    Full Text Available Chlorotic spots have been observed in plants of Clerodendrum x speciosum growing in residential gardens and parks in Piracicaba, SP, Brazil. Thin sections of diseased tissues revealed characteristic cytopathic effects of the nuclear type of the Brevipalpus (Acari: Tenuipalpidae mite-transmitted viruses (BTrV. Brevipalpus mites, identified as B. phoenicis, infesting symptomatic C. x speciosum plants transmitted the pathogen to healthy C. x speciosum and to C. thomsonae, Gomphrena globosa, Hibiscus cannabinus, H. coccineus, H. schizopetalus, Salvia leucantha, Spathiphyllum wallasi and Tetragonia expansa causing chlorotic spots on their leaves. Mechanical inoculation using leaf extracts from infected C. x speciosum resulted in chlorotic spots on inoculated C. x speciosum, Chenopodium quinoa, C. amaranticolor, G. globosa, H. cannabinus, H. coccineus and T. expansa leaves. C. amaranticolor and C. quinoa kept at 28 - 30°C became systemically infected. The same cytopathic effects caused by the nuclear type of BTrV were seen in tissues from all infected test plants by electron microscopy. The virus was purified from systemically infected leaves of C. amaranticolor and C. quinoa. A polyclonal antiserum obtained from an immunized rabbit presented a strong reaction with the homologous antigen in ELISA tests. The results suggest that this chlorotic spot disease of C. x speciosum is caused by a new species of the nuclear type of BTrV, tentatively named Clerodendrum chlorotic spot virus (ClCSV.Manchas cloróticas e necróticas foram observadas em folhas de várias plantas de coração-sangrento (Clerodendrum x speciosum cultivadas em parques e jardins em Piracicaba, SP, associadas à infestação pelo ácaro tenuipalpídeo Brevipalpus phoenicis.

    Full Text Available Roots of Clerodendrum phlomidis are used by the local people of Dibrugarh district of Assam state India as a dietary supplement for treating weight issues and are also mentioned in the traditional system of Indian medicine as a remedy for obesity. We examined the anti-obesity effect of Clerodendrum phlomidis (family Verbenaceae L. roots against cafeteria diet (CD and progesterone-induced obesity. In CD-induced model obesity was induced by feeding CD for 48-days and increase in body weight and fat storage was suppressed co-administration with methanolic extract of Clerodendrum phlomidis (MECP at 400 mg/kg. Blood analysis showed that the levels of triglyceride and cholesterol were significantly lowered by MECP administration and there is subsequent rise in HDL-cholesterol level. From this experiment, we demonstrated that MECP is effective in ameliorating the CD-induced hyperglycemia, hyperinsulimenia, dyslepidemia, increase in wet weight of white adipose tissue, and hypertrophy of fat cells. In drug induced obesity model hyperphagia was induced by progesterone (10 mg/kg s.c. for 28 days and was suppressed by co-administration with MECP in dose dependent manner. It is tempting to speculate that these protective effects shown by Clerodendrum phlomidis is by multiple mechanisms. MECP contains β-sitosterol in the abundant quantity because of the structural similarity it do the physical competition with natural sterols while absorption of food stuffs from GIT and moreover the crude saponin and flavonoid has been reported for it′s the appιtit suppressant property and hence reduces hyperphagia produced by progesterone. This is the first report demonstrating that Clerodendrum phlomidis is effective in ameliorating insulin resistance and visceral obesity induced by CD and Progesterone.

  1. Contribution of pollinators to seed production as revealed by differential pollinator exclusion in Clerodendrum trichotomum (Lamiaceae.

    Directory of Open Access Journals (Sweden)

    Ryota L Sakamoto

    Full Text Available A diverse assemblage of pollinators, such as bees, beetles, flies, and butterflies, will often visit a single plant species. However, evaluating the effect of several insects on fruit and seed production is difficult in plants visited by a variety of insects. Here, we analyzed the effect of three types of pollinators, Papilio spp., Macroglossum pyrrhosticta, and Xylocopa appendiculata on fruit and seed production in Clerodendrum trichotomum by using a flower visitor barrier experiment with nets of specific mesh sizes. As a result, fruit/flower and seed/ovule ratios were significantly lower under Papilio exclusion than under natural conditions. On the other hand, ratios were not significantly different between Papilio excluded and both Papilio and M. pyrrhosticta excluded treatments. Therefore, Papilio and X. appendiculata are effective pollinators, whereas M. pyrrhosticta, which was the most frequent visitor, of C. trichotomum, is not. From our observations of visiting behaviors, we believe that because M. pyrrhosticta probably promotes self- pollination, this species is a non-effective pollinator. This is the first study to separate and compare the contribution of various visitors to the reproductive success of a plant.

    The concept of Ayurvedic expert guided drug discovery and development is defined and put to test systematically for the first time in literature. Western Science has explored only ~5% of the approximately 25,000 species of higher plants for drug leads. The ancient medical science of Ayurveda has however employed a much larger spectrum of plants for clinical treatment. Clerodendrum viscosum (CV), a commonly growing weed in the Indian subcontinent has been employed by S. Nirmalananda (Ayurvedic expert) