other biomolecular techniques used routinely in forensic investigations, two chloroplast DNA regions were evaluated for their use as "barcoding" markers for plant identification in the field of forensics. We therefore investigated the forensic use of two non-coding plastid regions, psbA-trnH and trnL-trnF, to create a multimarker system for species identification that could be useful throughout the plant kingdom. The sequences from 63 plants belonging to our local flora were submitted and registered on the GenBank database. Sequence comparison to set up the level of identification (species, genus, or family) through Blast algorithms allowed us to assess the suitability of this method. The results confirmed the effectiveness of our botanic universal multimarker assay in forensic investigations. PMID:19504263

  18. Extraction of DNA from honey and its amplification by PCR for botanical identification

    Directory of Open Access Journals (Sweden)

    Sona Arun Jain

    2013-12-01

    Full Text Available The physiochemical and biological properties of honey are directly associated to its floral origin. Some current commonly used methods for identification of botanical origin of honey involve palynological analysis, chromatographic methods, or direct observation of the bee behavior. However, these methods can be less sensitive and time consuming. DNA-based methods have become popular due to their simplicity, quickness, and reliability. The main objective of this research is to introduce a protocol for the extraction of DNA from honey and demonstrate that the molecular analysis of the extracted DNA can be used for its botanical identification. The original CTAB-based protocol for the extraction of DNA from plants was modified and used in the DNA extraction from honey. DNA extraction was carried out from different honey samples with similar results in each replication. The extracted DNA was amplified by PCR using plant specific primers, confirming that the DNA extracted using the modified protocol is of plant origin and has good quality for analysis of PCR products and that it can be used for botanical identification of honey.

  19. What Does It Mean to be Central? A Botanical Geography of Paris 1830-1848.

    Hoquet, Thierry

    2016-02-01

    This paper focuses on the geography of the botanical community in Paris, under the July Monarchy (1830-1848). At that time, the Muséum d'Histoire naturelle (MHN) was at its institutional acme and, under the impulse of François Guizot, its budget was increasing dramatically. However, closer attention to manuscript sources (correspondence, travel diaries) reveals that the botanists of the time favoured other private institutions, located both on the Right and Left Banks of the Seine. The MHN was prestigious for its collections and professors but it was relatively remote from the centre of Paris, and its plant samples were sometimes difficult to access. Several other first-class private herbaria granted liberal access to botanists: those of Jacques Gay, Phillip Barker Webb, and Benjamin Delessert. Thanks to their wealth, these plant amateurs had ownership of historical herbaria consisting of species types alongside rich botanical libraries. Botanists visiting Paris from foreign countries or other provinces of France also spent some time studying less general plant collections, like those of Count Jaubert, or specialized collections, like Montagne's or Léveillé's on cryptogams. Other botanists also enjoyed renown at the time, although they published little, if anything (like Maire). Living in crammed apartments, literally in the middle of their plant samples, these botanists were key nodes in botanical networks, although they had no relation with the prestigious MHN.

    Full Text Available At the beginning of the 20th century, Otto Müller described over 100 new freshwater diatom taxa from algae samples, collected during the German “Nyassa-See– und Kinga-Gebirgs-Expedition” in East Africa. He published valuable drawings and wrote detailed descriptions of these microalgae, but subsequent authors regarded many of these African taxa to be synonyms or infraspecific of European species. In the last two decades renewed attention to the diatom flora of East Africa has made it evident that Müller’s taxa have to be reinvestigated, in terms of both light as well as scanning electron microscopy, in order to evaluate possible new or endemic species. This was recently done for his Surirella taxa, a typical component of the African Great Lakes diatom flora of which many species are endemic to this area. Additional data, originating from material of later periods in the same region (e.g. Lakes Tanganyika, Malawi, Victoria, Edward, was incorporated in the investigation to study the variability in valve morphology and the African distribution of each species. Otto Müller’s samples thus provide the means to study historical African diatom diversity as a baseline for modern biodiversity assessment. Type information and the English description for taxon have been published in international journals and online at the AlgaTerra Information System [www.algaterra.org], a site developed and updated by the Botanic Garden and Botanical Museum Berlin-Dahlem (BGBM. High resolution digital photographs of the Surirella taxa will also be available in the future on the API website [www.aluka.org].

    Genotoxicity testing is an important part of preclinical safety assessment of new drugs and is required prior to Phase I/II clinical trials. It is designed to detect genetic damage such as gene mutations and chromosomal aberration, which may be reflected in tumorigenic or heritable mutation potential of the drug. Botanical new drugs in the U.S. are entitled to a waiver for preclinical pharmacology/toxicology studies, including genotoxicity testing, in support of an initial clinical trial under IND, contingent on previous human experience. Recently, ethical concerns have been raised over conducting Phase I/II clinical trials of new drugs with positive genotoxicity findings in healthy volunteers. Although the relevance of this issue to patients, as opposed to healthy volunteers, depends on the drug's indication, duration of treatment, and specific findings related to the assays, the regulatory view is to avoid exposing patients to genotoxic compounds unnecessarily in clinical trials. This philosophy may impact on herbal supplement marketing and botanical drug development, in that genotoxicity data are often lacking while consumers are exposed to the herbal supplement, or healthy volunteers are tested in an initial Phase I/II clinical trial on the botanical drug. This paper presents results of a survey conducted on genotoxicity data in botanical INDs submitted to the Agency and discusses the significance of this information. The information presented indicates that the sponsors of botanical INDs have increasingly recognized the importance of genotoxicity information and may have prioritized its acquisition in their strategic drug development programs.

    Carmela Fimognari

    Full Text Available BACKGROUND: Although cancers are characterized by the deregulation of multiple signalling pathways, most current anticancer therapies involve the modulation of a single target. Because of the enormous biological diversity of cancer, strategic combination of agents targeted against the most critical of those alterations is needed. Due to their complex nature, plant products interact with numerous targets and influence several biochemical and molecular cascades. The interest in further development of botanical drugs has been increasing steadily and the FDA recently approved the first new botanical prescription drug. The present study is designed to explore the potential antileukemic properties of Hemidesmus indicus with a view to contributing to further development of botanical drugs. Hemidesmus was submitted to an extensive in vitro preclinical evaluation. METHODOLOGY/PRINCIPAL FINDINGS: A variety of cellular assays and flow cytometry, as well as a phytochemical screening, were performed on different leukemic cell lines. We have demonstrated that Hemidesmus modulated many components of intracellular signaling pathways involved in cell viability and proliferation and altered the protein expression, eventually leading to tumor cell death, mediated by a loss of mitochondrial transmembrane potential and increased Bax/Bcl-2 ratio. ADP, adenine nucleotide translocator and mitochondrial permeability transition pore inhibitors did not reverse Hemidesmus-induced mitochondrial depolarization. Hemidesmus induced a significant [Ca(2+](i raise through the mobilization of intracellular Ca(2+ stores. Moreover, Hemidesmus significantly enhanced the antitumor activity of three commonly used chemotherapeutic drugs (methotrexate, 6-thioguanine, cytarabine. A clinically relevant observation is that its cytotoxic activity was also recorded in primary cells from acute myeloid leukemic patients. CONCLUSIONS/SIGNIFICANCE: These results indicate the molecular basis of

    Iodine has been used as an effective tool for studying both the structure and composition of dispersed starch and starch granules. In addition to being employed to assess relative amylose contents for starch samples, it has been used to look at the molecular mobility of the glucose polymers within intact starch granules based on exposure to iodine vapor equilibrated at different water activities. Starches of different botanical origin including corn, high amylose corn, waxy corn, potato, waxy potato, tapioca, wheat, rice, waxy rice, chick pea and mung bean were equilibrated to 0.33, 0.75, 0.97 water activities, exposed to iodine vapor and then absorbance spectra and LAB color were determined. In addition, a new iodine quantification method sensitive to distribution of granules, and the density of the starch were also determined to explore whether high levels of long linear glucose chains and the surface area-to-volume ratio were important factors relating to the granular iodine binding. Results showed, in all cases, starches complexed more iodine as water content increased and waxy starches bound less iodine than their normal starch counterparts. However, much more bound iodine could be measured chemically with waxy starches than was expected based on colorimetric determination. Surface area appeared to be a factor as smaller rice and waxy rice starch granules complexed more iodine, while the larger potato and waxy potato granules complexed less than would be expected based on measured amylose contents. Corn, high amylose corn, and wheat, known to have starch granules with extensive surface pores, bound higher levels of iodine suggesting pores and channels may be an important factor giving iodine vapor greater access to bind within the granules. Exposing iodine vapor to moisture-equilibrated native starches is an effective tool to explore starch granule architecture. PMID:21962455

    Research shows a dramatic increase in use of the medical system during times of stress, such as job insecurity. Stress is a factor in many illnesses - from headaches to heart disease, and immune deficiencies to digestive problems. A substantial contributor to stress-induced decline in health appears to be an increased production of stress hormones and subsequent decreased immune function. Non-pharmaceutical approaches have much to offer such patients. This article focuses on the use of nutrients and botanicals to support the adrenals, balance neurotransmitters, treat acute anxiety, and support restful sleep.

    The skin and its immune system manifest a decline in physiologic function as it undergoes aging. External insults such as ultraviolet light exposure cause inflammation, which may enhance skin aging even further leading to cancer and signs of photoaging. There is a potential role for botanicals as an adjunct modality in the prevention of skin aging. Numerous over-the-counter anti-aging products are commercially available, many of which boast unverified claims to reduce stress, inflammation and correct signs of aging. In this article we reviewed the scientific literature for data on frequently published "anti-inflammaging" additives such as vitamins A, C and E and green tea. We also analyzed the evidence available on five promising ingredients commonly found in anti-aging products, namely, argan oil, rosemary, pomegranate, Coenzyme Q10, and Coffeeberry. Though there may be an increasing amount of scientific data on a few of these novel botanicals, in general, there remains a lack of clinical data to support the anti-aging claims made.

  20. Piecing together the biogeographic history of Chenopodium vulvaria L. using botanical literature and collections

    Full Text Available This study demonstrates the value of legacy literature and historic collections as a source of data on environmental history. Chenopodium vulvaria L. has declined in northern Europe and is of conservation concern in several countries, whereas in other countries outside Europe it has naturalised and is considered an alien weed. In its European range it is considered native in the south, but the northern boundary of its native range is unknown. It is hypothesised that much of its former distribution in northern Europe was the result of repeated introductions from southern Europe and that its decline in northern Europe is the result of habitat change and a reduction in the number of propagules imported to the north. A historical analysis of its ecology and distribution was conducted by mining legacy literature and historical botanical collections. Text analysis of habitat descriptions written on specimens and published in botanical literature covering a period of more than 200 years indicate that the habitat and introduction pathways of C. vulvaria have changed with time. Using the non-European naturalised range in a climate niche model, it is possible to project the range in Europe. By comparing this predicted model with a similar model created from all observations, it is clear that there is a large discrepancy between the realized and predicted distributions. This is discussed together with the social, technological and economic changes that have occurred in northern Europe, with respect to their influence on C. vulvaria.

    Vegetation is sparsely distributed over Antarctica's ice-free ground, and distinct plant communities are present in each of the continent's 15 recently identified Antarctic Conservation Biogeographic Regions (ACBRs). With rapidly increasing human activity in Antarctica, terrestrial plant communities are at risk of damage or destruction by trampling, overland transport, and infrastructure construction and from the impacts of anthropogenically introduced species, as well as uncontrollable pressures such as fur seal (Arctocephalus gazella) activity and climate change. Under the Protocol on Environmental Protection to the Antarctic Treaty, the conservation of plant communities can be enacted and facilitated through the designation of Antarctic Specially Protected Areas (ASPAs). We examined the distribution within the 15 ACBRs of the 33 ASPAs whose explicit purpose includes protecting macroscopic terrestrial flora. We completed the first survey using normalized difference vegetation index (NDVI) satellite remote sensing to provide baseline data on the extent of vegetation cover in all ASPAs designated for plant protection in Antarctica. Large omissions in the protection of Antarctic botanical diversity were found. There was no protection of plant communities in 6 ACBRs, and in another 6, Antarctic continent; over half was within a single protected area. Over 96% of the protected vegetation was contained in 2 ACBRs, which together contributed only 7.8% of the continent's ice-free ground. We conclude that Antarctic botanical diversity is clearly inadequately protected and call for systematic designation of ASPAs protecting plant communities by the Antarctic Treaty Consultative Parties, the members of the governing body of the continent.

Moreover, gas chromatography-mass spectrometry (GC-MS) analysis was carried to identify the chemical components of the most effective plant extract against T. granarium. Furthermore, the safety of the most effective plant extract was evaluated with respect to biochemical and histological changes in treated rats relative to control. The results revealed that, the tested botanical extracts showed high efficiency against T. granarium with respect to mortality and progeny of the adults. C. senna was the most effective botanical extract against T. granarium. The GC-MS analysis of the most effective plant extract showed the presence of different bioactive compounds that is known by its insecticidal activity. The most effective plant extract showed no toxicity on treated rats relative to control with respect to biochemical and histological changes. The results suggest the ability of using these plant extracts for wheat grains protection as a safe alternative to insecticides.

    International Nuclear Information System (INIS)

    Ethno botanical studies of economically important plants from Gilgit-Baltistan were conducted during 2003-2006. Extensive field trips were conducted for collection of plants according to their flowering and fruiting period and ethno-botanical data obtained during field trips. This area has many ecological zones, lies between 3000ft to 29000ft above sea level. Due to difference in soil, climate, moisture contents, latitude, longitude, altitude and topography, great diversity of plants of economic importance were found in these areas. Locals belonging to different ethnic groups, like, sayed, Gujjar, Mughal, Sheen, Yaskuin, Wakhi, Tajik, Khowar, etc., are settled there. They have distinct life styles, beliefs, traditions, life style and culture. There is a great shortage medical treatment therefore locals use indigenous plants for treatment of various diseases at local level. Folklore treatment is considered the cheapest source of curing diseases at local level. Information regarding ethno-medicinal importance was obtained from local inhabitants of old age. These plants have been utilised over many generations by various ethnic groups. It was found that indigenous medicinal flora of the area is quite rich and is diverse, due to the difference in altitude, climate and other topographic conditions. It is expected that this paper will be beneficial for locals, students, researchers, farmers, foresters and general public alike. (author)

    In 1868, Lydia Becker (1827-1890), the renowned Manchester suffragist, announced in a talk before the British Association for the Advancement of Science that the mind had no sex. A year later, she presented original botanical research at the BAAS, contending that a parasitic fungus forced normally single-sex female flowers of Lychnis diurna to develop stamens and become hermaphroditic. This essay uncovers the complex relationship between Lydia Becker's botanical research and her stance on women's rights by investigating how her interest in evolutionary theory, as well as her correspondence with Charles Darwin, critically informed her reform agendas by providing her with a new vocabulary for advocating for equality. One of the facts that Becker took away from her work on Lychnis was that even supposedly fixed, dichotomous categories such as biological sex became unfocused under the evolutionary lens. The details of evolutionary theory, from specific arguments on structural adaptations to more encompassing theories on heredity (i.e., pangenesis), informed Becker's understanding of human physiology. At the same time, Becker's belief in the fundamental equality of the sexes enabled her to perceive the distinction between inherent, biological differences and culturally contingent ones. She applied biological principles to social constructs as she asked: Do analogous evolutionary forces act on humans? PMID:23961688

    In Canada, the use of botanical natural health products (NHPs) for anxiety disorders is on the rise, and a critical evaluation of their safety and efficacy is required. The purpose of this study was to determine whether commercially available botanicals directly affect the primary brain enzymes responsible for gamma-aminobutyric acid (GABA) metabolism. Anxiolytic plants may interact with either glutamic acid decarboxylase (GAD) or GABA transaminase (GABA-T) and ultimately influence brain GABA levels and neurotransmission. Two in vitro rat brain homogenate assays were developed to determine the inhibitory concentrations (IC50) of aqueous and ethanolic plant extracts. Approximately 70% of all extracts that were tested showed little or no inhibitory effect (IC50 values greater than 1 mg/mL) and are therefore unlikely to affect GABA metabolism as tested. The aqueous extract of Melissa officinalis (lemon balm) exhibited the greatest inhibition of GABA-T activity (IC50 = 0.35 mg/mL). Extracts from Centella asiatica (gotu kola) and Valeriana officinalis (valerian) stimulated GAD activity by over 40% at a dose of 1 mg/mL. On the other hand, both Matricaria recutita (German chamomile) and Humulus lupulus (hops) showed significant inhibition of GAD activity (0.11-0.65 mg/mL). Several of these species may therefore warrant further pharmacological investigation. The relation between enzyme activity and possible in vivo mode of action is discussed. PMID:18066140

    Historical research may be able to contribute to the exploration of traditional knowledge about medicinal plants and promising attempts have been made investigating Byzantine texts, Early Modern herbals, and writings of Christian missionaries. In this pilot study it should be explored if publications, travel reports, diaries or correspondence of the botanical explorers of the 19th and early 20th centuries may serve a source of ethnopharmacological information as well and may be able to guide modern phytopharmacological research. Writings of Berthold Seemann (1825-1871), a German investigator exploring the botany of Middle America, the Fiji islands and other regions, are investigated as a first example. It could be shown that Seemann's heritage mainly kept at Kew Garden Archives, does contain ethnopharmacological information which in part has already been confirmed by recent study results indicating some reliability of his observations. However, there are also reports about traditional medicinal plants scarcely investigated so far, including Schultesia stenophylla Mart. (syn. S. guainensis (Aubl.) Malme), Trixis inula Crantz, Waltheria glomerata Presl., Gonophlebium attenuatum (Humb. & Bonpl. Es Wil\\d) C. Presl., or Pseudoelephantopus spicatus (Juss ex Aubl.) C.F. Baker. It is suggested to further explore their potential as medicinal plants. In general, as Seemann's example has shown, publications and correspondence of botanical explorers of the past seem to be a valuable and hitherto almost neglected source of information to be considered in further historical and ethnopharmacological research.

    Full Text Available (1 This study examines the effect of increasing botanical diversity, through reed-bed planting and maintenance regimes, on sewage treatment reed-bed invertebrate biodiversity and the possible enrichment of overall catchment biodiversity. (2 Reed-bed invertebrates were identified as a good indicator group of overall site biodiversity quality and were sampled at a range of sewage treatment reed-bed sites in the same geographical area between May and August 2006 (plus one natural reed-bed control site. Standardised water trapping and pitfall trapping techniques were employed throughout this sampling period. (3 Statistical analysis of the sampling results revealed that the number of plant species recorded was inversely related to terrestrial invertebrate species richness, species conservation value index and biomass within the study sites. For example, the natural reed-bed sampled had the highest botanical diversity but the lowest terrestrial invertebrate species richness. (4 This study has demonstrated that sewage treatment reed-beds support a diverse range of invertebrate species, some of them being of national conservation value. This suggests that sewage treatment reed-beds may be at least as biodiverse as naturally occurring reed-beds and will add to the overall biodiversity and ecohydrology of a catchment whilst saving energy.

    Full Text Available Mutaqien Z, Zuhri M (2011 Establishing a long-term permanent plot in remnant forest of Cibodas Botanic Garden, West Java. Biodiversitas 12: 218-224. Cibodas Botanic Garden (CBG has unique characters; almost 10% of which is forested area adjacent to the natural forest of Mt. Gede Pangrango National Park. The area is a transition between natural forest and artificial habitat which mostly consists of exotic plant species. The permanent plot in CBG was established in 2007-2009. Two hundred and eighty four units of 10x10 square meters sub-plot were established in four locations, i.e. Wornojiwo, Kompos, Jalan Akar, and Lumut forest. Vegetation analyses were conducted for trees, saplings, shrubs, and herb species. The inventory found 137 species plants consisting of 74 tree species dominated by Villebrunea rubescens (Bl. Bl. and Ostodes paniculata Bl., 30 shrub species dominated by Strobilanthes hamiltoniana (Steud., 24 herb species dominated by Cyrtandra picta Bl., 6 fern species mainly consisted of Diplazium pallidum Moore, and 3 climber species dominated by Calamus reinwardtii Mart. In comparison with the natural forest of Mt. Gede Pangrango National Park, the CBG permanent plot showed a good representative of the vegetation of lower montane forest. A regular monitoring during the successive years is needed to maintain diversity, monitor forest dynamics and anticipate the spread of invasive plant from CBG.

    Full Text Available Abstract Background Maintenance of the botanical integrity of cereal kernels and the addition of acetic acid (as vinegar in the product or meal has been shown to lower the postprandial blood glucose and insulin response and to increase satiety. However, the mechanism behind the benefits of acetic acid on blood glucose and satiety is not clear. We hypothesized that the gastric emptying rate could be involved. Thus, the aim of this study was to evaluate the possible influence of maintained botanical integrity of cereals and the presence of acetic acid (vinegar on gastric emptying rate (GER, postprandial blood glucose and satiety. Methods Fifteen healthy subjects were included in a blinded crossover trial, and thirteen of the subjects completed the study. Equicarbohydrate amounts of the following wheat-based meals were studied: white wheat bread, whole-kernel wheat bread or wholemeal wheat bread served with white wine vinegar. The results were compared with a reference meal consisting of white wheat bread without vinegar. The GER was measured with standardized real-time ultrasonography using normal fasting blood glucose Results The whole-kernel wheat bread with vinegar resulted in significantly higher ( Conclusion The present study shows higher satiety after a whole-kernel wheat bread meal with vinegar. This may be explained by increased antral distension after ingestion of intact cereal kernels but, in this study, not by a lower gastric emptying rate or higher postprandial blood glucose response.

It also addresses the university’s botany professors / garden directors and assistant directors, focusing in more detail on the learned gardeners, who were more notable for their activities prior to commencing work in Tartu or during or after their Tartu period. A total of 22 learned gardeners and 14 assistant learned gardeners have been identified. Among them were persons from Germany , as well as representatives of other nationalities, including Estonians, Poles, Russians and local Germans. The employment duration of the learned gardeners at the botanical garden lasted from a few months to 42 years. The longest serving learned gardener was Wilhelm Eduard Stelling, a local German. Among the learned gardeners, the career and activities of Johann Anton Weinmann, Ludwig Riedel and Jan Muszynski stood out. After leaving Tartu, Weinmann and Muszynski became outstanding researchersin St. Petersburg and Poland, respectively, and Riedel emerged as a sucessful plant collector, scientific organiser and developer of park culture in Brazil.

    Aparna, S.; Ved, Devendra Kumar; Lalitha, S.; Venkatasubramanian, Padma

    2012-01-01

    Background: Daśamūla (DM) is a top-traded group of medicinal plants used by the Ayurvedic industry. Through literature survey and analysis, this article has enlisted the botanical sources of DM, as correlated by several scholars. Such a list is not available from any single, earlier publication. It brings to light the confusion that exists in terms of botanical sources correlated to Ayurvedic entities. There is quite a bit of difference in the botanical correlation, parts, and substitutes reported in the different scholarly works, particularly for Pṛṣṇiparṇī, and Agnimantha. For e.g., is Uraria picta the original intended Pṛṣṇiparṇī, as the Ayurvedic Formulary of India (AFI) stipulates or is it U. lagopoidiodes or Desmodium gangeticum as other scholars report? While AFI provides two botanical correlations to Agnimantha in its two editions, namely Premna integrifolia and Clerodendrum phlomidis, other scholars correlate it to other Premna and Clerodendrum species. Why has AFI provided stem bark and whole plant as substitutes for roots of DM? Are substitutes recommended by AFI only for ecological or practical convenience or is there an Ayurvedic or pharmacological explanation for the same? Aim: There are many species used in the name of Daśamūla,, in this article all the species are listed out to find the differences in the usage of the drugs. Materials and Methods: Ayurveda texts and lexicons along with the texts which have done correlation work were considered to arrive at a list of various species used as Dasmula. Results and Conclusion: Since neither the methodology nor the logic behind the correlation have been discussed in these scholarly works, including the AFI, the same is not available for analysis or scrutiny. Such a list as provided in this article can form an essential base for a much needed systematic approach at etymological analysis, botanical correlation, and further scientific work to establish legitimacy of substitutes

    2016-01-01

    This article sheds light on Maria Bandeira, the first female botanist to work at the Botanic Garden of Rio de Janeiro. She was active in the 1920s, but is absent from the historiography and little cited in the scientific literature. The significant number of plant, fungus, and lichen specimens she collected, her capacity to reach far-flung places, her extensive correspondence with foreign experts, and her studies at Sorbonne are all sources for the analysis of the way botany was practiced and the social networks at play in science at the time. The end of her scientific career, when she adopted a cloistered life with the Barefoot Carmelite nuns, can be interpreted variously, and partially explains why her contributions to Brazilian botany have been forgotten.

  5. Day residue and screen memory in Freud's dream of the botanical monograph.

    1988-01-01

    Freud's theory of dream construction allowed the censorship to intervene only when a repressed infantile wish emerged from the unconscious. In his (1899) paper on screen memories, however, he proposed a mechanism for the defensive displacement of current events as they are sorted for introduction into permanent memory. I suggest that Freud was actually describing the conflictual process through which the day residue of the dream is formed. Day residue and screen memory are closely related as elements of the dreamer's present and past experience displaced from his more central instinctual concerns. Freud's dream of the botanical monograph clearly illustrates this relation. Substituted day residues were matched in the dream with relatively innocuous memories of past events of similar cognitive and affective significance. By retracing the substitutions, one can see how a current conflict over Fliess's role in the writing of the dream book recapitulated a series of Freud's earlier conflicts concerning his father and the power of books.

  10. Microbiological decontamination of botanical raw materials and corresponding pharmaceutical products by irradiation

    International Nuclear Information System (INIS)

    Microbiological contamination typical of botanical raw materials used in the manufacture of pharmaceuticals decreases with the increasing level of processing, on going from flowers and leaves (104-108 CFU/g), to fruits and seeds (102-106 CFU/g), to liquid extracts (104-106 CFU/g), and to dry extracts (102-105 CFU/g). At the same time the resistivity of microflora to irradiation, expressed as a dose required for the first 90% reduction, increases along the same assortment as 2, 4, 5 and 5 kGy, respectively. This results in doses between 4 and 30 kGy required to treat typical contamination, or between 10 and 40 kGy for severe cases. The contamination of final products, phyto-therapeutic ointments (104-107 CFU/g), is relatively sensitive to irradiation (Dfirst90%red=1 kGy) and usually does not require doses higher than 8 kGy

    Full Text Available Juglans regia L. was the first exotic species of this genus to be cultivated at Peter the Great Botanical Garden of the V.L. Komarov Botanical Institute of RAS in Saint Petersburg – it was mentioned at M.M. Terekhovsky’s Catalogue in 1796. Firstly it was cultivated indoors. It was tested by E.L. Regel as early as in 1871 but unsuccessfully. It has been cultivated trustworthy outdoors since 1914. It was seriously frost damaging during the 20th century in cold winters with temperature below -25 oC, such as in 1955/56, 1968/69, 1978/79, аnd 1984/85. The winter of 1986/87 with absolute minimum temperature -34,7oC was very unfavourable, and many trees died after it. At present, the winter hardiness has increased with the warming of the climate. There are no frost damages at all or they are small and insignificant. The largest trees now reach 19 m high and 31 cm of trunk diameter in the age of 67 years old. The majority of trees produce fruits. Twenty trees of modern collection represent the five generations. The visible increasing of adaptation abilities is observed starting with the fifth generation. The trees of the fifth generation are good looking single-trunked trees without frost damages. Since 2014 they have been producing fruits, and subsequently this is possible to obtain plants of the sixth generation. Apparently the specimens of the fifth and the next generations are of special value to test at areas outside of the city to promote the distribution of the walnut in cultivation.

    Full Text Available ABSTRACTKnowledge of soil characteristics in areas where activities related to the environment are developed, such as Porto Alegre Botanical Garden (JB-PoA, is a fundamental condition for the sustainable use of this natural resource. The objective of this study was to characterize, classify and evaluate some issues about soil formation in Porto Alegre Botanical Garden, as well as relate their distribution on the landscape according to environmental characteristics. For the morphological description and collecting samples four profiles were selected (P1 to P4, located in the summit-shoulder transition, backslope, footslope and toeslope, respectively. Granulometric distribution of the P1 and P3 profiles indicated sharp textural gradient, with presence of textural and "plânico" B horizons, respectively, according to Brazilian System of Soil Classification. There is predominance of low values of pH, and low base saturation, with exception of P4, indicating probable deposition of solution material at this area. The Fed/Fes relationship was greater in the profile located in the summit-shoulder transition (P1, indicating higher weathering. The Feo/Fed relationship increased in P3 and P4 profiles, indicating greater participation of iron oxides of low crystallinity in reducing environment. The occurrence of some pedogenic processes may be inferred, like lessivage in P1 (Ultic Hapludalf, due to clay skins and higher values of fine clay:total clay relationship in subsurface; ferrolysis and gleization, by low pH value and high Feo/Fed relationship in E and EB horizons of P3 (Oxyaquic Hapludalf, being the last also present in P4 (Humaqueptic Endoaquent, indicating gleization occurrence.

Materials and methods: LCS101 preparations were tested for batch-to-batch consistency using high-performance liquid chromatography. T-cell activation was quantified in murine spleen cells using 3H-thymidine incorporation, and cytokine production analyzed with enzyme-linked immunosorbent assay. Natural killer cell activity was tested on human blood cells using flow cytometry, and cytotoxicity measured by 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide and apoptosis using a FACSCalibur. Effects on interferon-γ production in fluorouracil/doxorubicin-treated mice were tested with enzyme-linked immunosorbent assay. Results: High-performance liquid chromatography analysis demonstrated batch-to-batch consistency. T-cell proliferation was increased, and a dose-dependent activation of natural killer cells and macrophage tumor necrosis factor-α secretion were observed with LCS101 treatment. Interferon-γ levels, reduced following fluorouracil treatment, were corrected in treated animals. No toxicity or compromised treatment outcomes were associated with LCS101 exposure. Conclusions: LCS101 demonstrated significant effects on a number of immune processes. Further research is needed in order to understand the molecular immunomodulatory pathways affected by this compound, as well as clinical implications for treatment.

    1988-01-01

    Bulk (elemental composition, IR, CP/MAS 13C NMR) and molecular (GC-MS) analyses have been performed on a series of ambers and resins derived from different locations (Dominican Republic, Philippines, Canada, Israel, New Zealand, Chile) having diverse botanical affinities (Araucariaceae, Hymenaea) and variable age (from Holocene to Early Cretaceous). No major differences have been observed from the elemental composition and the spectroscopic data; however, the molecular analyses of the solvent extractable fraction show that a specific mixture of components is present in each sample. These are mainly diterpenoid products that in general are also found abundantly in the higher plants from which the ambers and resins originate. Nevertheless, a direct relationship between major terpenoid constituents in fossil resins and precursor plant materials can only be established for the younger samples. Irrespective of the geographical or botanical origin of the ambers and resins, several common age-dependent molecular transformation trends can be recognized: (1) progressive loss of olefinic bonds (especially those located in exocyclic positions), (2) decrease of functionalized products, and (3) increasing proportion of aromatized components. However, even in the samples of older age (Cretaceous) the degree of aromatization is very low when compared with that of other higher-plant related materials such as fossilized woods or low rank coals. This indicates that maturation must involve essentially olefin polymerization processes instead of extensive aromatization. ?? 1988.

    Full Text Available The aim of this study was to evaluate the composition of 36 honey samples of 4 different botanical origins (acacia, sun flower, tilia and honeydew from the North East region of Romania. An inductively coupled plasma-mass spectrometry (ICP-MS method was used to determine 27 elements in honey (Ag, Al, As, Ba, Be, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga, K, Li, Mg, Mn, Na, Ni, Pb, Rb, Se, Sr, Tl, U, V and Zn. We would like to achieve the following goal: to demonstrate that the qualitative and quantitative multi-element composition determination of honey can be used as a suitable tool to classify honey according to its botanical origin. The principal component analysis allowed the reduction of the 27 variables to 2 principal components which explained 74% of the total variance. The dominant elements which were strongly associated with the principal component were K, Mg and Ca. Discriminant models obtained for each kind of botanical honey confirmed that the differentiation of honeys according to their botanical origin was mainly based on multi-element composition. A correct classification of all samples was achieved with the exception of 11.1% of honeydew honeys.

    2016-07-01

    Arthropods are dangerous vectors of agents of deadly diseases, which may hit as epidemics or pandemics in the increasing world population of humans and animals. Among them, ticks transmit more pathogen species than any other group of blood-feeding arthropods worldwide. Thus, the effective and eco-friendly control of tick vectors in a constantly changing environment is a crucial challenge. A number of novel routes have been attempted to prevent and control tick-borne diseases, including the development of (i) vaccines against viruses vectored by ticks; (ii) pheromone-based control tools, with special reference to the "lure and kill" techniques; (iii) biological control programmes relying on ticks' natural enemies and pathogens; and (iv) the integrated pest management practices aimed at reducing tick interactions with livestock. However, the extensive employment of acaricides and tick repellents still remains the two most effective and ready-to-use strategies. Unfortunately, the first one is limited by the rapid development of resistance in ticks, as well as by serious environmental concerns. On the other hand, the exploitation of plants as sources of effective tick repellents is often promising. Here, we reviewed current knowledge concerning the effectiveness of plant extracts as acaricides or repellents against tick vectors of public health importance, with special reference to Ixodes ricinus, Ixodes persulcatus, Amblyomma cajennense, Haemaphysalis bispinosa, Haemaphysalis longicornis, Hyalomma anatolicum, Hyalomma marginatum rufipes, Rhipicephalus appendiculatus, Rhipicephalus (Boophilus) microplus, Rhipicephalus pulchellus, Rhipicephalus sanguineus and Rhipicephalus turanicus. Eighty-three plant species from 35 botanical families were selected. The most frequent botanical families exploited as sources of acaricides and repellents against ticks were Asteraceae (15 % of the selected studies), Fabaceae (9 %), Lamiaceae (10 %), Meliaceae (5 %), Solanaceae (6

    Full Text Available Delphinium sergii Wissjul. is an endemic of eastern coast of Black Sea. It is listed in Red book of Ukraine with conservation status “vulnerable” (Didukh 2009. It grows mainly in eastern part of Ukraine in nature and is not typical for the Kyiv region. It is a perennial plant with bright blue flowers. The individuals of this specie are cultivated in the M.M. Gryshko National Botanical Garden during last 15 years. The results of the study of ontogenetic development and morphological diversity show that D. sergii is characterized by heterophylly and common morphological variability of leaf blade. The correlation of degree between leaf blade dissection and their formation and age was established. Dissected leaves are found to be “older” while with entire laminas – “younger”. Formation of different leaves in individuals of the same age states their dependence from lighting, soil moisture, crop density, genetic heterogeneity and plasticity of individuals in different conditions of growth. We observed a difference in terms of passing through ontogenetic stages among the individuals too. Our investigation established that the individuals of D. sergii ex situ can accelerate the ontogenetic development and reach the generative stage for just 2 years. The juvenile period in some individuals may last for just one growing season. It is noted that under the unfavorable factors (thickened crops, drought, and shading development of D. sergii individuals became slower. This species can be reproduced both by seed and vegetative. Propagation by seeds is the main way for distribution of these plants. Vegetative reproduction could be realized by particulation of individuals at g and ss stages. In Кyiv region D. sergii is blooming in June-July. Delphinium is well known as such representing the “bee-flowers syndrome”. According to our observations the main pollinators of D. sergii in conditions of our botanical garden were Bombus pascuorum (Scopoli

    Full Text Available Field trials were conducted during 2009 and 2010 rainy season to assess the efficacy of leaf extract of some botanicals for production of watermelon (Citrillus lanatus in Southern Guinea Savanna Nigeria. The treatments consisted of leaf extracts from 3 botanicals: Bush tea (Hyptis suaveolens, Moringa (Moringa oleifera and Pawpaw (Carica papaya and one synthetic insecticide Labdacyalothrin (karate. The experiment was laid in a Randomized Complete Block Design (RCBD and replicated 3 times to form fifteen plots. The results showed that, there was significant effect among the different botanicals used on all the parameters assessed except on the vinelength of watermelon, at various stages of growth in both years. Application of leaf extract of pawpaw gave better performance in all the parameters assessed when compared to the other botanicals in both years. Application of karate produced the best results in both years; while poor result were obtained from the control plots. Application of pawpaw leaf extract conferred high protection on the fruit when compared to other botanicals, which is statistically similar with result of karate in both 2009 and 2010 cropping season. Pawpaw leaf extracts appears to be a better botanical option in watermelon production.

    Shatavari-a famous Ayurveda materia medica used mainly as a tonic for women-is distributed in health food products all over the world. The Ayurvedic Pharmacopoeia of India identifies the botanical origin of shatavari as the tuberous root of Asparagus racemosus. We recently investigated by DNA analysis the botanical origin of shatavari products on the Japanese market. The results suggested that their botanical origin was Asparagus; however, species identification was difficult. In this study, we analyzed steroidal saponins, including those specific to this plant, in these products and confirmed their origin as A. racemosus. Next, alkaloid analyses of an authentic A. racemosus plant and these products were performed, because several papers have reported the isolation of a pyrrolo[1,2-a]azepine alkaloid, asparagamine A, from this plant. Our results suggest that neither plant material nor products contained asparagamine A. It has been pointed out that Stemona plants are sometimes mistaken for shatavari, because their tuberous roots have a similar shape to that of A. racemosus, and pyrrolo[1,2-a]azepine alkaloids are thought to be Stemona-specific. These data strongly suggest that A. racemosus does not contain asparagamine A, and that previous isolation of asparagamine A from materials claimed as originating from A. racemosus was likely caused by misidentification of Stemona plants as A. racemosus.

    The Chinese crude drug Qiang-hua was listed as an alias of Du-hua in Shen-nong-ben-cao-jing, an herbal journal written during the Han Dynasty, China. Du-hua and Qiang-hua are recognized as different herbs in China these days; the main botanical origin of Du-hua is Angelica spp. and that of Qiang-hua is Notopterygium spp., of the family Umbelliferae. To make clear the botanical origins of Du-hua and Qiang-hua in ancient China, the authors made a herbological study. The findings were as follows: the name of Qiang-hua was given to the genuine Du-hua, which is produced in Qiang Province, an ancient province located in northwest China; the botanical origin of Qiang-hua is presumed to be Notopterygium incisum Ting ex H.T. Chang and N. forbesii Boissieu based on both the morphology and habitat written in ancient herbal journals. Both species are prescribed as having the plant origin of Qiang-hua in the present Chinese Pharmacopoeia. Therefore, we concluded that Du-hua and Qiang-hua were essentially the same drug, and were originally derived from the Notopterygium species in ancient China.

    2016-09-01

    The adoption of exotic plants by indigenous herbivores in the region of introduction can be influenced by numerous factors. A botanical garden in Western Siberia was used to test various hypotheses on the adaptation of indigenous phyllophagous insects to exotic plants invasions, focusing on two feeding guilds, external leaf chewers and leaf miners. A total of 150 indigenous and exotic woody plant species were surveyed for insect damage, abundance and species richness. First, exotic woody plants were much less damaged by chewers and leaf miners than native plants, and the leaf miners' species richness was much lower on exotic than native plants. Second, exotic woody plants having a congeneric species in the region of introduction were more damaged by chewers and hosted a more abundant and species-rich community of leaf miners than plants without native congeneric species. Third, damage by chewers significantly increased with the frequency of planting of exotic host plants outside the botanical garden, and leaf miners' abundance and species richness significantly increased with residence time in the garden. Finally, no significant relationship was found between insect damage or abundance and the origin of the exotic plants. Besides the ecological implications of the results, this study also illustrates the potential of botanical gardens to test ecological hypotheses on biological invasions and insect-plant interactions on a large set of plant species.

    Shankhpushpi is a cognition boosting traditional ayurvedic brain supplement. Convolvulus pluricaulis (Convolvulaceae), Evolvulus alsinoides (Convolvulaceae), Clitoria ternatea (Papilionaceae), and Canscora decussata (Gentianaceae) are botanical claimants of Shankhpushpi. This investigation is to focus the identification of the compound based on biological marker differentiation of four botanical claimants of Shankhpushpi for their antioxidant evaluation on thin layer chromatography (TLC) by 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. A rapid TLC-DPPH method was developed to identify and differentiate four botanical claimants of Shankhpushpi in terms of presence of β-carotene, rutin, scopoletin, chlorogenic acid, and mangiferin. C. pluricaulis shows presence of scopoletin; E. alsinoides shows presence of β-carotene, scopoletin, and chlorogenic acid; C. ternatea shows presence of β-carotene, scopoletin, and rutin; and C. decussata shows presence of β-carotene, scopoletin, and mangiferin. The order, they followed, based on their antioxidant potential is β-carotene < mangiferin < rutin < scopoletin < chlorogenic acid. Antioxidants are attributed for their beneficial role in age-related cognition decline. The proposed method provides an edge in terms of identification and quantification of antioxidant constituents in a multi-component system. This method may also provide application for identification of correct plant sources used in the name of Shankhpushpi in marketed ayurvedic formulation, food supplement, and extracts. PMID:23662279

    The Paddar Valley, historically known as Sapphire Valley situated in Kishtwar district, is a prime landmark in the Jammu region of J&K state and is known for its rich cultural and plant diversity because of diverse habitats such as rivers, streams, meadows and steep mountain slopes. The area is located in the dry temperate region comprising typical vegetation which disappears completely on the eastern slopes, dominated by a variety of economical species which play an important role in the rural life. The inhabitants are dependent on plant resources for food, fuel, timber, shelter, fodder/forage, household articles and traditional medicines in treating diseases like malaria, cancer, gastro-intestinal ailments, etc. This paper deals with the observations on traditional therapeutic application by the inhabitants of Paddar Valley. The ethno-botanical information on medicinal plants would not only be useful in conservation of traditional cultures and biodiversity but also community health care and drug development. Exploration survey in Paddar Valley has revealed that people collect and sell these medicinal species through local intermediaries / contractors to earn their livelihood. But the scientific cultivation and appropriate post-harvest management would improve employment opportunity and income of local farmers in the region.

    Natural pesticides have attracted substantial interest due to the increase in organic agriculture and enhanced attention to environmental pollution. Plant Growth Promoting Bacteria (PGPB) are applied for both disease control and growth enhancement; PGPBs are known to elicit Induced Systemic Response (ISR) in plants. However, less is known about the effect of botanical pesticides, such as the azadirachtin-containing neem extracts, on plant metabolism. This study aimed to investigate the effects of foliar application of the above-mentioned natural pesticides on the metabolic profiling of tomato. Leaf application of Bacillus subtilis fostered Induced Systemic Resistance (ISR) in treated plants via the Jasmonic acid pathway, and enhanced production of secondary metabolites such as flavonoids, phytoalexins and auxins. Changes in sterols and terpenes, as well as an increase in glucosinolates were also observed. Interestingly, azadirachtin-treated tomatoes also showed an increase in ISR and our results revealed that most of the enriched metabolites are shared with a B. subtilis treatment, suggesting conserved biochemical responses. These (un)expected findings indicate that plants are not insensitive to application of natural pesticide and while Azadirachtin is applied as a direct pesticide, it also stimulates a defense response in tomatoes very similar to B. subtilis induced ISR.

    Full Text Available AbstractCarbon nanofibers (CNF with diameters of 20–130 nm with different morphologies were obtained from a botanical hydrocarbon: Turpentine oil, using ferrocene as catalyst source and sulfur as a promoter by simple spray pyrolysis method at 1,000 °C. The influence of sulfur concentration on the morphology of the carbon nanofibers was investigated. SEM, TEM, Raman, TGA/DTA, and BET surface area were employed to characterize the as-prepared samples. TEM analysis confirms that as-prepared CNFs have a very sharp tip, bamboo shape, open end, hemispherical cap, pipe like morphology, and metal particle trapped inside the wide hollow core. It is observed that sulfur plays an important role to promote or inhibit the CNF growth. Addition of sulfur to the solution of ferrocene and turpentine oil mixture was found to be very effective in promoting the growth of CNF. Without addition of sulfur, carbonaceous product was very less and mainly soot was formed. At high concentration of sulfur inhibit the growth of CNFs. Hence the yield of CNFs was optimized for a given sulfur concentration.

    The millions of plant specimens that have been collected and stored in Chinese herbaria over the past ~110 years have recently been digitized and geo-referenced. Here we use this unique collection data set for species distribution modeling exercise aiming at mapping & explaining the botanical richness; delineating China’s phytogeographical regions and investigating the environmental drivers of the dissimilarity patterns. We modeled distributions of 6,828 woody plants using MaxEnt and remove the collection bias using null model. The continental China was divided into different phytogeographical regions based on the dissimilarity patterns. An ordination and Getis-Ord Gi* hotspot spatial statistics were used to analysis the environmental drivers of the dissimilarity patterns. We found that the annual precipitation and temperature stability were responsible for observed species diversity. The mechanisms causing dissimilarity pattern seems differ among biogeographical regions. The identified environmental drivers of the dissimilarity patterns for southeast, southwest, northwest and northeast are annual precipitation, topographic & temperature stability, water deficit and temperature instability, respectively. For effective conservation of China’s plant diversity, identifying the historical refuge and protection of high diversity areas in each of the identified floristic regions and their subdivisions will be essential.

    As part of a collaboration with the National Institutes of Health's Office of Dietary Supplements and the Food and Drug Administration's Center for Drug Evaluation and Research, the National Institute of Standards and Technology has developed Standard Reference Material (SRM) 3274 Botanical Oils Containing Omega-3 and Omega-6 Fatty Acids and SRM 3275 Omega-3 and Omega-6 Fatty Acids in Fish Oil. SRM 3274 consists of one ampoule of each of four seed oils (3274-1 Borage (Borago officinalis), 3274-2 Evening Primrose (Oenothera biennis), 3274-3 Flax (Linium usitatissimum), and 3274-4 Perilla (Perilla frutescens)), and SRM 3275 consists of two ampoules of each of three fish oils (3275-1 a concentrate high in docosahexaenoic acid, 3275-2 an anchovy oil high in docosahexaenoic acid and eicosapentaenoic acid, and 3275-3 a concentrate containing 60% long-chain omega-3 fatty acids). Each oil has certified and reference mass fraction values for up to 20 fatty acids. The fatty acid mass fraction values are based on results from analyses using gas chromatography with flame ionization detection (GC-FID) and mass spectrometry (GC/MS). These SRMs will complement other reference materials currently available with mass fractions for similar analytes and are part of a series of SRMs being developed for dietary supplements.

We randomized patients into a double blind, 18 month trial. Mixed effects models were used to compare trends over time in serum lipids. No significant differences were observed between the three groups: All three treatment groups exhibited similar meaningful improvement in the lipid profile at 9 and 18 months. When all groups were combined, these treatments significantly reduced total and LDL-cholesterol and triglycerides, increased HDL-cholesterol, and improved the atherogenic index. All improvements observed at 9 months persisted at 18 months (P<0.001 verses baseline. Conclusion. Marine and botanical oils may be useful treatment for rheumatoid arthritis patients who are at increased risk for cardiovascular disease compared to the general population.

    Full Text Available Nostochopsis spp. are edible and rare cyanobacteria which form thick mucilaginous colonies, 0.1-8 cm in size, attached on the rocks or cobbles in transparent shallow streams or rivers. They are classified in the Order Nostocales, Family Hapalosiphonaceae. The objective of this study was to investigate the colonial growth, pigments and quality of water in the ponds at 3 glass houses in the Queen Sirikit Botanic Garden, Chiang Mai Province in which these cyanobacteria were growing during April-June 2012. The three glass houses were; the Aquatic house, the Bromeliad house and Orchids and Fern house. Ten colonies from each sampling site were measured once a week. The average increase in colonial size was found to be 0.17±0.06, 0.30±0.08 and 0.15±0.08 cm/week respectively. Chlorophyll, phycocyanin, allophycocyanin and carotenoid were highest in the samples from Aquatic house as 16.22±4.28, 11.95±8.55, 73.62±4.07 and 12.70±1.54 mg/g.dw, respectively. These cyanobacteria grew at 22-30°C, pH 6.17-8.75 and conductivity 112-171 µs/cm. The water quality was clean-moderate and in oligo-mesotrophic status.

    The Asian citrus psyllid, Diaphorina citri Kuwayama, is the insect vector of the pathogen causing huanglongbing. We selected three botanical oils to evaluate behavioral activity against D. citri. In laboratory olfactometer assays, fir oil was repellent to D. citri females, while litsea and citronella oils elicited no response from D. citri females. In choice settling experiments, D. citri settled almost completely on control plants rather than on plants treated with fir oil at a 9.5 mg/day release rate. Therefore, we conducted field trials to determine if fir oil reduced D. citri densities in citrus groves. We found no repellency of D. citri from sweet orange resets that were treated with fir oil dispensers releasing 10.4 g/day/tree as compared with control plots. However, we found a two-week decrease in populations of D. citri as compared with controls when the deployment rate of these dispensers was doubled. Our results suggest that treatment of citrus with fir oil may have limited activity as a stand-alone management tool for D. citri and would require integration with other management practices.

    The Asian citrus psyllid (ACP) Diaphorina citri Kuwayama vectors pathogens that cause huanglongbing (HLB) or citrus greening devastating and economically important disease present in most citrus growing regions. Young citrus shoots are required for psyllid reproduction and development. During winter citrus trees produce little or no new growth. Overwintering adults reproduce in spring on newly emerging shoots also attractive to other pests and beneficial insects. Botanicals and relatively selective insecticides could help to conserve beneficial insects and reduce pest resistance to insecticides. Sprays of Azadirachtin (Neem), Tropane (Datura), Spirotetramat, Spinetoram, and broad-spectrum Imidacloprid were evaluated to control ACP in spring and summer on 10-year-old "Kinow" Citrus reticulata Blanco trees producing new growth. Psyllid populations were high averaging 5-9 nymphs or adults per sample before treatment application. Nymphs or adults were significantly reduced to 0.5-1.5 per sample in all treatments for 3 weeks, average 61%-83% reduction. No significant reduction in ladybeetles Adalia bipunctata, Aneglei scardoni, Cheilomenes sexmaculata, and Coccinella septempunctata was observed. Syrphids, spiders and green lacewings were reduced in treated trees except with Tropane. Studies are warranted to assess impact of these predators on ACP and interaction with insecticides. Observed reduction in ACP populations may not be enough considering its reproductive potential and role in the spread of HLB. Follow-up sprays may be required to achieve additional suppression using rotations of different insecticides. PMID:25205398

    The understanding of epilepsy has progressed since its earliest impression as a disease associated with paranormal and superstitious beliefs. Landmark advances have been made in deciphering the pathophysiological substrates involved in the disease process, and treatment advances have contributed significantly to ameliorating the seizures. However, disease-modifying agents are yet to be discovered. Ayurveda is a system of medicine that stresses a holistic approach to disease, and treatment is focused on disease modification and symptom management. Herbs form the core of Ayurveda medicine; though many of them have been studied for their anticonvulsant activity, very few actually mention the reference of these herbs in Ayurveda literature. Other therapeutic interventions used in Ayurveda are relatively unexplored, and future research will need to focus on this. The current manuscript briefly discusses the understanding of epilepsy as per Ayurveda and reviews herbs that have been studied for their anticonvulsant activity mentioned in Ayurveda literature. This article is part of a Special Issue entitled "Botanicals for Epilepsy". PMID:26141933

    Full Text Available Ethno botanical studies reveal that the indigenous knowledge of a community is a key player in the identification of medicinal plants and such plants have beenoften tested by generations of indigenous people. In the present investigation, the hydro-alcoholic extracts of leaves of Azadirachta indica (Neemand Swertia chirayta(Chirayta were assessed for anti-helminthic potential against helminths (earthworms were used as model at 10, 50 and 100 mg/ml. No anti-helminthic potential was observed at 10 mg/ml of dose of the hydro-alcoholic extracts of Swertia chirayta. The hydro-alcoholic extracts of both the plants showed significant anti-helminthicactivity on selected worms at higher doses. Hydro-alcoholic leaves extracts of Azadirachta indica (Neemwasfound to be more active as compared tohydro-alcoholic whole plant extracts of Swertia chirayta(Chirayta at concentration of 100 mg/ml. It was observed that with the variation in dose, the death time and paralysis time of the worms’ decreases. The results indicated that extracts possessed dose dependent anti-helminthic activity. The results were compared toPiperazine citrate and Albendazole (15 mg/ml. The hydro-alcoholic extracts demonstrated paralysis as well as death ofworms in a less time in comparison to the standard drugs. The anti-helminthic activity of the extracts indicates the presence of active principle responsible for anti-helminthic activity.

    A novel botanic biopreservative was successfully prepared by the combination of the bamboo leaves extracts and ebony extracts, designated as ebony-bamboo leaves complex extracts (EBLCE), whose antimicrobial activity was assessed according to an inhibition zone method against 10 common pathogenic and spoilage microorganisms. It was found that EBLCE was more effective from all the chosen microorganisms, as compared by potassium sorbate. Due to its excellent antimicrobial activity, and some additional properties like edibility, safety and economy, EBLCE was selected for further study to evaluate the efficacy in prolonging shelf life and improving the quality of peeled Penaeus vannamei during storage at 4 °C, based on periodical microbiological, chemical and sensory analysis. As a result, EBLCE was observed to prevent spoilage of peeled P. vannamei efficiently as reflected by a distinct decrease in total viable count, pH and total volatile basic nitrogen, as well as a slower decline in the sensory evaluation scores. Therefore, a prolonged shelf life of 16 days was obtained for EBLCE pre-treated peeled shrimps with comparison of 6 days for the control group, demonstrating EBLCE as a promising alternative for preserving food.

    Interviews were conducted with 100 adults (27 men, 73 women) enrolled in a prepaid medical health plan to investigate their use of botanical remedies. They were asked which of 50 listed herbs they or members of their families had used for health purposes and with what effect; which of 60 listed health problems they had treated with home remedies; and what additional home remedies or alternative health care resources they had used. Over 100 different home remedies were identified, with most considered effective. Individual respondents used from 0 to 33 herbal and plant remedies (Md = 7), some of which have toxic properties. A remedy was reported for almost every health problem listed. Substances most frequently used were aloe vera, honey, peppermint, garlic, eucalyptus, and rose hips; health problems most frequently treated were burns, colds, indigestion, insect bites, insomnia, rashes. Persons who were married, from larger households, of higher socioeconomic status, who had consulted alternative healers, or who had patronized health food stores tended to use home remedies more than their counterparts. Implications for further evaluation of self-care practices are discussed. PMID:1891620

    Prolonged stress, whether a result of mental/emotional upset or due to physical factors such as malnutrition, surgery, chemical exposure, excessive exercise, sleep deprivation, or a host of other environmental causes, results in predictable systemic effects. The systemic effects of stress include increased levels of stress hormones such as cortisol, a decline in certain aspects of immune system function such as natural killer cell cytotoxicity or secretory-IgA levels, and a disruption of gastrointestinal microflora balance. These systemic changes might be a substantial contributor to many of the stress-associated declines in health. Based on human and animal research, it appears a variety of nutritional and botanical substances - such as adaptogenic herbs, specific vitamins including ascorbic acid, vitamins B1 and B6, the coenzyme forms of vitamin B5 (pantethine) and B12 (methylcobalamin), the amino acid tyrosine, and other nutrients such as lipoic acid, phosphatidylserine, and plant sterol/sterolin combinations - may allow individuals to sustain an adaptive response and minimize some of the systemic effects of stress.

    By adopting inductively coupled plasma mass spectrometry (ICP-MS) combined with chemometric analysis technology, 23 kinds of minerals in four kinds of characteristic honey derived from Yunnan province were analyzed. The result showed that 21 kinds of mineral elements, namely Na, Mg, K, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Sb, Ba, Tl and Pb, have significant differences among different varieties of honey. The results of principal component analysis (PCA) showed that the cumulative variance contribution rate of the first four main components reached 77.74%, seven kinds of elements (Mg, Ca, Mn, Co, Sr, Cd, Ba) from the first main component contained most of the honey information. Through the stepwise discriminant analysis, seven kinds of elements (Mg, K, Ca, Cr, Mn, Sr, Pb) were filtered. out and used to establish the discriminant function model, and the correct classification rates of the proposed model reached 90% and 86.7%, respectively, which showed elements contents could be effectively indicators to discriminate the four kinds characteristic honey in southern Yunnan Province. In view of all the honey samples were harvested from apiaries located at south Yunnan Province where have similar climate, soil and other environment conditions, the differences of the mineral elements contents for the honey samples mainly due to their corresponding nectariferous plant. Therefore, it is feasible to identify honey botanical source through the differences of mineral elements.

  13. Mutual Transformation of Colonial and Imperial Botanizing? The Intimate yet Remote Collaboration in Colonial Korea.

    Argument Mutuality in "contact zones" has been emphasized in cross-cultural knowledge interaction in re-evaluating power dynamics between centers and peripheries and in showing the hybridity of modern science. This paper proposes an analytical pause on this attempt to better invalidate centers by paying serious attention to the limits of mutuality in transcultural knowledge interaction imposed by asymmetries of power. An unusually reciprocal interaction between a Japanese forester, Ishidoya Tsutomu (1891-1958), at the colonial forestry department, and his Korean subordinate Chung Tyaihyon (1883-1971) is chosen to highlight an inescapable asymmetry induced by the imperial power structure. Ishidoya, positioning himself as a settler expert, as opposed to a scientist in Tokyo, pursued localized knowledge in growing interaction with Chung, resulting in Ishidoya's career change as a herbalist focusing on traditional medicine and Chung's leadership in Korean-only botanizing. However, their mutual transformations, limited by asymmetric constraints on their choices, did not unsettle the imperial power structure or the centrality of centers. PMID:27171892

    Full Text Available Annona is a genus belongs to Annonaceae family, consisting of numerous species that produce edible fruit. Four species namely A. glabra, A. montana, A. muricata and A. squamosa collections of Purwodadi Botanic Garden were recorded for its flowering and fruiting times, since November 2010 to April 2013. The data were scored and complemented with climate data (temperature, rainfall intensity, humidity then analyzed using multiple linear regression analysis. The result showed that humidity was the most affected climate factors on the flowering and fruiting times of those species. Specifically, rainfall intensity (0-550 mm affected to Annona muricata, temperature (25,56-28,33°C and humidity (66,83-85,02% to Annona squamosa, and humidity to A. glabra (71,62-85,02% and A. montana (71,62 to 82,94 % as well. Flowering time of A. glabra occurs three times a year in wet and dry, and fruiting occurs twice a year in the same month. Annona muricata is flowering throughout the year and fruiting twice a year in wet. A. montana and A. squamosa recorded one a year during the wet month.

    Rheumatoid arthritis (RA) is a chronic, systemic autoimmune inflammatory disorder that causes permanent disability and mortality to approximately 1 to 100 people in the world. Patients with RA not only suffer from pain, stiffness, swelling, and loss of function in their joints, but also have a higher risk of cardiovascular disease and lymphoma. Typically prescribed medications, including pain-relieving drugs, nonsteroidal anti-inflammatory drugs (NSAID), and disease-modifying antirheumatic drugs, can help to relieve pain, reduce inflammation and slow the course of disease progression in RA patients. However, the general effectiveness of the drugs has been far from satisfactory. Other therapeutic modalities like TNF-alpha (TNF-α) inhibitors and interleukin-1 receptor antagonists targeting precise pathways within the immune system are expensive and may be associated with serious side effects. Recently, botanical medicines have become popular as alternative remedies as they are believed to be efficacious, safe and have over a thousand years experience in treating patients. In this review, we will summarize recent evidence for pharmacological effects of herbs including Black cohosh, Angelica sinensis, Licorice, Tripterygium wilfordii, Centella asiatica, and Urtica dioica. Scientific research has demonstrated that these herbs have strong anti-inflammatory and anti-arthritic effects. A wide range of phytochemicals including phenolic acids, phenylpropanoid ester, triterpene glycosides, phthalide, flavonoids, triterpenoid saponin, diterpene and triterpene have been isolated and demonstrated to be responsible for the biological effects of the herbs. Understanding the mechanisms of action of the herbs may provide new treatment opportunities for RA patients.

    Humification conditions and humus status parameters in arboretum soils of the Moscow State University botanical garden on the Vorob'evy Hills have been studied. Although microbiological activity is reduced, the warm and mild climate in the city, the eutrophication of soils (due to atmospheric fallouts and dissolution of construction waste inclusions), the retention of plant waste on the soil surface, and the presence of abundant primary destructors (mesofauna) have resulted in the formation of organic matter with specific characteristics. During the 60 years that have elapsed since the arboretum establishment, soils with a high content (up to 10-14%) of humate humus (CHA/CFA > 1) characterized by a higher degree of humification than in the control soils under herbaceous vegetation have been developed in the area. Large reserves of organic carbon have been noted not only in the upper 30-cm-thick soil layer, but also in the 1-m-thick layer due to organic matter of buried and technogenic horizons.

    Extensive evidence has demonstrated that psychological stress has detrimental effects on psychological health, cognitive function, and ultimately well-being. While stressful events are a significant cause of psychopathology, most individuals exposed to adversity maintain normal psychological functioning. The mechanisms underlying such resilience are poorly understood, and there is an urgent need to identify and target these mechanisms to promote resilience under stressful events. Botanicals have been used throughout history to treat various medical conditions; however, the development of botanical compounds into potential preventative and therapeutic agents in studies promoting brain health is hindered by the fact that most orally consumed botanicals are extensively metabolized during absorption and/or by post-absorptive xenobiotic metabolism. Therefore, the primary objective of this review article is to provide recommendations for developing natural compounds as novel therapeutic strategies to promote resilience in susceptible subjects. The development of botanical polyphenols to ultimately attenuate mood disorders and cognitive impairment will rely on understanding (1) the absorption and bioavailability of botanical polyphenols with emphasis on flavan-3-ols, (2) the characterization of tissue-specific accumulation of biologically available polyphenols and their mechanisms of action in the brain, and eventually (3) the characterization of biologically available polyphenol metabolites in mechanisms associated with the promotion of resilience against mood disorders and cognitive impairment in response to stress. We also summarize exciting new lines of investigation about the role of botanicals such as polyphenols in the promotion of cognitive and psychological resilience. This information will provide a strategical framework for the future development of botanicals as therapeutic agents to promote resilience, ultimately preventing and/or therapeutically treating

    The concentrations of Fe, Mn, Al, Zn, Pb, Ni, Cr, and As were measured in soils and leaves from 21 plant species growing on hills near the Beijing Steel Factory(BSF) and 17 plant species in the Beijing Botanical Garden(BBG). The results showed that soils from BSF were Zn contaminated according to the threshold of natural background of China. There was a metal contamination of the soils by Ni,and Cr in BSF comparing with those in BBG. The comparison between concentrations of metals in leaves from both sites indicated that, in general, accumulation of metals in the leaves of the same species was significantly different between the two sites. Even within the same locality each species accumulation of metals was significantly variable. The study aimed to screen landscape plants for the capacity to clean-up toxic metals in soils, and developed an overall metal accumulation index(MAI) for leaves and then categorized the MAI that can be applied broadly in the selection of species in polluted areas. To do this, the spectrum of MAI values were divided into four classes:strongly accumulated(SA or grade Ⅰ), moderately accumulated(MA or grade Ⅱ), intermediately accumulated( IA or grade Ⅲ), and weakly accumulated(WA or grade Ⅳ). The results showed that elemental association between Fe, Al, Ni, and As was generally highly correlated with each other in the sampling sites. This may suggest their common biochemical characteristics. Generally, those species containing strong and moderate accumulation in both sites are considered including Vitex negundo, Broussonetia papyrifera, Ulmus pumila, and Rubia cordifolia. At BSF and other industrial sites with a similar ecosystem, strong and moderate accumulation species include Sophora japonica, Ampelopsis aconitifolia var. glabra, Platycladus orientalis, Wikstroemia chamaedaphne, Cleistogenes squarro sa, Grewia biloba, and in BBG, in addition Setaria viridis, Cotinus coggygria, Lespedeza floribunda, Rhamnus parvifolia, Lespedeza

    Full Text Available Conservation areas with the objective for collection and exchange plant materials have been speculated as weed bank for surrounding areas. Objective of this study was to identify and characterize ruderal invasive weeds in the Bogor Botanic Gardens (BBG. Observations were conducted in all vak (collection blocks in the BBG in order to identify the weeds species, determine their invasiveness, dominance and distribution. Weeds associations with host plants were observed. Current weed control program and data of dead trees collection were analyzed in relevant to weed. Distribution of weeds outside BBG was observed by transects method following river and road directions. Results showed that there were seven invasive weeds, i.e., Cecropia adenopus (Cecropiaceae, Cissus nodosa Blume (Vitaceae, Cissus sicyoides Blume (Vitaceae, Dioscorea bulbifera L. (Dioscoreaceae, Ficus elastica Roxb. (Moraceae, Mikania micrantha H.B.K. (Asteraceae and Paraserianthes falcataria (L. Nielsen (Fabaceae. These seven weeds species invaded 41 out of 215 plant families in BBG. Six species of weeds, i.e., C. adenopus, C. nodosa Blume., C. sicyoides Blume., D. bulbifera L., M. micrantha H.B.K. and P. falcataria (L. Nielsen, were introduced as BBG collections for the first time while the F. elastica Roxb was considered as native. It is most likely that the weeds dispersal agents are the wind, birds, bats, visitors, and waters. All of these weeds existed in surrounding areas outside BBG. Given the detrimental impact of invasive weeds on the plant collection in BBG, it is necessary to develop long–term comprehensive control measures both inside and neighboring areas by involving other government authorities beyond BBG.

    Full Text Available In 1796, Thomas Hardwicke travelled through northern India between what is now Fatehgarh in Uttar Pradesh and Srinagar in Uttarakhand. Hardwicke collected and described plants encountered and had many of the plants illustrated from life. He published an account of the journey in 1799 including a list of plant species. I review the names validated in the original paper, and also those published subsequently by Sir James Edward Smith and William Roxburgh based partly or wholly on the material or drawings acquired by Hardwicke on the journey to Srinagar. The large collection of Hardwicke plant drawings now held in the British Library, and a smaller set in the Botany Library of the Natural History Museum, are considered in relation to the application and typification of plant names related to Hardwicke’s botanical exploration in India. The names of seven plant species were validly published in the 1799 paper (Androsace rotundifolia Hardw., Ficus laminosa Hardw., Justicia thyrsiformis Roxb. ex Hardw., Linum trigynum Roxb. ex Hardw., Lonicera quinquelocularis Hardw., Salvia integrifolia Roxb. ex Hardw. and Volkameria bicolor Hardw., plus one new combination (Echites antidysentericus (L.

    Outdoor thermal comfort studies have mainly examined the perception of local residents, and there has been little work on how those conditions are perceived differently by tourists, especially tourists of diverse origins. This issue is important because it will improve the application of thermal indices in predicting the thermal perception of tourists. This study aims to compare the differences in thermal perception and preferences between local and overseas visitors to the Royal Botanic Garden (RBG) in Melbourne during summer. An 8-day survey was conducted in February 2014 at four sites in the garden (n = 2198), including 2 days with maximum temperature exceeding 40 °C. The survey results were compared with data from four weather stations adjacent to the survey locations. One survey location, `Fern Gully', has a misting system and visitors perceived the Fern Gully to be cooler than other survey locations. As the apparent temperature exceeded 32.4 °C, visitors perceived the environment as being `warm' or `hot'. At `hot' conditions, 36.8 % of European visitors voted for no change to the thermal conditions, which is considerably higher than the response from Australian visitors (12.2 %) and Chinese visitors (7.5 %). Study results suggest that overseas tourists have different comfort perception and preferences compared to local Australians in hot weather based at least in part on expectations. Understanding the differences in visitors' thermal perception is important to improve the garden design. It can also lead to better tour planning and marketing to potential visitors from different countries.

    This study reports on the socio-demographic and locality factors that influence ethnobiological knowledge in three communities of Zapotec indigenous people of the Isthmus of Tehuantepec, Mexico. It uses local botanical nomenclature as a proxy for general ethnobiological knowledge. In each of these communities (one urban and two rural), 100 adult men were interviewed aided with a field herbarium. Fifty had a background in farming, and 50 worked in the secondary or tertiary sector as their main economic activity, totaling 300 interviews. Using a field herbarium with samples of 30 common and rare wild regional species, we documented visual recognition, knowledge of the local life form, generic and specific names and uses (five knowledge levels measuring knowledge depth). The relationship between sociodemographic variables and knowledge was analyzed with simple correlations. Differences between the three communities and the five knowledge levels were then evaluated with a discriminant analysis. A general linear analysis identified factors and covariables that influenced the observed differences. Differences between the groups with different economic activities were estimated with a t-test for independent samples. Most of the relationships found between sociodemographic variables and plant knowledge were expected: age and rurality were positively related with knowledge and years of formal schooling was negatively related. However, the somewhat less rural site had more traditional knowledge due to local circumstances. The general linear model explained 70-77% of the variation, a high value. It showed that economic activity was by far the most important factor influencing knowledge, by a factor of five. The interaction of locality and economic activity followed. The discriminant analysis assigned interviewees correctly to their localities in 94% of the cases, strengthening the evidence for intracultural variation. Both sociodemographic and historic intracultural

    Rheumatoid arthritis (RA) is a chronic, systemic autoimmune inflammatory disorder that causes permanent disability and mortality to approximately 1 to 100 people in the world. Patients with RA not only suffer from pain, stiffness, swelling, and loss of function in their joints, but also have a higher risk of cardiovascular disease and lymphoma. Typically prescribed medications, including pain-relieving drugs, nonsteroidal anti-inflammatory drugs (NSAID), and disease-modifying antirheumatic drugs, can help to relieve pain, reduce inflammation and slow the course of disease progression in RA patients. However, the general effectiveness of the drugs has been far from satisfactory. Other therapeutic modalities like TNF-alpha (TNF-α) inhibitors and interleukin-1 receptor antagonists targeting precise pathways within the immune system are expensive and may be associated with serious side effects. Recently, botanical medicines have become popular as alternative remedies as they are believed to be efficacious, safe and have over a thousand years experience in treating patients. In this review, we will summarize recent evidence for pharmacological effects of herbs including Black cohosh, Angelica sinensis, Licorice, Tripterygium wilfordii, Centella asiatica, and Urtica dioica. Scientific research has demonstrated that these herbs have strong anti-inflammatory and anti-arthritic effects. A wide range of phytochemicals including phenolic acids, phenylpropanoid ester, triterpene glycosides, phthalide, flavonoids, triterpenoid saponin, diterpene and triterpene have been isolated and demonstrated to be responsible for the biological effects of the herbs. Understanding the mechanisms of action of the herbs may provide new treatment opportunities for RA patients. PMID:22700248

  5. Identification and analysis of the active phytochemicals from the anti-cancer botanical extract Bezielle.

    Directory of Open Access Journals (Sweden)

    Vivian Chen

    Full Text Available Bezielle is a botanical extract that has selective anti-tumor activity, and has shown a promising efficacy in the early phases of clinical testing. Bezielle inhibits mitochondrial respiration and induces reactive oxygen species (ROS in mitochondria of tumor cells but not in non-transformed cells. The generation of high ROS in tumor cells leads to heavy DNA damage and hyper-activation of PARP, followed by the inhibition of glycolysis. Bezielle therefore belongs to a group of drugs that target tumor cell mitochondria, but its cytotoxicity involves inhibition of both cellular energy producing pathways. We found that the cytotoxic activity of the Bezielle extract in vitro co-purified with a defined fraction containing multiple flavonoids. We have isolated several of these Bezielle flavonoids, and examined their possible roles in the selective anti-tumor cytotoxicity of Bezielle. Our results support the hypothesis that a major Scutellaria flavonoid, scutellarein, possesses many if not all of the biologically relevant properties of the total extract. Like Bezielle, scutellarein induced increasing levels of ROS of mitochondrial origin, progressive DNA damage, protein oxidation, depletion of reduced glutathione and ATP, and suppression of both OXPHOS and glycolysis. Like Bezielle, scutellarein was selectively cytotoxic towards cancer cells. Carthamidin, a flavonone found in Bezielle, also induced DNA damage and oxidative cell death. Two well known plant flavonoids, apigenin and luteolin, had limited and not selective cytotoxicity that did not depend on their pro-oxidant activities. We also provide evidence that the cytotoxicity of scutellarein was increased when other Bezielle flavonoids, not necessarily highly cytotoxic or selective on their own, were present. This indicates that the activity of total Bezielle extract might depend on a combination of several different compounds present within it.

    1.Few studies describing the pharmacokinetic properties of chlorogenic acid (CA) and corydaline (CRD) which are marker compounds of a new prokinetic botanical agent, DA-9701, have been reported. The aim of the present study is to evaluate the pharmacokinetic properties CA and CRD following intravenous and oral administration of pure CA (1-8 mg/kg) or CRD (1.1-4.5 mg/kg) and their equivalent dose of DA-9701 to rats. 2.  Dose-proportional AUC and dose-independent clearance (10.3-12.1 ml/min/kg) of CA were observed following its administration. Oral administration of CA as DA-9701 did not influence the oral pharmacokinetic parameters of CA. Incomplete absorption of CA, its decomposition in the gastrointestinal tract, and/or pre-systemic metabolism resulted in extremely low oral bioavailability (F) of CA (0.478-0.899%). 3.  CRD showed greater dose-normalized AUC in the higher dose group than that in lower dose group(s) after its administration due to saturation of its metabolism via decreased non-renal clearance (by 51.3%) and first-pass extraction. As a result, the F of CRD following 4.5 mg/kg oral CRD (21.1%) was considerably greater than those of the lower dose groups (9.10 and 13.8%). However, oral administration of CRD as DA-9701 showed linear pharmacokinetics as a result of increased AUC and F in lower-dose groups (by 182% and 78.5%, respectively) compared to those of pure CRD. The greater oral AUC of CRD for DA-9701 than for pure CRD could be due to decreased hepatic and/or GI first-pass extraction of CRD by other components in DA-9701.

  8. Contamination from polycyclic aromatic hydrocarbons (PAHs) in the soil of a botanic garden localized next to a former manufacturing gas plant in Palermo (Italy)

    International Nuclear Information System (INIS)

    The Botanical Garden lies within the city of Palermo, a few meters away from one of the largest unused Manufacturing Gas Plant in Sicily. The total concentrations of PAHs (23 compounds) in the soil of Botanical Garden ranged from 947 to 18,072 μg/kg. The wide range of PAH concentrations (RSD = 84%) found in the soil samples indicates heterogeneous levels of contamination in the area and this can be explained by considering the different tree distributions which prevents the homogeneous deposition of pollutants on the soil. Soils collected in the Botanical Garden generally showed the highest PAH concentrations, being almost 2-3 times higher than the concentration samples obtained in the urban reference sites and about 20 times higher than those in the rural stations. The total PAH concentrations, in the Botanical Garden soil, resulted higher than the maximum concentrations allowed by the Italian legislation for the green areas. Perylene, was found in all the stations. From a careful study of the isomeric ratios, we can hypothesize that the soils of the Botanical Garden are mainly affected by localized MGP particulate deposition, suggesting that the partitioning between organic matter and PAHs is not the dominant process in the soils with higher organic matter content.

    Herbal medicines and botanicals have long been used as sole or additional medical aids worldwide. Currently, billions of dollars are spent on botanicals and related products, but minimal regulation exists regarding their purity, integrity, and efficacy. Cases of adulteration and contamination have led to severe illness and even death in some cases. Identifying the plant material in botanicals and phytomedicines using organoleptic means or through microscopic observation of plant parts is not trivial, and plants are often misidentified. Recently, DNA-based methods have been applied to these products because DNA is not changed by growth conditions unlike the chemical constituents of many active pharmaceutical agents. In recent years, DNA barcoding methods, which are used to identify species diversity in the Tree of Life, have been also applied to botanicals and plant-derived dietary supplements. In this review, we recount the history of DNA-based methods for identification of botanicals and discuss some of the difficulties in defining a specific bar code or codes to use. In addition, we describe how next generation sequencing technologies have enabled new techniques that can be applied to identifying these products with greater authority and resolution. Lastly, we present case histories where dietary supplements, decoctions, and other products have been shown to contain materials other than the main ingredient stipulated on the label. We conclude that there is a fundamental need for greater quality control in this industry, which if not self-imposed, that may result from legislation. PMID:25856442

    2010-01-01

    AOAC Official Method 991.31 for the determination of aflatoxins (AFs; sum of aflatoxins B1, B2, G1, and G2) in corn, raw peanuts, and peanut butter by using immunoaffinity column cleanup with LC has been modified and applied to the determination of AFs in botanical roots. The modifications were necessary to improve the performance of the method for matrixes beyond corn and peanuts. The extraction solvent was changed from a mixture of methanol and water to acetonitrile and water. The accuracy, repeatability, and reproducibility characteristics of this method were determined. Replicates of 10 test portions of each powdered root (black cohosh, echinacea, ginger, ginseng, kava kava, and valerian) at each spiking level (AFs at 0, 2, 4, 8, and 16 ng/g) were analyzed on 3 separate days. Test portions were extracted with acetonitrile-water (84 + 16, v/v), and the extracts were centrifuged, diluted with phosphate-buffered saline, filtered, and applied to an immunoaffinity column containing antibodies specific for AFs. After the column was washed with water, the toxins were eluted from the column with methanol and quantified by HPLC with fluorescence detection. All test materials except kava kava were found to contain AF at < 0.1 ng/g. Kava kava was naturally contaminated with AFs at 0.5 ng/g. Average within-day and between-days recoveries of AFs from botanical roots ranged from 88 to 112 and from 86 to 118%, respectively. Total RSD values for within-day and between-days repeatability ranged from 1.4 to 15.9%. HorRat values were < 0.4 for all of the matrixes examined. The modified AOAC Official Method 991.31 was found to be applicable to an analysis of the six botanical roots. PMID:20334179

  11. Horizontal transfer of diatomaceous earth and botanical insecticides in the common bed bug, Cimex lectularius L.; hemiptera: cimicidae.

    Yasmin Akhtar

    Full Text Available BACKGROUND: Horizontal transfer of insecticide occurs when insects contact or ingest an insecticide, return to an aggregation or a nest, and transfer the insecticide to other conspecific insects through contact. This phenomenon has been reported in a number of insects including social insects, however it has not been reported in bed bugs. Since horizontal transfer can facilitate the spread of insecticide into hard to reach spaces, it could contribute greatly to the management of these public health pests. METHODOLOGY/RESULTS: To demonstrate horizontal transfer of diatomaceous earth and botanical insecticides in C. lectularius, an exposed (donor bed bug, following a 10-minute acquisition period, was placed with unexposed (recipient bed bugs. Mortality data clearly demonstrates that diatomaceous earth (DE 51 was actively transferred from a single exposed bug to unexposed bugs in a concentration dependent manner. LC50 values varied from 24.4 mg at 48 h to 5.1 mg at 216 h when a single exposed bed bug was placed with 5 unexposed bed bugs. LT50 values also exhibited a concentration response. LT50 values varied from 1.8 days to 8.4 days when a 'donor' bug exposed to 20 and 5 mg of dust respectively was placed with 5 'recipient' bugs. Dust was also actively transferred from adult bed bugs to the nymphs. In addition we observed horizontal transfer of botanical insecticides including neem, ryania, and rotenone to varying degrees. CONCLUSION/SIGNIFICANCE: Our data clearly demonstrate horizontal transfer of diatomaceous earth and botanical insecticides in the common bed bug, C. lectularius. Use of a fluorescent dust provided visual confirmation that contaminated bed bugs transfer dust to untreated bed bugs in harborage. This result is important because bedbugs live in hard-to-reach places and interaction between conspecifics can be exploited for delivery and dissemination of management products directed at this public health pest.

    Lentil, one of the oldest legumes was Investigated for diversity based on botanical descriptors, total seed proteins,isozymes and random amplified polymorphic DNA (RAPD) markers. About one fourth of accessions were heterogeneous for botanical descriptors and a seed protein profile. The germplaem collected from the province of Baluchistan revealed the prevalence of indigenous landraces as high diversity was observed for all of the techniques. Diversity explored through various techniques revealed validity Irrespective of the sample size or geographic pattern, RAPD being the best choice for Investigating both inter- and intra-accession variation In lentil. Although all of the techniques were able to resolve genetic diversity In lentil, isozymes and seed proteins gave low levels of genetic diversity, suggesting that more investigation into isozymes of specific proteins is required. RAPD is the best option for determining inter- and Intra-accession variation, and will be required to extend germplasme and primers to continue the study of botanical descriptors.

    Background Genomic research depends upon access to DNA or tissue collected and preserved according to high-quality standards. At present, the collections in most natural history museums do not sufficiently address these standards, making them often hard or impossible to use for whole-genome sequencing or transcriptomics. In response to these challenges, natural history museums, herbaria, botanical gardens and other stakeholders have started to build high-quality biodiversity biobanks. Unfortunately, information about these collections remains fragmented, scattered and largely inaccessible. Without a central registry or even an overview of relevant institutions, it is difficult and time-consuming to locate the needed samples. Scope The Global Genome Biodiversity Network (GGBN) was created to fill this vacuum by establishing a one-stop access point for locating samples meeting quality standards for genome-scale applications, while complying with national and international legislations and conventions. Increased accessibility to genomic samples will further genomic research and development, conserve genetic resources, help train the next generation of genome researchers and raise the visibility of biodiversity collections. Additionally, the availability of a data-sharing platform will facilitate identification of gaps in the collections, thereby empowering targeted sampling efforts, increasing the breadth and depth of preservation of genetic diversity. The GGBN is rapidly growing and currently has 41 members. The GGBN covers all branches of the Tree of Life, except humans, but here the focus is on a pilot project with emphasis on ‘harvesting’ the Tree of Life for vascular plant taxa to enable genome-level studies. Conclusion While current efforts are centred on getting the existing samples of all GGBN members online, a pilot project, GGI-Gardens, has been launched as proof of concept. Over the next 6 years GGI-Gardens aims to add to the GGBN high-quality genetic

    The performance of a clinical trial for pharmaceutical agents is usually undertaken only after there is likely benefit demonstrated from the use of the putative agent. The consideration of botanical products as pharmaceutical agents must similarly go through a rigorous evaluation process. The present work reviews the recently published Phase II study evaluating the effectiveness of black cohosh and red clover in a randomized trial with conjugated equine estradiol/medroxyprogesterone acetate and placebo for the treatment of menopausal symptoms. We analyze the possible reasons why this study failed to show benefit for either botanical product in reducing menopause-related vasomotor symptoms. PMID:21034798

    A simplified sample preparation method in combination with gas chromatography-triple-quadrupole mass spectrometry (GC-MS/MS) analysis was developed and validated for the simultaneous determination of 227 pesticides in green tea, ginseng, gingko leaves, saw palmetto, spearmint, and black pepper samples. The botanical samples were hydrated with water and extracted with acetonitrile, magnesium sulfate, and sodium chloride. The acetonitrile extract was cleaned up using solid phase extraction with carbon-coated alumina/primary-secondary amine with or without C18. Recovery studies using matrix blanks fortified with pesticides at concentrations of 10, 25, 100, and 500 μg/kg resulted in average recoveries of 70-99% and relative standard deviation of 5-13% for all tested botanicals except for black pepper, for which lower recoveries of fortified pesticides were observed. Matrix-matched standard calibration curves revealed good linearity (r(2) > 0.99) across a wide concentration range (1-1000 μg/L). Nine commercially available tea and 23 ginseng samples were analyzed using this method. Results revealed 36 pesticides were detected in the 9 tea samples at concentrations of 2-3500 μg/kg and 61 pesticides were detected in the 23 ginseng samples at concentrations of 1-12500 μg/kg.

    The lipophilic character of five vehicles (or co-vehicles): diethylhexylmaleate, dimethicone, light mineral oil, octyldodecanol and oleyl alcohol and eight botanical oils: Aloe vera oil, coconut oil, extra virgin olive oil, grape leaf oil, grape seed oil, hazelnut oil, jojoba oil and safflower oil was determined by partitioning esters of p-hydroxybenzoic acid (parabens) between them and phosphate buffer (pH 7.4). The results were compared to those obtained with 1-octanol. The most lipophilic effects were observed with octyldodecanol and oleyl alcohol for the vehicles (or co-vehicles), coconut oil, jojoba oil and safflower oil for botanical oils. Light mineral oil showed the least lipophilic effect. With butylparaben, it was observed that oleyl alcohol, octyldodecanol, coconut oil and jojoba oil were 0.94, 0.91, 0.74 and 0.68 times as lipophilic as 1-octanol respectively. The study indicates that octyldodecanol and oleyl alcohol could be good substitutes for 1-octanol in partition coefficient determination. The estimated permeability coefficients of the parabens suggest that octyldodecanol, oleyl alcohol, coconut oil and jojoba oil could be potential dermal permeation enhancers.

    In recent years, the potential of Fourier-transform infrared spectroscopy coupled with different chemometric tools in food analysis has been established. This technique is rapid, low cost, and reliable and requires little sample preparation. In this work, 130 Serbian unifloral honey samples (linden, acacia, and sunflower types) were analyzed using attenuated total reflectance infrared spectroscopy (ATR-IR). For each spectrum, 64 scans were recorded in wavenumbers between 4000 and 500 cm-1 and at a spectral resolution of 4 cm-1. These spectra were analyzed using principal component analysis (PCA), and calculated principal components were then used for support vector machine (SVM) training. In this way, the pattern-recognition tool is obtained for building a classification model for determining the botanical origin of honey. The PCA was used to analyze results and to see if the separation between groups of different types of honeys exists. Using the SVM, the classification model was built and classification errors were acquired. It has been observed that this technique is adequate for determining the botanical origin of honey with a success rate of 98.6%. Based on these results, it can be concluded that this technique offers many possibilities for future rapid qualitative analysis of honey.

    Fruit foragers are known to use spatial memory to relocate fruit, yet it is unclear how they manage to find fruit in the first place. In this study, we investigated whether chimpanzees (Pan troglodytes verus) in the Taï National Park make use of fruiting synchrony, the simultaneous emergence of fruit in trees of the same species, which can be used together with sensory cues, such as sight and smell, to discover fruit. We conducted observations of inspections, the visual checking of fruit availability in trees, and focused our analyses on inspections of empty trees, so to say "mistakes". Learning from their "mistakes", we found that chimpanzees had expectations of finding fruit days before feeding on it and significantly increased inspection activity after tasting the first fruit. Neither the duration of feeding nor density of fruit-bearing trees in the territory could account for the variation in inspection activity, which suggests chimpanzees did not simply develop a taste for specific fruit on which they had fed frequently. Instead, inspection activity was predicted by a botanical feature-the level of synchrony in fruit production of encountered trees. We conclude that chimpanzees make use of the synchronous emergence of rainforest fruits during daily foraging and base their expectations of finding fruit on a combination of botanical knowledge founded on the success rates of fruit discovery, and a categorization of fruit species. Our results provide new insights into the variety of food-finding strategies employed by primates and the adaptive value of categorization capacities.

    Objective: To evaluate the ovicidal activity of different botanical oil formulations againstHelicoverpa armigera and Spodoptera litura. Methods: Different botanical oils were formulated with different ratio to evaluate the ovicidal activity against H. armigera and S. litura at 5, 10, 15 and 20μl/L concentrations. Results: All the oil formulations showed the ovicidal activity against H. armigera and S. litura. The maximum ovicidal actvity of 76.74 and 69.36% was noticed at 20μl/L concentration in formulation 3 PONNEEM. Formulation 4 Pongam oil showed lower ovicidal activity of 31.34 and 24.76% against H. armigera and S. litura respectively. Among the formulations, PONNEEM exhibited statistically superior ovicidal activity against both insect pests. Conclusions: the present study clearly showed PONNEEM as a pontenial biopesticide to control the egg stage of economically important pests of H. armigera and S. litura. This is the first report for the ovicidal activity of PONNEEM against these two insect pests.

For each spectrum, 64 scans were recorded in wavenumbers between 4000 and 500 cm−1 and at a spectral resolution of 4 cm−1. These spectra were analyzed using principal component analysis (PCA), and calculated principal components were then used for support vector machine (SVM) training. In this way, the pattern-recognition tool is obtained for building a classification model for determining the botanical origin of honey. The PCA was used to analyze results and to see if the separation between groups of different types of honeys exists. Using the SVM, the classification model was built and classification errors were acquired. It has been observed that this technique is adequate for determining the botanical origin of honey with a success rate of 98.6%. Based on these results, it can be concluded that this technique offers many possibilities for future rapid qualitative analysis of honey. (paper)

    Full Text Available Laboratory bioassays were carried out for evaluating the efficacy of certain plant materials including Nicotine, Thymol, Menthol, Caffeine and Camphor as molluscicides against the brown garden snail, Eobania vermiculata using the topical application method. The obtained results proved that Nicotine and Thymol were the most promising from the molluscicidal point of view with LD50 204.02 and 551.20g/snail for the two materials, respectively. The effects of sublethal doses (LD25 and LD50 of the most potent materials, Thymol and Nicotine, on the oxygen consumption of E. vermiculata snails after 1, 7 and 15 days post treatment were evaluated. Results indicated that only snails treated with LD50 Thymol showed significant decrease in their oxygen uptake; while all the other treatments stimulated significant increase in the oxygen consumption along the three periods of estimation. This stimulation was most pronounced with the low sublethal doses of the both examined botanical molluscicides. The succession of time post exposure did not enable the treated snails to eliminate the adverse effects of the applied materials. Depending on the results of the current investigation, we can conclude that the both examined botanical materials, Thymol and Nicotine, are effective in killing the agricultural pest E. vermiculata but further studies are needed to evaluate the efficacy of these materials as safe and economic molluscicides in the field.

    Josef Armin Knapp (1843-1899) as Austrian botanist was interested in development of botanical knowledge of Austro-Hungarian Monarchy--his maternal country. Monarchy, during the long regency of emperor Franz Josef I, was multinational, very much diversified geographically territory. This large empire had included, among others, such countries as present Austria, Hungary, Slovakia, Croatia, Ukraine, Romania and the southern part of present Poland--previously known as Galicia. J. A. Knapp was interested in studying these parts of empire which were considered peripheries and less-known. It seems to have met the requirements of science, economy and administration of Vienna. J. A. Knapp in his large floristic researches had included explorations of considerable part of the Monarchy and had left an interesting scientific legacy. His research papers were results of botanical explorations in selected areas of the Monarchy--area of Nitra (currently a city in Slovakia), Slavonia (presently a land in Croatia) and Galicia (the historical area in the south of Poland). This article refers to the botanical journey of J. A. Knapp in Galicia in summer 1868. The main purpose of his journey was to visit and explore selected places in Galicia--the surroundings of Jaslo and Sanok towns and some specific areas within the Bieszczady Mountains, which are part of the Carpathians Mountains. Botanical researches in the Bieszczady Mountains provided by J. A. Knapp can be considered nowadays as very important and pioneering in that area. In the second part of XIX century this area was highly populated and the observed anthropogenic pressure applied to the nature was strong. Now, the area is considered a very valuable natural territory--since 1973 it has been occupied by the Bieszczady National Park--one of Polish national parks. J. A. Knapp had spent more than two months in Galicia thanks to the great hospitality of Polish people, especially botanists: A. Rehmann, I. R. Czerwiakowski, W. Jab

    Full Text Available Background: Several studies have analyzed the functions of foods and dietary constituents in the dynamics of alcohol metabolism. However, few studies have reported the function of dietary fibers in the dynamics of alcohol metabolism. Objective: We assessed the effects of botanical foods that contain dietary fibers on alcohol metabolism. Methods: The ability of the water-insoluble fraction (WIF of 18 kinds of botanical foods to maintain 15% (v/v ethanol solution was examined using easily handled filtration. A simple linear regression analysis was performed to examine the correlation between the filtered volumes and blood ethanol concentration (BEC in F344 rats 4 h after the ingestion of 4.0 g/kg of ethanol following dosage of 2.5% (w/v WIF of the experimental botanical foods. Furthermore, the supernatant (6.3 Brix; water-soluble fraction and precipitate (WIF of tomato, with a strong ethanol-maintaining ability, were obtained and BEC and the residual gastric ethanol in rats were determined 2 h after the administration of 4.0 g/kg of ethanol and the individuals fractions. Results: The filtered volumes of dropped ethanol solutions containing all the botanical foods tested except green peas were decreased compared with the ethanol solution without WIF (control. There was a significant correlation between the filtered volumes and blood ethanol concentration (BEC. There was no significant difference in the residual gastric ethanol between controls and the supernatant group; however, it was increased significantly in the WIF group than in controls or the supernatant group. Consistent with this, BEC reached a similar level in controls and the supernatant group but significantly decreased in the WIF group compared with controls or the supernatant group. Conclusions: These findings suggest that WIFs of botanical foods, which are mostly water-insoluble dietary fibers, possess the ability to absorb ethanol-containing solutions, and this ability correlates

    A new detection method has been applied to study the penetration depth of low-energyheavy ions in botanic samples. Highly oriented pyrolytic graphite (HOPG) pieces were placed behind the target samples with certain thickness to receive energetic penetrated ions during the irradiation. After irradiation, statistic number density of protrusion-like damage induced by energetic penetrated ions can be ob tained through scanning tunneling microscope (STM) observation on the surfaces of HOPG. The results of test indicate that the detection limit can be as low as 1.0× 109 protrusions/em2. With the method, the penetration depth of at least 60μm can be detected in kidney bean slices irradiated by N+ ions with dose of 0.3-3× 1017ions/cm2.

    Quality by design (QbD) concept is a paradigm for the improvement of botanical injection quality control. In this work, water precipitation process for the manufacturing of Xueshuantong injection, a botanical injection made from Notoginseng Radix et Rhizoma, was optimized using a design space approach as a sample. Saponin recovery and total saponin purity (TSP) in supernatant were identified as the critical quality attributes (CQAs) of water precipitation using a risk assessment for all the processes of Xueshuantong injection. An Ishikawa diagram and experiments of fractional factorial design were applied to determine critical process parameters (CPPs). Dry matter content of concentrated extract (DMCC), amount of water added (AWA), and stirring speed (SS) were identified as CPPs. Box-Behnken designed experiments were carried out to develop models between CPPs and process CQAs. Determination coefficients were higher than 0.86 for all the models. High TSP in supernatant can be obtained when DMCC is low and SS is high. Saponin recoveries decreased as DMCC increased. Incomplete collection of supernatant was the main reason for the loss of saponins. Design space was calculated using a Monte-Carlo simulation method with acceptable probability of 0.90. Recommended normal operation region are located in DMCC of 0.38-0.41 g/g, AWA of 3.7-4.9 g/g, and SS of 280-350 rpm, with a probability more than 0.919 to attain CQA criteria. Verification experiment results showed that operating DMCC, SS, and AWA within design space can attain CQA criteria with high probability.

  1. Evaluation of estrogenic activity of licorice species in comparison with hops used in botanicals for menopausal symptoms.

    Directory of Open Access Journals (Sweden)

    Atieh Hajirahimkhan

    Full Text Available The increased cancer risk associated with hormone therapies has encouraged many women to seek non-hormonal alternatives including botanical supplements such as hops (Humulus lupulus and licorice (Glycyrrhiza spec. to manage menopausal symptoms. Previous studies have shown estrogenic properties for hops, likely due to the presence of 8-prenylnarigenin, and chemopreventive effects mainly attributed to xanthohumol. Similarly, a combination of estrogenic and chemopreventive properties has been reported for various Glycyrrhiza species. The major goal of the current study was to evaluate the potential estrogenic effects of three licorice species (Glycyrrhiza glabra, G. uralensis, and G. inflata in comparison with hops. Extracts of Glycyrrhiza species and spent hops induced estrogen responsive alkaline phosphatase activity in endometrial cancer cells, estrogen responsive element (ERE-luciferase in MCF-7 cells, and Tff1 mRNA in T47D cells. The estrogenic activity decreased in the order H. lupulus > G. uralensis > G. inflata > G. glabra. Liquiritigenin was found to be the principle phytoestrogen of the licorice extracts; however, it exhibited lower estrogenic effects compared to 8-prenylnaringenin in functional assays. Isoliquiritigenin, the precursor chalcone of liquiritigenin, demonstrated significant estrogenic activities while xanthohumol, a metabolic precursor of 8-prenylnaringenin, was not estrogenic. Liquiritigenin showed ERβ selectivity in competitive binding assay and isoliquiritigenin was equipotent for ER subtypes. The estrogenic activity of isoliquiritigenin could be the result of its cyclization to liquiritigenin under physiological conditions. 8-Prenylnaringenin had nanomolar estrogenic potency without ER selectivity while xanthohumol did not bind ERs. These data demonstrated that Glycyrrhiza species with different contents of liquiritigenin have various levels of estrogenic activities, suggesting the importance of precise labeling of

    A genome-wide detection of phylogenetic signals by next generation sequencing (NGS) has recently emerged as a promising genomic approach for phylogenetic analysis of non-model organisms. Here we explored the use of a multiplexed shotgun sequencing method to assess the phylogenetic relationships of 18 Linum samples representing 16 species within four botanical sections of the flax genus Linum. The whole genome DNAs of 18 Linum samples were fragmented, tagged, and sequenced using an Illumina MiSeq. Acquired sequencing reads per sample were further separated into chloroplast, mitochondrial and nuclear sequence reads. SNP calls upon genome-specific sequence data sets revealed 6143 chloroplast, 2673 mitochondrial, and 19,562 nuclear SNPs. Phylogenetic analyses based on three-genome SNP data sets with and without missing observations showed congruent three-genome phylogenetic signals for four botanical sections of the Linum genus. Specifically, two major lineages showing a separation of Linum-Dasylinum sections and Linastrum-Syllinum sections were confirmed. The Linum section displayed three major branches representing two major evolutionary stages leading to cultivated flax. Cultivated flax and its immediate progenitor were formed as its own branch, genetically more closely related to L. decumbens and L. grandiflorum with chromosome count of eight, and distantly apart from six other species with chromosome count of nine. Five species of the Linastrum and Syllinum sections were genetically more distant from cultivated flax, but they appeared to be more closely related to each other, even with variable chromosome counts. These findings not only provide the first evidence of congruent three-genome phylogenetic pathways within the Linum genus, but also demonstrate the utility of the multiplexed shotgun sequencing in acquisition of three-genome phylogenetic signals of non-model organisms.

    The National Botanic Garden of Walse is the first national botanic garden to be built with a clear vision derived from the principles of sustainability laid down at the Rio Earth Summit. although the garden is embracing sustainability as its overall theme that is not our focus-merely how we go about our business. Sustainability at the Garden of Wales is based on a holistic approach within a social, political, economic, cultural, spiritual and environmental context. The garden offers a wide range of approaches to help people make new choices about their futures. It will be a flag-bearer for "preferred futures". The paper describes how the Garden of Wales is helping regenerate the region economically by adopting a preferred futures approach which involves envisioning a desired future then working back from there ("backcasting") in partnership with others to change the present in order to achieve that future. Examples covered include: Biotechnium (the world′s first Biosciences business incubator within a botanic garden); new partnership-based tourism products for Walse; local and regional product development and sourcing for retail outlets in the garden; and the creation of traditional healing and lifelong learning centres in the garden. Reference will also be made to: how the garden recycles water, deals with its effluent in a "Living Machine", generates its heat and power in a Biomass Boiler, runs its farms organically, uses slate waste as mulch, is creating genetic and global warming gardens, planning its demonstration organic and heritage vegetable gardens and biomass plantations. A broad outline will also be given of the scientific role of the garden and the role it will play in conserving the flora of Wales and West Atlantic Europe. A key theme of the paper is that through ideas generated in the paper that botanic gardens can and should help increase economic wealth, improve health and promote stable communities. It is how we map out our futures and set tough

    Plant use is an elusive issue in Paleolithic archaeology. Due to poor organic preservation in many sites, botanical material is not always present. The sediments in Schöningen, however, contain abundant botanical macro-remains like wood, fruits, seeds, and other parts of plants which offer the opportunity to reconstruct the local vegetation. Combined with palynological results, it is possible to reveal the full potential of this environment to hominins. Ethnobotanical studies of hunter-gatherer societies living in similar environments illustrate the importance of plants for subsistence purposes. The identified taxa from the archaeological horizons at Schöningen include a broad spectrum of potentially exploitable species that could be sources of food, raw material, and firewood.

    In all plant conservation, the priority is to maintain wild populations in situ (on site), which means that plants are conserved within their natural environment. Sometimes, as in the case of severely endangered Saintpaulia H. Wendl. (African violets), this is however, no sufficient. In that case, ex situ (off site) conservation in the form of live and in vitro collections and seed banks is necessary. In recent years, the role of botanic gardens in conservation and reintroduction of threatene...

    Increased fruit and vegetable consumption may protect against lung cancer, although epidemiologic findings are inconclusive. The authors prospectively examined associations between lung cancer risk and intakes of fruit, vegetables, and botanical subgroups in 472,081 participants aged 50-71 years in the National Institutes of Health (NIH)-AARP Diet and Health Study. Diet was assessed at baseline (1995-1996) with a 124-item dietary questionnaire. A total of 6,035 incident lung cancer cases were identified between 1995 and 2003. Total fruit and vegetable intake was unrelated to lung cancer risk in both men and women. Higher consumption of several botanical subgroups, however, was significantly inversely associated with risk, but only in men. For example, the relative risks of lung cancer among men in the highest versus lowest quintiles of intake of rosaceae, convolvulaceae, and umbelliferae were 0.82 (95% confidence interval (CI): 0.73, 0.91), 0.86 (95% CI: 0.75, 0.96), and 0.86 (95% CI: 0.78, 0.96), respectively; corresponding relative risks in women were 0.97 (95% CI: 0.85, 1.12), 0.95 (95% CI: 0.83, 1.09), and 0.92 (95% CI: 0.80, 1.06). These results provide support for a protective role of specific botanical subgroups of fruits and vegetables in lung cancer prevention in men, although the findings could also be due to residual confounding by smoking or chance.

  18. Volatile Compounds in Honey: A Review on Their Involvement in Aroma, Botanical Origin Determination and Potential Biomedical Activities

    Directory of Open Access Journals (Sweden)

    Christy E. Manyi-Loh

    2011-12-01

    Full Text Available Volatile organic compounds (VOCs in honey are obtained from diverse biosynthetic pathways and extracted by using various methods associated with varying degrees of selectivity and effectiveness. These compounds are grouped into chemical categories such as aldehyde, ketone, acid, alcohol, hydrocarbon, norisoprenoids, terpenes and benzene compounds and their derivatives, furan and pyran derivatives. They represent a fingerprint of a specific honey and therefore could be used to differentiate between monofloral honeys from different floral sources, thus providing valuable information concerning the honey’s botanical and geographical origin. However, only plant derived compounds and their metabolites (terpenes, norisoprenoids and benzene compounds and their derivatives must be employed to discriminate among floral origins of honey. Notwithstanding, many authors have reported different floral markers for honey of the same floral origin, consequently sensory analysis, in conjunction with analysis of VOCs could help to clear this ambiguity. Furthermore, VOCs influence honey’s aroma described as sweet, citrus, floral, almond, rancid, etc. Clearly, the contribution of a volatile compound to honey aroma is determined by its odor activity value. Elucidation of the aroma compounds along with floral origins of a particular honey can help to standardize its quality and avoid fraudulent labeling of the product. Although only present in low concentrations, VOCS could contribute to biomedical activities of honey, especially the antioxidant effect due to their natural radical scavenging potential.

    Full Text Available Pereskia bleo, a leafy cactus, is a medicinal plant native to West and South America and distributed in tropical and subtropical areas. It is traditionally used as a dietary vegetable, barrier hedge, water purifier, and insect repellant and for maintaining health, detoxification, prevention of cancer, and/or treatment of cancer, hypertension, diabetes, stomach ache, muscle pain, and inflammatory diseases such as dermatitis and rheumatism. The aim of this paper was to provide an up-to-date and comprehensive review of the botanical characteristics, traditional usage, phytochemistry, pharmacological activities, and safety of P. bleo. A literature search using MEDLINE (via PubMed, Science direct, Scopus and Google scholar and China Academic Journals Full-Text Database (CNKI and available eBooks and books in the National University of Singapore libraries in English and Chinese was conducted. The following keywords were used: Pereskia bleo, Pereskia panamensis, Pereskia corrugata, Rhodocacus corrugatus, Rhodocacus bleo, Cactus panamensis, Cactus bleo, Spinach cactus, wax rose, Perescia, and Chinese rose. This review revealed the association between the traditional usage of P. bleo and reported pharmacological properties in the literature. Further investigation on the pharmacological properties and phytoconstituents of P. bleo is warranted to further exploit its potentials as a source of novel therapeutic agents or lead compounds.

    2000-09-01

    The methane produced in peat soils can vary over the growing season due to variations in the supply of available substrate, the activity of the microbial community or changes in temperature. Our aim was to study how these factors regulate the methane production over the season from five different peat types of different botanical origin. Peat samples were collected on seven occasions between June and September. After each sampling, the peat soils were incubated at five different temperatures (7, 10, 15, 20 and 25 degrees C) without added substrate, or at 20 degrees C with added substrate (glucose, or H(2)/CO(2), or starch). Rates of methane production averaged over the season differed significantly (Pmethane production from each plant community varied significantly (Ptemperature, explains the seasonal variation in methane production. However, addition of saturating amounts of glucose, H(2)/CO(2) or starch at 20 degrees C significantly reduced the seasonal variation (Pmethane production in peat from the minerotrophic lawn, wet carpet and mud-bottom plant communities. This suggests that substrate supply (e.g. root exudates) for the micro-organisms also varied over the season at these sites. Seasonal variation in methane production rates was apparent in peat from the hummock and ombrotrophic lawn plant communities even after addition of substrates, suggesting that the active biomass of the anaerobic microbial populations at these sites was regulated by other factors than the ones studied.

  3. Phenological behaviour of desert plants in response to temperature change: a case study from turpan eremophytes botanical garden, northwest china

    International Nuclear Information System (INIS)

    The phenology of three genera of desert plants (viz., Calligonum L., Haloxylon L., and Tamarix L.) was investigated in response to temperature changes in Turpan. Eremophytes Botanical Garden The temperature was raised gradually from 1977 to 2006, while the phenophases of Calligonum L., Haloxylon L., and Tamarix L. genera were slowly and insignificantly changed in the study area. Their phenophase were similar and did not change significantly over the duration of the study except the beginning of flowering of the average of the three genera from 1977 to 1990 and 1991 to 2006, respectively. The summed temperature of the first four months was the major factor that affected the spring and flowering phenophases of the respective genera. The bud of Calligonum species was expanded during 1977 to 1990 and 1991 to 2006, the flower-buds in Tamarix species appeared during 1977 to 2006, the fruit setting of Haloxylon species started 1990 to 2006 and leaf discoloration of Tamarix species appeared during 1977 to 1990.

    Full Text Available The article discusses agro-botanical illustration of hand fans painting as an independent resource of visual information on the history of culture of introduction, distribution, species diversity and plant breeding. We have reviewed the history of the fan and the causes of widespread of fans and the respective painting plants. The article shows the different trends in the filing of a visual image in the fan art: from accurate, detailed drawing of the image, until smooth, blurred contours, made in the "boneless" or "acyclic" technique. On the example of pumpkins, lagenaria, soybeans, corn, flowers, namely asters and peonies we have shown various aspects of breeding and agronomic work for several centuries. The article uses the method of visual analysis as a tool for collection and analysis of data on breeding and introduction of a number of crops on the example of specific crops, particularly soybeans. The analysis includes a description of morphotypes, area of origin, distribution, physiology, individual characteristics, and insects found in the ecological niche. It is noted that visual analysis can be successfully applied in the study of varietal diversity of a number of flower crops: asters, peonies, chrysanthemums, and some fruits and vegetables

    Full Text Available – Fieldtrips can be considered as one of the three avenues through which science can be taught - through formal classroom teaching, practical work and field trips. An exposure trip at Bangkong Kahoy Valley Field Study Center was arranged for a class of BS Biology and BS Education students enrolled in Ecology Course. This approach purposefully transformed the usual exposure trip from being a casual site visit into a focused and productive learning experience. This transformation from exposure trip to a botanical expedition has exceeded the initial activity goals. Rather than a day off from learning, the time spent at the study center has been a meaningful opportunity to engage students in an active ecological research project while delivering valuable science content. Employing the descriptive survey design, the learning gains of the students were assessed and students were directed to do a guided reflection writing using the ORID Model of Focused Conversation. The learning gains and reflections of the students confirmed that students can collaboratively develop focused research questions, make meaning from a variety of sources, carry out a vegetation analysis and conduct surveys on socio-economic status, plant resource utilization and ecotourism assessment of the host community. As students prepared for their trip and synthesized their learning afterward, they were able to come up with very impressive and scientifically sound research outputs.

    Specialty maize genotypes viz. QPM (quality protein maize), Baby corn, Popcorn and Sweet corn, which are usually consumed in whole forms can be good supplements of phenolic antioxidants. Botanical fractions of these maize genotypes were analyzed to explore the distribution of free and bound phenolics. HPLC and ESI-MS/MS results indicated the presence of vanillic, syringic, p-hydroxybenzoic, caffeic, p-coumaric, ferulic and isoferulic acids along with cyanidin-3-O-glucoside, kaempferol and quercetin. Germs of maize samples contained significantly higher free phenolics than pericarps, whereas, pericarps contained 74-83% of bound ones. QPM and Popcorn contained only 3% free phenolics whereas, Baby corn and Sweet corn had 14-17%. Unlike in peroxide scavenging and reducing capacity, anti-radical capacity of free phenolics of germs was significantly higher than that of pericarps. Free phenolics contributed 0.2-1.65%, 2-5% and 42-49% in anti-radical, peroxide scavenging and reducing capacity, respectively. Among lipophilic tocochromanols γ-tocopherol was the most abundant isomer in the samples among which Sweet corn contained the most (84.2 μg/g). Data showed that specialty maize genotypes are rich sources of hydrophilic and lipophilic bioactives and are natural antioxidants. PMID:26868580

    2016-04-01

    Androgenic alopecia (AGA) is the most common type of hair loss in men, characterized by hair miniaturization, hairline recession, and vertex balding. It affects approximately 50% of men, negatively affecting self-esteem and sociability. Topical minoxidil formulations are approved up to a 5% concentration for men, but patient adherence to treatment is challenged by gradual results that may be perceived as a lack of initial benefit. Herbal extracts, which are also believed to promote healthier-looking hair, have a long history of use in hair care formulations. The safety and efficacy of a twice-daily regimen of 5% minoxidil foam used in combination with a novel botanical hair solution was evaluated in a 12-week, multicenter, single-arm, open label study in 56 subjects with mild to moderate AGA. Assessments included investigator ratings of improvement and subject self-ratings of satisfaction. Investigator ratings indicated significant improvement in scalp hair coverage and perception of overall treatment benefit in as early as 4 weeks (PAGA that also provides a high level of patient satisfaction, which may help promote patient adherence to long-term treatment.

    2001-09-01

    It was investigated whether the botanical drug combination Sinupret is able to modulate the resistance of mice to a respiratory tract infection with Sendai virus (Parainfluenza viridae) if given prophylactically to the animals. Three doses of Sinupret drops (SD) and Sinupret tablets (ST, p.o.), and two active controls, the chemical secretolytic ambroxol (p.o.) and the immunomodulator Muramyldipeptide (MDP, i.v.) were used. Test and reference substances were applied at days - 3 and -1 before infection, except MDP, which was given once on day--before infection. CD4+ and CD8 + lymphocyte subpopulations were measured after infection as indicators of immunological treatment response. Groups of 20 mice each were infected by intranasal application of Sendai virus under anaesthesia. We found that the 1 x and 5 x human doses of Sinupret drops significantly prolonged the survival times (p < 0.05) compared to placebo. Additionally, ambroxol and MDP were comparably less effective. In all groups, changes in CD4 + and CD8 + T-lymphocyte subpopulations of the peripheral blood were observed, but no clear relationship to the treatment results was seen. It was concluded that Sinupret increases the resistance to an experimentally induced respiratory tract infection in mice. Moreover, the effect of Sinupret was superior to that of an immunostimulant (MDP) and of a synthetic secretagogue (ambroxolhydrochloride).

    Full Text Available Aqueous extracts of several plant species have shown promising in controlling root-knot nematode, Meloidogyne incognita (Kofoid & White, one of the most limiting agents for carrot cultivation. The current study evaluated the effect of aqueous extracts from seven botanical species applied to 40, 50, 60, 70 and 80 days after sowing 'Nantes' carrots in soil infested with root-knot nematode. Three other treatments included cassava wastewater, distilled water (control, which were applied in the same periods of the extracts application, in addition to carbofuran 50G (80Kg/ha, which was applied once at 60 days after carrot sowing. Evaluations were performed at 90 days after inoculation to determine shoot and root fresh weight, as well as the diameter and the length of principal roots and the number of galls on primary and secondary roots. Plants treated with cassava wastewater, extracts of Ricinus communis L. seeds, Crotalaria juncea L. seeds, R. communis leaves + branches + fruits, Chenopodium ambrosioides L. leaves + branches + inflorescences and Azadirachta indica A. Juss. seeds showed the highest rates of total weight (root + shoot and shoot weight. The extract of R. communis leaves + branches + fruits provides the highest total root weight and principal root diameter. Cassava wastewater and extracts of R. communis seeds provided the highest principal root weight. The extract of R. communis seeds and cassava wastewater can be considered promising for the alternative control of M. incognita.

    2008-11-01

    Mangosteen (Garcinia mangostana L., Clusiaceae) is a popular botanical dietary supplement in the United States, where it is used principally as an antioxidant. It is referred to as the "queen of fruits" in Thailand, a country of origin. The major secondary metabolites of mangosteen, the xanthones, exhibit a variety of biological activities including antibacterial, antifungal, antiinflammatory, antioxidant, antiplasmodial, cytotoxic, and potential cancer chemopreventive activities. Moreover, some of the xanthones from mangosteen have been found to influence specific enzyme activities, such as aromatase, HIV-1 protease, inhibitor κB kinase, quinone reductase, sphingomyelinase, topoisomerase and several protein kinases, and they also modulate histamine H(1) and 5-hydroxytryptamine(2A) receptor binding. Several synthetic procedures for active xanthones and their analogs have been conducted to obtain a better insight into structure-activity relationships for this compound class. This short review deals with progress made in the structural characterization of the chemical constituents of mangosteen, as well as the biological activity of pure constituents of this species and synthetic methods for the mangosteen xanthones.

    Full Text Available Salvia japonica Thunb. (Japan: Aki-no-Tamurasou was a perennial herb, protandry insect-pollinated, and self-incompatible with water-flow dispersed seed. We used allozyme loci to know genetic structure of a S. japonica population. We examined spatial autocorrelation of individuals within five distance class with Moran`s I statistics. The area of observation was in plot 5x5 m2 in Botanical Garden of Osaka City University, Kisaichi, Katano, Osaka Prefecture. The 8 loci examined were polymorphic, namely Aat-1, Aat-2, Pgi, Mnr, Pgm-1, Pgm-2, Idh, and 6-Pgd. Low levels of genetic diversity were found for 29 individuals. Ninety-two percent cases for all of distance class were similar and only 8% (8 of 105 cases were significant differences. This result indicated that the spatial genetic distributions in all of distance classes were all similar and no spatial autocorrelation of genotypes. Only in distance class 2 had one significantly positive cases (0.15 in Pgm-1c, indicating that spatial genetic structure in the study population was weak at most. In the other word that spatial pattern of the individuals within S. japonica population was random. Overall of the result was indicating that genotype among individuals of S. japonica changed distantly and tended to isolation in distance by seed dispersed.

    Full Text Available PG2 is a botanical drug that is mostly composed of Astragalus polysaccharides (APS. Its role in hematopoiesis and relieving cancer-related fatigue has recently been clinically investigated in cancer patients. However, systematic analyses of its functions are still limited. The aim of this study was to use microarray-based expression profiling to evaluate the quality and consistency of PG2 from three different product batches and to study biological mechanisms of PG2. An integrative molecular analysis approach has been designed to examine significant PG2-induced signatures in HL-60 leukemia cells. A quantitative analysis of gene expression signatures was conducted for PG2 by hierarchical clustering of correlation coefficients. The results showed that PG2 product batches were consistent and of high quality. These batches were also functionally equivalent to each other with regard to how they modulated the immune and hematopoietic systems. Within the PG2 signature, there were five genes associated with doxorubicin: IL-8, MDM4, BCL2, PRODH2, and BIRC5. Moreover, the combination of PG2 and doxorubicin had a synergistic effect on induced cell death in HL-60 cells. Together with the bioinformatics-based approach, gene expression profiling provided a quantitative measurement for the quality and consistency of herbal medicines and revealed new roles (e.g., immune modulation for PG2 in cancer treatment.

    The present plant life of the Rocky Flats site and surrounding area was documented. This documentation is intended as a base-line description which may be used by researchers and managers. The analysis of natural vegetation, including plant species inventory, vegetation composition study, and identification of major environmental control factors at the Rocky Flats site provides a data base on which future environmental decisions concerning, for example, future construction and handling of disturbance on this site can be made. The establishment of morphological norms for potential plant indicators of mutagenic hazards serves as a start for development of a vegetation-based system for detection of possible changes in plant life induced by accidental plutonium release around the plant. This study is not directed towards assessing any past or present industrial impacts of plutonium processing. The principal products from the contract are a list of vascular plants, bryophytes, and lichens, a 1:12,000 color vegetation map, five large scale (1:500) maps of special study and experimental areas, and a description of the morphological norms of two common vascular plant species.

    Seven wood samples from a petrified forest, in situ in ash flow deposits at Cheparain in the Tugen Hills (Kenya) in the Mpesida Beds, were discovered and studied. The age of the Mpesida Formation is estimated to be about 6.3 Ma on the basis of radio-isotope age determinations on the volcanic deposits, which overlie and underlie the sedimentary levels. The wood samples are mineralized with obvious sectors of differential mineralization, and different degrees of silica impregnation. All samples show heteroxylous structures corresponding to angiosperm dicotyledon trees. One sample consists in a half cylinder showing a well preserved mineralized structure of heteroxylous wood and probably corresponds to a fragment of root. This wood, with solitary (or in radial group) vessels, heterocellular multiseriate rays, paratracheal parenchyma in wide bands, and partly storied fusiform cells, clearly shows affinities with the genus Erythrina (Fabaceae). A slightly compressed branch, partly disturbed by injuries and highly mineralized shows solitary (or in short radial group) vessels, the rays uni-(bi) seriate are heterocellular, and the apotracheal parenchyma is in thin tangential bands. The closest affinities are with the genus Spirostachys (Euphorbiaceae). The other structures are poorly preserved (highly mineralized) and precise botanical affinities cannot be accessed. But the growth rings are distinct or diversely marked and the samples show semi-ring porous structures. They exhibit two different patterns. The growth rings reveal the presence of seasonal climate, and numerous injuries, a disturbance of the vegetation by animals and/or strong climatic events. Erythrina and Spirostachys are present in the extant vegetation of the Tana River Valley, in Kenya, which could represent a modern analogue for the vegetation of the Mpesida Beds prior to the major uplift of the Tugen Hills at the end of the Miocene.

    In fear of animal-associated diseases, there is a trend in searching for non-animal derived substitutes for existing excipients in the pharmaceutical industries. This paper aimed to screen cholesterol analogues as membrane stabilizers of liposomes from botanical sterols, including β-sitosterol, stigmasterol, ergosterol and lanosterol. Liposomes containing four kinds of sterols were prepared and evaluated in vitro and in vivo as oral delivery system of insulin. Liposomes containing β-sitosterol (Si-Lip), stigmasterol (St-Lip) and lanosterol (La-Lip) was found not to protect insulin against degradation. Only 10% of the initial insulin in liposomes was preserved after a 30 min exposure to simulated gastric fluids. However, the protective ability of liposomes containing ergosterol (Er-Lip) was similar to that of liposomes containing sodium glycocholate (Sgc-Lip) and superior to that of liposomes containing cholesterol (Ch-Lip). In addition, the blood glucose level can decrease to about 50% of initial level after oral Er-Lip which was significantly superior to the in vivo performance of Si-Lip and Ch-Lip and similar to Sgc-Lip. Er-Lips of ergosterol/phospholipids ratios of 1:4 or 1:6 exerts more pronounced protective ability of insulin in simulated gastrointestinal fluids and hypoglycemic effects in rats than other formulations. Furthermore, Er-Lips exerted low toxicity to Caco-2 cells through a cell viability study. Meahwhile, insulin permeability was significantly increased across Caco-2 monolayers by encapsulating in Er-Lip. It was concluded that ergosterol could be used as a substitute for cholesterol and bile salt derivatives in liposomes to enhance oral bioavailability of insulin.

    Carbon tetrachloride (CCl4)-induced hepatotoxicity is a common syndrome with simultaneous severe hepatocyte death and acute cholestasis. The purpose of the present study is to investigate the hepatoprotective effect of alisol B 23-acetate (AB23A), a natural triterpenoid from edible botanical Rhizoma alismatis, on acute hepatotoxicity induced by CCl4 in mice, and further to elucidate the involvement of farnesoid X receptor (FXR), signal transducers and activators of transcription 3 (STAT3) in the hepatoprotective effect. H&E staining, BrdU immunohistochemistry and TUNEL assay were used to identify the amelioration of histopathological changes, hepatocyte proliferation and apoptosis. Real-time PCR and western blot assay were used to elucidate the mechanisms underlying AB23A hepatoprotection. The results indicated that AB23A treatment in a dose-dependent manner resulted in protection against hepatotoxicity induced by CCl4via FXR activation. Through FXR activation, AB23A promoted hepatocyte proliferation via an induction in hepatic levels of FoxM1b, Cyclin D1 and Cyclin B1. AB23A also reduced hepatic bile acids through a decrease in hepatic uptake transporter Ntcp, bile acid synthetic enzymes Cyp7a1, Cyp8b1, and an increase in efflux transporter Bsep, Mrp2 expression. In addition, AB23A induced the expression of STAT3 phosphorylation, and STAT3 target genes Bcl-xl and SOCS3, resulting in decreased hepatocyte apoptosis. In conclusion, AB23A produces a protective effect against CCl4-induced hepatotoxicity, due to FXR and STAT3-mediated gene regulation. PMID:25747392

    This study was conducted to characterize the effects of feeding 3 plant extracts on gene expression in ileal mucosa of weaned pigs. Weaned pigs (n = 32, 6.3 ± 0.2 kg BW, and 21 d old) were housed in individual pens for 9 d and fed 4 different diets: a nursery basal diet as control diet, basal diet supplemented with 10 mg/kg of capsicum oleoresin, garlic botanical, or turmeric oleoresin. Results reported elsewhere showed that the plant extracts reduced diarrhea and increased growth rate of weaning pigs. Total RNA (4 pigs/treatment) was extracted from ileal mucosa of pigs at d 9. Double-stranded cDNA was amplified, labeled, and further hybridized to the microarray. Microarray data were analyzed in R using packages from the Bioconductor project. Differential gene expression was tested by fitting a mixed linear model equivalent to ANOVA using the limma package. Bioinformatics analysis was conducted by DAVID Bioinformatics Resources. Three pairwise comparisons were used to compare each plant extract diet with the control diet. Quantitative real time PCR was applied to verify the mRNA expression detected by microarray. Compared with the control diet, feeding capsicum oleoresin altered (P turmeric oleoresin altered (P turmeric oleoresin increased [Expression Analysis Systematic Explorer (EASE) < 0.05] the expression of genes related to integrity of membranes and tight junctions, indicating enhanced gut mucosa health, but decreased (EASE < 0.05) the cell cycle pathway. Feeding each of the 3 plant extracts enhanced (EASE < 0.05) the expression of genes associated with immune responses, indicating that feeding these plant extracts may stimulate the immune responses of pigs in the normal conditions. In conclusion, plant extracts regulated the expression of genes in ileal mucosa of pigs, perhaps providing benefits by enhancing the gut mucosa health and stimulating the immune system.

    Full Text Available The aim of this study was to characterize the anti-inflammatory mode of action of botanical extracts from rosehip (Rosa canina, willow bark (Salix alba, and nettle leaf (Urtica dioica in an in vitro model of primary canine articular chondrocytes. Methods. The biological effects of the botanical extracts were studied in chondrocytes treated with IL-1β for up to 72 h. Expression of collagen type II, cartilage-specific proteoglycan (CSPG, β1-integrin, SOX-9, COX-2, and MMP-9 and MMP-13 was examined by western blotting. Results. The botanical extracts suppressed IL-1β-induced NF-κB activation by inhibition of IκBα phosphorylation, IκBα degradation, p65 phosphorylation, and p65 nuclear translocation. These events correlated with downregulation of NF-κB targets including COX-2 and MMPs. The extracts also reversed the IL-1β-induced downregulation of collagen type II, CSPG, β1-integrin, and cartilage-specific transcription factor SOX-9 protein expression. In high-density cultures botanical extracts stimulated new cartilage formation even in the presence of IL-1β. Conclusions. Botanical extracts exerted anti-inflammatory and anabolic effects on chondrocytes. The observed reduction of IL-1β-induced NF-κB activation suggests that further studies are warranted to demonstrate the effectiveness of plant extracts in the treatment of OA and other conditions in which NF-κB plays pathophysiological roles.

    The aim of this work was to establish an analytical method for identifying the botanical origin of honey, as an alternative to conventional melissopalynological, organoleptic and instrumental methods (gas-chromatography coupled to mass spectrometry (GC-MS), high-performance liquid chromatography HPLC). The procedure is based on the {sup 1}H nuclear magnetic resonance (NMR) profile coupled, when necessary, with electrospray ionisation-mass spectrometry (ESI-MS) and two-dimensional NMR analyses of solid-phase extraction (SPE)-purified honey samples, followed by chemometric analyses. Extracts of 44 commercial Italian honeys from 20 different botanical sources were analyzed. Honeydew, chestnut and linden honeys showed constant, specific, well-resolved resonances, suitable for use as markers of origin. Honeydew honey contained the typical resonances of an aliphatic component, very likely deriving from the plant phloem sap or excreted into it by sap-sucking aphids. Chestnut honey contained the typical signals of kynurenic acid and some structurally related metabolite. In linden honey the {sup 1}H NMR profile gave strong signals attributable to the mono-terpene derivative cyclohexa-1,3-diene-1-carboxylic acid (CDCA) and to its 1-O-{beta}-gentiobiosyl ester (CDCA-GBE). These markers were not detectable in the other honeys, except for the less common nectar honey from rosa mosqueta. We compared and analyzed the data by multivariate techniques. Principal component analysis found different clusters of honeys based on the presence of these specific markers. The results, although obviously only preliminary, suggest that the {sup 1}H NMR profile (with HPLC-MS analysis when necessary) can be used as a reference framework for identifying the botanical origin of honey.

    Pine nuts are traditionally used in various part of the world for the preparation of desserts or sauces or in salads. Local production is not sufficient to cope with the high demand of pine nuts around the world, and countries such as China or Pakistan are exporting much of their production to Western countries. Almost all the nuts that are traditionally consumed belong to the Pinus genus, but over the past years, the number of consumer complaints following consumption of commercial pine nuts increased. Some consumers experienced taste disturbance lasting for up to two weeks after consumption. Food safety agencies raised some concerns regarding pine nuts imported from Asia and their association with taste disturbance. However, even though a formal association has not been found to date, the Pinus genus comprises species that are not classified as edible and could be eventually used to adulterate edible species. Pinus spp. seed lipids are known to contain very specific polyunsaturated fatty acids know as Delta5-olefinic acids. Seed fatty acid profile of conifers had been used in the past as a taxonomic marker, and in the present study to identify the botanical origin of pine nut in nine commercial products. Fast gas-liquid chromatography (GLC) was used to resolve the complete fatty acid profile of Pinus spp. samples in less than 5 min. A diagnostic index based on the relative levels of the main fatty acids including distinctive Delta5-olefinic acids was used to identify botanical origins. Results revealed the occurrence of the following Pinus spp. in commercial products: P. pinea, P. koraiensis, P. gerardiana, P. armandii and P. massoniana. The later two species, known as Chinese white pine and Chinese red pine, are only cultivated in China and are not listed as common source of edible pine nuts by the Food and Agriculture Organization (FAO). The present study shows that the botanical origin of pine nuts can be identified in products based on the fatty acid profile.

    植物学实验是一门对户外实践要求很强的课程,只有加强户外、野外实践,让学生多动手观察才能理论联系实际,消化课堂知识。过去实验课程设计过度关注植物的微观解剖结构,实验室通过显微镜观察装片的相关实验过多,导致学生户外实践能力较低。通过将三个实验室显微观察实验改为户外观察实验,如“生殖器官的观察”、“低等植物的观察”等,使户外实验比例大大增加,学生认识、观察、研究植物能力明显提高,达到了通过教改提高学生实践能力的初衷。同时也发现一些不足,如师资力量不足,实验课时少等,在今后需进一步改进。%The course of botanical experiment requires extracurricular practice,for only through close contact with nature and plant,and through observation,can students digest the knowledge. The past practice of instruction fo-cused too much on the observation of the structure of microscopic anatomy,which leads to the poor outdoor perform-ance of students. This reform changed 3 observational experiments in lab into outdoor ones,which raises the pro-portion of outdoor experiment. Meantime,students can develop their recognition and observation of plants,which meets the purpose of this reform. At last,some weaknesses remain to be improved like insufficient teaching staff, time shortage for experiment instruction.

    To analyse and predict recent and future climate change on a global scale exchange processes of greenhouse gases - primarily carbon dioxide - over various ecosystems are of rising interest. In order to upscale land-use dependent sources and sinks of CO2, knowledge of the local variability of carbon fluxes is needed. Among terrestrial ecosystems, urban areas play an important role because most of anthropogenic emissions of carbon dioxide originate from these areas. On the other hand, urban soils have the potential to store large amounts of soil organic carbon and, thus, contribute to mitigating increases in atmospheric CO2 concentrations. Research objectives: 1) estimate the seasonal dynamics of carbon dioxide production (emission - closed chamber technique and profile concentration - soil air sampling tubes method) by soils of Moscow State University Botanical Garden Arboretum planted with Picea obovata and Pinus sylvestris, 1) identification the factors that control CO2 production. The study was conducted with 1-2 weeks intervals between October 2013 and November 2015 at two sites. Carbon dioxide soil surface efflux during the year ranged from 0 to 800 mgCO2/(m2hr). Efflux values above 0 mgCO2/(m2hr) was observed during the all cold period except for only 3 weeks. Soil CO2 concentration ranged from 1600-3000 ppm in upper 10-cm layer to 10000-40000 ppm at a depth of 60 cm. The maximum concentrations of CO2 were recorded in late winter and late summer. We associate it with high biological activity (both heterotrophic and autotrophic) during the summer, and with physical gas jamming in the winter. The high value of annual CO2 production of the studied soils is caused by high organic matter content, slightly alkaline reaction, good structure and texture of urban soils. Differences in soil CO2 production by spruce and pine urban forest soils (in the pine forest 1.5-2.0 times higher) are caused by urban soil profiles construction, but not temperature regimes.

    Full Text Available High quality of bee pollen for commercial purpose is required. In order to attend the consumer with the best identification of the botanical and floral origin of the product, 25 bee pollen batches were investigated using two techniques of pollen grain preparation. The first started to identify pollen loads of different colors in two grams of each well mixed batch, and the second to identify pollen grains in a pool made of all the pollen loads comprised in two grams. The best result was obtained by this last technique, when a pollen grain suspension was dropped on a microscope slide and circa 500 pollen grains were counted per sample. This analysis resulted in the recognition of monofloral and bifloral pollen batches, while the use of the first technique resulted in all samples receiving a heterofloral diagnosis.É exigida alta qualidade para a comercialização de pólen apícola.

    Full Text Available The joint action of destruxins and three botanical insecticides, rotenone (Rot, azadirachtin (Aza and paeonolum (Pae against the cotton aphid, Aphis gossypii, was bioassayed. In laboratory experiment, several synergistic groups of destruxins with botanical insecticides were found by means of Sun’s Co-toxicity Coefficients (CTC and Finney’s Synergistic Coefficient (SC. The best synergistic effect was discovered in the ratio group Des/Rot 1/9 with the CTC or SC and LC50 values of 479.93 or 4.8 and 0.06 μg/mL, respectively. The second and third synergistic effects were recorded in the ratio groups Des/Rot 7/3 and 9/1. Although the ratio groups Des/Aza 6/4, Des/Pae 4/6, 3/7 and 2/8 indicated synergism by Sun’s CTC, they were determined as additive actions by Finney’s SC. Additive actions were also found in most of the ratio groups, but antagonism were recorded only in three ratio groups: Des/Pae 9/1, 7/3 and 6/4. In greenhouse tests, the highest mortality was 98.9% with the treatment Des/Rot 1/9 at 0.60 μg/mL, meanwhile, the treatments Des/Pae 4/6 and Des/Aza 6/4 had approximately 88% mortality.

    Alzheimer's disease (AD) is characterized by dysfunctional intracellular and extracellular biochemical processes that result in neuron death. This article summarizes hypotheses regarding cell dysfunction in AD and discusses the effectiveness of, and problems with, different therapies. Pharmaceutical therapies discussed include cholinesterase inhibitors, memantine, antihypertensive drugs, anti-inflammatory drugs, secretase inhibitors, insulin resistance drugs, etanercept, brain-derived neurotrophic factor, and immunization. Nutritional and botanical therapies included are huperzine A, polyphenols, Ginkgo, Panax ginseng, Withania somnifera, phosphatidylserine, alpha-lipoic acid, omega-3 fatty acids, acetyl L-carnitine, coenzyme Q10, various vitamins and minerals, and melatonin. Stimulatory therapies discussed are physical exercise, cognitive training, music, and socialization. Finally, treatment strategies are discussed in light of the benefits and drawbacks of different therapeutic approaches. It is concluded that potential risks of both approved and non-approved therapies should be weighed against the potential benefits and certain consequences of disease progression. Approaches that target several dysfunctions simultaneously and that emphasize nutritional, botanical, and stimulatory therapies may offer the most benefit at this time. PMID:21155625

    Full Text Available Botanical insecticides have long been touted as attractive alternatives to synthetic chemical insecticides for pest management because botanicals reputedly pose little threat to the environment or to human health. The body of scientific literature documenting bioactivity of plant derivatives to arthropods pests continues to expand i.e. repellents based on essential oils extracted from Chenopodium ambrosioides, Eucalyptus saligna, Rosmarinus officinalis to mosquitoes, or cinnamon oil, sandalwood oil and turmeric oil are previously reported as insect repellents evaluatede in the laboratory conditions. With the constantly increasing problems of insecticide resistance and increasing public concerns regarding pesticide safety, new, safer active ingredients are becoming necessary to replace existing compounds on the market. The present study carried out in the period 2010-2012 comprises a review of two insect repellents, followed by some new research conducted in our laboratory on plant-derived insect repellents. The two alkaloids tested against the Colorado potato beetle, Leptinotarsa decemlineata Say in laboratory conditions was obtained by water and alchohol extraction from two vegetal species, Cichorium intybus L. (Asterales:Asteraceae and Delphinium consolida L. (Ranales:Ranunculaceae. The tests carried out in laboratory and field experimentally plots under cages permit to evaluate several other compounds for repellent activity of lacctucin alkaloids.

    1979-12-01

    Full Text Available Five papers cover different aspects of the contributions to and role of botany in the development of the Republic of South Africa. Two papers sum up the contributions for the non-agricultural and agricultural sectors. The introductory paper by D. J. B. Killick provides a short historical account of the Botanical Research Institute, followed by a discussion of the contributions of the Institute to botany in South Africa through its National Herbarium and identification service as well as researches in taxonomy, plant anatomy, cyto-genetics, ecology, economic botany and data processing. B. de Winter emphasizes the fundamental role of taxonomy and bio-systematics for planning and the optimal use of the natural plant resources. The current support for taxonomy and biosystematics is examined and proposals made for improving progress in the Flora of Southern Africa series. For plant physiology, N. Grobbelaar discusses, firstly, the ways whereby the productivity of a plant species with its characteristic genetic constitution can be raised by determining and modifying for optimal response the effects of environmental factors such as spacing, mineral nutrition, water provision, etc.; and, secondly, usually when the first means has been achieved, of improving plant productivity by altering the genetic constitution of the plant so that it can perform better than its ancestors under the prevailing conditions. After discussing and illustrating the applications and roles of plant ecology, D. Edwards concludes that basic plant ecological research is required, firstly, at the regional level through regional plant ecological studies to supply the essential local knowledge needed by researchers, planners and users of the land; and, secondly, at the more detailed level where knowledge is needed of the processes and factors that govern the behaviour of vegetation so that it can be properly used, managed and manipulated.

    Full Text Available Alzheimer′s disease (AD is a progressive neurodegenerative disease, wherein a progressive loss of cholinergic synapses occurs in hippocampus and neocortex. Decreased concentration of the neurotransmitter, acetylcholine (ACh, appears to be critical element in the development of dementia, and the most appropriate therapeutic approach to treat AD and other form of dementia is to restore acetylcholine levels by inhibiting both major form of cholinesterase: Acetylcholinesterase (AChE and butyrylcholinesterase (BChE. Consequently, researches have focused their attention towards finding cholinesterase inhibitors from natural products. A large number of such inhibitors have been isolated from medicinal plants. This review presents a comprehensive account of the advances in field of cholinesterase inhibitor phytoconstituents. The structures of some important phytoconstituents (collected through www.Chemspider.com are also presented and the scope for future research is discussed.

    The estimation of medium-term sheet erosion rates represents still a challenge in areas with long land use history. In the present paper, a new methodology for estimating medium-term sheet erosion rates is presented and applied in a wooded rangeland (dehesa). This human-induced semi-natural ecosystem is widespread in SW Iberian Peninsula and is characterized by centuries of agrosilvopastoral land use, being livestock breeding the most important economic activity at present. Vast areas are covered by shallow and poor soils, pointing to a long history of soil erosion. Research carried out in a representative area with open plots revealed low soil loss rates and degradation studies showed high spatial variation related with land use intensity. Knowledge on past soil erosion rates and its relation with land use is necessary in order to understand present soil properties and also for giving adequate advice on land management. The present paper presents results of a pilot study on historical soil erosion in Mediterranean wooded rangelands. The methodology is based on the analysis of the morphology of tree stems, exposed roots and surface micro-topography using data obtained with a Terrestrial Laser Scanner. Specifically, botanical evidences were used to estimate the antecedent level of the soil surface. Afterwards, previous and current surfaces were confronted in order to obtain a volume of soil loss in the area influenced by the tree canopy, as well as for the open spaces. On the other hand, the age of the trees in the study area was estimated by means of an existing tree growth model. Finally, soil erosion rates were calculated using the volume of soil loss and the estimated age of every tree. The sampling was carried out in a farm in the Spanish province of Cáceres, with a two-layered vegetation, of grasses and scattered trees (Quercus ilex). Climate is Mediterranean with mean annual temperature of 160C and an annual rainfall of 620 mm. Soils are very shallow

    Opuntia ficus-indica f. inermis (cactus pear) flowers have wide application in folk medicine. However, there are few reports focusing on their biological activity and were no reports on their chemical composition. The nutrient composition and hexane extracts of Opuntia flowers at 4 flowering stages and their antibacterial and antifungal activities were investigated. The chemical composition showed considerable amounts of fiber, protein, and minerals. Potassium (K) was the predominant mineral followed by calcium (Ca), magnesium (Mg), sodium (Na), iron (Fe), and zinc (Zn). The main compounds in the various hexane extracts were 9.12-octadecadienoic acid (29-44%) and hexadecanoic acid (8.6-32%). The antibacterial activity tests showed that O. inermis hexane extracts have high effectiveness against Escherichia coli and Staphylococcus aureus, making this botanical source a potential contender as a food preservative or food control additive.

    China's rich floral diversity includes more than 33 000 vascular plant species, representing approximately 10 percent of all known plant species. Over half of these species are endemic to China. However, China's rapid economic development in the last 30 years and continuous population growth have seriously damaged plant resources in the wild and the ecological environment, resulting in a dramatic increase in the number of endangered species. There are nearly 4 000 to 5 000 higher plants that are now threatened or on the verge of extinction. To help halt the loss of Chinese plant diversity, Botanic Gardens Conservation International (BGCI) has developed a China programme and opened its first office based in Guangzhou in 2008. This office works along with Chinese partners aiming to secure Chinese plant diversity through integrated conservation approaches with reintroduction/population reinforcement, engagement of local communities in conservation activities, capacity building in horticulture and environmen tal education and public outreach.

    The impact of viaduct construction on the vegetation of a river valley was studied in Central Poland (Natura 2000 site PLH100006). The research aimed at assessing the suitability of ALS (airborne laser scanning), soil, and botanical data for monitoring the environmental effects of right-of-way reclamation 1 year after the road construction. Based on the data mentioned above, the following problems were identified: changes in topography and hydrological conditions of the valley as a result of improper land levelling, the use of inadequate soil for reclamation, no spontaneous regeneration of natural vegetation along the entire right-of-way, as well as the abundant occurrence of invasive species. The results of analysis were used to define strategies for mitigation of adverse impacts of the viaduct construction. PMID:26527333

    Full Text Available The Subsection for Sightless People belongs to the Ornamental Section and started in the autumn of 1991. In 2008 we tried to reorganize this subsection, first of all by enriching the collection of species exposed to the visitors, introducing a new model of labels and using especial props for the plants. Many species from Lamiaceae family have been chosen, characterized by a high level of essential oils, volatile phenolic compounds, alkaloids, balsams, tannins, liberating strong-scented odors, which facilitate their recognition by the sightless persons. At the same time, a lot of Asteraceae species are displayed, while in the autumn the sightless people enjoy the numerous chrysanthemum varieties from the Botanic Garden’s collection. All of the specimens bear labels with information in Latin and Braille System.

    The microbiological characterization of the brown forest soils in the territory of the Botanical Garden-Institute of the Far East Division of the Russian Academy of Sciences in southern Primor’e is given. The high humus content and weakly acid reaction of these soils were shown to provide the optimal conditions for the development of bacteria. In the brown forest soils differing in the thickness of the humus horizons, all the ecologic-trophic groups of bacteria were present and the bacterial communities were highly diverse. The structure of the bacterial communities was identical in all the organomineral horizons of the soils and varied greatly by the seasons. In the anthropogenically disturbed soils, the share of corynebacteria, which are resistant to stress and capable of the destruction of xenobiotics, decreased.

    Mycotoxins are toxic secondary metabolites produced by certain molds and are common contaminants of many important food crops, such as grains, nuts, and spices. Some mycotoxins are found in fruits, vegetables, and botanical roots. These contaminants have a broad range of toxic effects, including carcinogenicity, immunotoxicity, neurotoxicity, and reproductive and developmental toxicity. The public health concerns related to both acute and chronic effects of mycotoxins in animals have prompted more than 100 countries to establish regulatory limits for some of the well-known mycotoxins, such as the aflatoxins (AFL). Our research focused on method development for 2 of these toxins, AFL and ochratoxin A (OTA), in ginseng and other selected botanical roots. Methods using an immunoaffinity column (IAC) cleanup, liquid chromatographic separation, and fluorescence detection were modified and evaluated. Two types of IAC cleanup were evaluated: IAC for AFL, and IAC for both AFL and OTA. Three derivatization techniques to enhance the fluorescence of the AFL were compared: precolumn trifluoroacetic acid, postcolumn bromination, and postcolumn ultraviolet irradiation. No derivatization was needed for OTA. Results for AFL using the single analyte IAC cleanup and the 3 derivatization techniques were all comparable for ginseng and for other roots such as ginger, licorice, and kava-kava. Recoveries of added AFL for ginseng at levels from 2 to 16 ng/g were about 80%. Using IAC cleanup for both AFL and OTA recoveries of added AFL for ginseng at 4-16 ng/g were about 70%, and for ginger, licorice, and kava-kava were about 60%. Recoveries of added OTA for ginseng, ginger, and echinacea at 4 ng/g were about 55%. PMID:16792061

    Full Text Available Abstract Background Botanical products are frequently used for treatment of nasal allergy. Three of these substances, Cinnamomum zeylanicum, Malpighia glabra, and Bidens pilosa, have been shown to have a number of anti-allergic properties in-vitro. The current study was conducted to determine the effects of these combined ingredients upon the nasal response to allergen challenge in patients with seasonal allergic rhinitis. Methods Twenty subjects were randomized to receive the combination botanical product, (CBP 2 tablets three times a day, loratadine, 10 mg once a day in the morning, or placebo, using a randomized, double-blinded crossover design. Following 2 days of each treatment and during the third day of treatment, subjects underwent a nasal allergen challenge (NAC, in which nasal symptoms were assessed after each challenge dose and every 2 hours for 8 hours. Nasal lavage fluid was assessed for tryptase, prostaglandin D2, and leukotriene E4 concentrations and inflammatory cells. Results Loratadine significantly reduced the total nasal symptom score during the NAC compared with placebo (P = 0.04 while the CBP did not. During the 8 hour period following NAC, loratadine and the CBP both reduced NSS compared with placebo (P = 0.034 and P = 0.029, respectively. Analysis of nasal lavage fluid demonstrated that the CBP prevented the increase in prostaglandin D2 release following NAC, while neither loratadine nor placebo had this effect. None of the treatments significantly affected tryptase or leukotriene E4 release or inflammatory cell infiltration. Conclusion The CBP significantly reduced NSS during the 8 hours following NAC and marginally inhibited the release of prostaglandin D2 into nasal lavage fluid, suggesting potential clinical utility in patients with allergic rhinitis.

    Traditional Chinese medicines (TCMs)-based products are becoming more and more popular over the world. To ensure the safety and efficacy, authentication of Chinese medicinal materials has been an important issue, especially for that with multiple botanical origins (one-to-multiple). Taking Clematidis Radix et Rhizoma (CRR) as a case study, we herein developed an integrated platform based on metabolite profiling and chemometrics analysis to characterize, classify, and predict the "one-to-multiple" herbs. Firstly, the predominant constituents, triterpenoid saponins, in three Clematis CRR were rapid characterized by a novel UPLC-QTOF/MS-based strategy, and a total of 49 triterpenoid saponins were identified. Secondly, metabolite profiling was performed by UPLC-QTOF/MS, and 4623 variables were extracted and aligned as dataset. Thirdly, by using pattern recognition analysis, a clear separation of the three Clematis CRR was achieved as well as a total number of 28 variables were screened as the valuable variables for discrimination. By matching with identified saponins, these 28 variables were corresponding to 10 saponins which were identified as marker compounds. Fourthly, based on the relative intensity of the marker compounds-related variables, genetic algorithm optimized support vector machines (GA-SVM) was employed to predict the species of CRR samples. The obtained model showed excellent prediction performance with a prediction accuracy of 100%. Finally, a heatmap visualization was employed for clarifying the distribution of identified saponins, which could be useful for phytochemotaxonomy study of Clematis herbs. These results indicated that our proposed platform was a powerful tool for chemical profiling and discrimination of herbs with multiple botanical origins, providing promising perspectives in tracking the formulation processes of TCMs products.

    The biggest hurdle in the treatment of acne vulgaris is patient non-compliance that is due in large part to poor tolerability to common acne medications. As such, new acne treatments must be developed that balance good anti-acne efficacy with excellent tolerability in order to ensure patient adherence and by extension ensure good clinical outcomes. The goal of the present study was to determine the tolerability and efficacy of a novel skin care system, composed of a cleanser, containing 1% salicylic acid and botanical ingredients, and a treatment gel, containing 1% salicylic acid, 10% buffered glycolic acid and botanical ingredients for the treatment of mild acne. In this single-center, open-label clinical study, 25 male and female volunteers used the test cleanser and test gel twice daily over six weeks. Tolerability assessments showed that the skin care regimen was very well tolerated by all study volunteers. Acne severity was significantly reduced by two acne grades at six weeks. Inflammatory lesion counts were significantly reduced, on average, by 59.06% (P ≤ 0.0001), 91.62% (P ≤ 0.0001), 90.85% (P ≤ 0.0001) and by 98.55% (P ≤ 0.0001) at weeks 1, 2, 4, and 6, respectively. Non-inflammatory lesion counts were reduced, on average, by 13.54% (ns), 38.95% (P ≤ 0.0001), 44.48% (P ≤ 0.0001), and by 56.10% (P ≤ 0.0001) at weeks 1, 2, 4, and 6, respectively. Standardized photography also demonstrated a progressive reduction in acne lesions over time. In conclusion, results of the present study suggest that the tested skin care regimen offers rapid acne clearance and excellent tolerability that together may help to improve patient adherence as well as treatment outcome.

    A method for providing chemical energy and energetic compositions of matter consisting of thin layers of substances which will exothermically react with one another. The layers of reactive substances are separated by thin layers of a buffer material which prevents the reactions from taking place until the desired time. The reactions are triggered by an external agent, such as mechanical stress or an electric spark. The compositions are known as metastable interstitial composites (MICs). This class of compositions includes materials which have not previously been capable of use as energetic materials. The speed and products of the reactions can be varied to suit the application.

    We investigate a possibility of a composite Z' vector boson. For the compositeness, the required gauge coupling g in low energy is not so big, g^2/(4\\pi) > 0.015 in the case of the U(1)_{B-L} model. We show that the Stueckelberg model is effectively induced in low energy via the fermion loop from the Nambu-Jona-Lasinio (NJL) model having the vectorial four-fermion interaction. In terms of the renormalization group equations (RGE's), this situation is expressed by the compositeness conditions. We find that the solutions of the RGE's with the compositeness conditions are determined by the infrared fixed points. As a result, the ratio of the masses of the extra electroweak singlet scalar and the right-handed neutrino is fixed. The mass of the composite Z' boson contains the contribution \\Delta of the Stueckelberg mass term. This nonzero \\Delta might be a remnant of a strongly interacting theory in high energy.

    European Regulation 1169/2011 requires producers of foods that contain refined vegetable oils to label the oil types. A novel rapid and staged methodology has been developed for the first time to identify common oil species in oil blends. The qualitative method consists of a combination of a Fourier Transform Infrared (FTIR) spectroscopy to profile the oils and fatty acid chromatographic analysis to confirm the composition of the oils when required. Calibration models and specific classification criteria were developed and all data were fused into a simple decision-making system. The single lab validation of the method demonstrated the very good performance (96% correct classification, 100% specificity, 4% false positive rate). Only a small fraction of the samples needed to be confirmed with the majority of oils identified rapidly using only the spectroscopic procedure. The results demonstrate the huge potential of the methodology for a wide range of oil authenticity work. PMID:26190602

    The selection of an appropriate calibration set is a critical step in multivariate method development. In this work, the effect of using different calibration sets, based on a previous classification of unknown samples, on the partial least squares (PLS) regression model performance has been discussed. As an example, attenuated total reflection (ATR) mid-infrared spectra of deep-fried vegetable oil samples from three botanical origins (olive, sunflower, and corn oil), with increasing polymerized triacylglyceride (PTG) content induced by a deep-frying process were employed. The use of a one-class-classifier partial least squares-discriminant analysis (PLS-DA) and a rooted binary directed acyclic graph tree provided accurate oil classification. Oil samples fried without foodstuff could be classified correctly, independent of their PTG content. However, class separation of oil samples fried with foodstuff, was less evident. The combined use of double-cross model validation with permutation testing was used to validate the obtained PLS-DA classification models, confirming the results. To discuss the usefulness of the selection of an appropriate PLS calibration set, the PTG content was determined by calculating a PLS model based on the previously selected classes. In comparison to a PLS model calculated using a pooled calibration set containing samples from all classes, the root mean square error of prediction could be improved significantly using PLS models based on the selected calibration sets using PLS-DA, ranging between 1.06 and 2.91% (w/w).

    Female pattern hair loss (FPHL), also known as female androgenic alopecia, affects over 21 million women in the United States with devastating effects on self-esteem and psychosocial functioning. Topical minoxidil 2% and 5% formulations are the only US Food and Drug Administration-approved treatments for FPHL. The length of time it typically takes to observe the benefits is a challenge for many patients, and may affect adherence to treatment. Herbal extracts, which are also believed to promote healthier-looking hair, have a long history of use in hair care formulations. The safety and efficacy of a twice-daily regimen of 2% minoxidil solution used in combination with the botanical hair solution for 12 weeks in 54 subjects was evaluated in a multicenter, single-arm, open-label study. Assessments included investigator and subject ratings of improvement and subject satisfaction. Investigator ratings indicated significant improvement in hair growth and overall treatment benefits in as early as 6 weeks (Pminoxidil treatment adherence. PMID:27050694

    We recently defined cancer metastatic chemoprevention as utilizing safe and effective molecules to comprehensively prevent the spark of activation-adhesion-extravasation-proliferation metastatic cascade caused by circulating tumor cells (CTCs). The strategy focuses on preventing the most important starting point of the cascade. We identified an extract from a well-known medical plant Murraya paniculata, which inhibited both embryonic implantation to human endometrium as traditionally-used for abortion and CTC adhesion to human endothelium. Here, we separated and characterized five coumarin-containing components (Z1-Z5) from the botanic extract. Flow cytometry revealed that within 1-100 μg/mL, Z3 and Z5 down-regulated EpCAM expression in human colon HCT116, whereas, Z1 and Z2 did oppositely. Warfarin and Z1-Z5 component mixture (CM) also down-regulated EpCAM expression. The down-regulation of EpCAM by Z3, Z5, CM and warfarin was confirmed by western blotting, and caused inhibition on adhesion of cancer cells to human endothelial cells. Rat coagulation study showed that warfarin prolonged prothrombin time, whereas, Z3 did not. The present studies revealed that, for the first time, warfarin and coumarin-like components Z3, Z5 and CM from Murraya paniculata could directly inhibit EpCAM-mediated cell-cell adhesion.

    Atomistic metaphysics motivated an explanatory strategy which science has pursued with great success since the scientific revolution. By decomposing matter into its atomic and subatomic parts physics gave us powerful explanations and accurate predictions as well as providing a unifying framework for the rest of science. The success of the decompositional strategy has encouraged a widespread conviction that the physical world forms a compositional hierarchy that physics and other sciences are progressively articulating. But this conviction does not stand up to a closer examination of how physics has treated composition, as a variety of case studies will show.

    Botanical gardens (BGs) have attracted millions of visitors worldwide; therefore, BGs have become important sites for displaying and education for biodiversity. Understanding garden visitors' motivations and their traveling satisfactory degree is crucial for BG management and its role in public education. In this study, we conducted survey in five Chinese BGs, I.e., Xiamen BG, Wuhan BG of Chinese Academy of Sciences (CAS), Beijing BG, Kunming BG of CAS and Xishuangbanna Tropical Botanical Garden of CAS. We aimed to understand visitors' traveling motivation and the degree of satisfaction after they visited the gardens by questionnaire survey. The main results are as follows: (1) The motivations for visitors differed among the five BGs. "To get close to nature" was the most common motivation, followed by "To get relax" and "To enjoy the beautiful scenery". In Xiamen BG, "To be together with friends or relatives" was also one of the motivations. (2) "To gain relative knowledge" as the motivation did not get significant support. (3) The visitors were satisfied by the visit to the five BGs. The authors also discussed how BGs could adjust their management in order to fit visitors' motivation meanwhile play a better role in scientific and environmental education.%植物园每年都吸引大量的游客,是向公众展示生物多样性和开展生物多样性教育的重要场所.了解游客参观植物园的动机以及游览后的满意度,对植物园的运营及科普功能的发挥至关重要.作者选择厦门园林植物园、中国科学院武汉植物园、北京市植物园、中国科学院昆明植物研究所植物园和中国科学院西双版纳热带植物园5个植物园为研究对象,通过向游览后即将离园的游客发放问卷,调查游客的游览动机和满意度,分析了其社会学因素,得到了以下研究结果:(1)不同植物园的游客参观植物园的动机不尽相同.“亲近自然”是游客游览植物园的普遍动机,

    1973-01-01

    The earth's atmosphere is made up of a number of gases in different relative amounts. Near sea level and up to about 90 km, the amount of these atmospheric gases in clean, relatively dry air is practically constant. Four of these gases, nitrogen, oxygen, argon, and carbon dioxide, make up 99.99 percent by volume of the atmosphere. Two gases, ozone and water vapor, change in relative amounts, but the total amount of these two is very small compared to the amount of the other gases. The atmospheric composition shown in a table can be considered valid up to 90 km geometric altitude. Above 90 km, mainly because of molecular dissociation and diffusive separation, the composition changes.

    Botanical insecticides may provide alternatives to synthetic insecticides for controlling Spodoptera litura (F.) and they are target specific, biodegradable, and harmless to mammals. Eight natural chemical compounds with larvicidal activity were identified from fraction F6 of C. guianensis flower extract. Probit analysis of 95% confidence level exposed an LC50 of 223ppm against S. litura third instar larvae. The growth and development of S. litura was affected in sub-lethal concentrations of fraction F6 (50, 100, 150 and 200ppm) compared to controls. Similarly nutritional indices values decreased significantly compared to controls. Fraction F6 also damaged the gut epithelial layer and brush border membrane (BBM). This study also resolved the effects of toxicity to non-target earthworm treated with fraction F6 and chemical pesticides (monotrophos and cypermethrin) and the results showed that fraction F6 had no harmful effect on E. fetida. Further, fraction F6 was eluted and sub fractions F6c (50ppm) showed high mortality against S. litura third instar larvae. Octacosane from fraction F6c was established and confirmed using IR spectrum and HPLC. The time of retention of fraction F6c was confirmed with the octacosane standard. Fraction F6 of C. guianensis extract caused dose-dependent mortality towards S. litura. Octacosane in fraction F6c was establish to be the prominent chemical compound associated with causing mortality but other compounds present in the fraction F6 were shown to be associated with changes in development of S. litura at low dosages. S. litura at low dosage. Therefore, these findings suggest that octacosane may be one of the major insecticidal compounds affecting S. litura survival.

    Full Text Available Abstract Background It remains unclear whether estrogenic botanical supplement (EBS use influences breast cancer survivors' health-related outcomes. Methods We examined the associations of EBS use with health-related quality of life (HRQOL, with fatigue, and with 15 hormone-related symptoms such as hot flashes and night sweats among 767 breast cancer survivors participating in the Health, Eating, Activity, and Lifestyle (HEAL Study. HRQOL was measured by the Medical Outcomes Study short form-36 physical and mental component scale summary score. Fatigue was measured by the Revised-Piper Fatigue Scale score. Results Neither overall EBS use nor the number of EBS types used was associated with HRQOL, fatigue, or hormone-related symptoms. However, comparisons of those using each specific type of EBS with non-EBS users revealed the following associations. Soy supplements users were more likely to have a better physical health summary score (odds ratio [OR] = 1.66, 95% confidence interval [CI] = 1.02-2.70. Flaxseed oil users were more likely to have a better mental health summary score (OR = 1.76, 95% CI = 1.05-2.94. Ginseng users were more likely to report severe fatigue and several hormone-related symptoms (all ORs ≥ 1.7 and all 95% CIs exclude 1. Red clover users were less likely to report weight gain, night sweats, and difficulty concentrating (all OR approximately 0.4 and all 95% CIs exclude 1. Alfalfa users were less likely to experience sleep interruption (OR = 0.28, 95% CI = 0.12-0.68. Dehydroepiandrosterone users were less likely to have hot flashes (OR = 0.33, 95% CI = 0.14-0.82. Conclusions Our findings indicate that several specific types of EBS might have important influences on a woman's various aspects of quality of life, but further verification is necessary.

    We present an overview of composite Higgs models in light of the discovery of the Higgs boson. The small value of the physical Higgs mass suggests that the Higgs quartic is likely loop generated, thus models with tree-level quartics will generically be more tuned. We classify the various models (including bona fide composite Higgs, little Higgs, holographic composite Higgs, twin Higgs and dilatonic Higgs) based on their predictions for the Higgs potential, review the basic ingredients of each of them, and quantify the amount of tuning needed, which is not negligible in any model. We explain the main ideas for generating flavor structure and the main mechanisms for protecting against large flavor violating effects, and present a summary of the various coset models that can result in realistic pseudo-Goldstone Higgses. We review the current experimental status of such models by discussing the electroweak precision, flavor and direct search bounds, and comment on UV completions and on ways to incorporate dark ma...

    The estrogen receptors (ERs) ERα and ERβ mediate the actions of endogenous estrogens as well as those of botanical estrogens (BEs) present in plants. BEs are ingested in the diet and also widely consumed by postmenopausal women as dietary supplements, often as a substitute for the loss of endogenous estrogens at menopause. However, their activities and efficacies, and similarities and differences in gene expression programs with respect to endogenous estrogens such as estradiol (E2) are not fully understood. Because gene expression patterns underlie and control the broad physiological effects of estrogens, we have investigated and compared the gene networks that are regulated by different BEs and by E2. Our aim was to determine if the soy and licorice BEs control similar or different gene expression programs and to compare their gene regulations with that of E2. Gene expression was examined by RNA-Seq in human breast cancer (MCF7) cells treated with control vehicle, BE or E2. These cells contained three different complements of ERs, ERα only, ERα+ERβ, or ERβ only, reflecting the different ratios of these two receptors in different human breast cancers and in different estrogen target cells. Using principal component, hierarchical clustering, and gene ontology and interactome analyses, we found that BEs regulated many of the same genes as did E2. The genes regulated by each BE, however, were somewhat different from one another, with some genes being regulated uniquely by each compound. The overlap with E2 in regulated genes was greatest for the soy isoflavones genistein and S-equol, while the greatest difference from E2 in gene expression pattern was observed for the licorice root BE liquiritigenin. The gene expression pattern of each ligand depended greatly on the cell background of ERs present. Despite similarities in gene expression pattern with E2, the BEs were generally less stimulatory of genes promoting proliferation and were more pro-apoptotic in their

    The present study is carried out to evaluate the toxic efficiency and delayed effects of five botanical oils on the greasy cut worm Agrotis ipsilon (Lepidoptera: Noctuidae), as a trial for the attainment of a possible use of an alternative safe and effective phytochemicals against the insect-pest. So as to minimize or prevent the repeated usage of conventional insecticides, then reduce the environmental pollution as well as the occurring hazards to man and domestic animal due to the use of the pesticides alone. Four tested concentrations (0.5, 1.0, 1.5 and 2.5% v/v) from each of camphor, red basil, menthol, rose and anise oils, were bioassayed by treating the offered castor oil bean leaves, to the 4th instar larvae along 48h, under the laboratory higrothermic conditions of 25±2 °C and 65±5% R.H. The obtained results showed that the five tested oils were found to have more or less toxic activity and drastic effects on the inspected parameters of fitness components of the treated parent generation of the insect, in particular, pupae, emerged adult moths and laid eggs/female. In this respect camphor and red basil oils were highly effective, followed by menthol oil, anise oil and the least effective one was rose oil. Moreover, the assessed unprofitable delayed effects on the going on of the biological performance within the treated insects showed the adverse effects on the fitness components of the consequent generations (fs) post (p) one treatment with each of the bioassyed oils. The prevalence of adverse effects and disturbance in the going on biological performance through the period of (p) generation; which is followed by the distinct failure of insect development in (f1) generation were recorded for each of the tested menthol oil at 0.5 and 1.5% (v/v); camphor oil at 1.5 and 2.5% and red basil oil at 2.5% (v/v). While anise and rose oils were somewhat less efficient causing the distinct failure of the following generations up to the 3rd and/or the 6th ones

    Trametes versicolor is a mushroom used as a traditional Chinese medicine (Yun-zhi) for a wide array of seemingly disparate conditions. We hypothesized that many of its multiple purported activities could be mediated through stimulation of beneficial mutualist components of the microbiota. Human fecal microbiota was cultured anaerobically to determine its ability to ferment a common extract of T. versicolor, designated polysaccharide peptide (PSP), and the ability of PSP to alter the composition of the microbial community. The presence of PSP and fructooligosaccharides (FOS, a common prebiotic) in the medium, but not cellulose, significantly increased levels of Bifidobacterium spp. PSP also elevated Lactobacillus spp., while reducing Clostridium spp., Staphylococcus spp. and Enterococcus spp. Levels of Streptococcus spp., Bacteroides spp. and Escherichia did not significantly change. Fermentation of PSP increased the concentration of organic acids (lactate and short-chain fatty acids), decreased the pH, and induced β-galactosidase and β-glucosidase activities. The genera of the human microbiota that are promoted by FOS and other prebiotics are also stimulated by the Trametes versicolor extract, PSP. Thus, Trametes versicolor, a common East Asian botanical, contains putative prebiotic agents that alter human gut microbiota and pH. This prebiotic-like activity may help explain some of the plethora of the health benefits attributed to this traditional Chinese medicine. PMID:23435630
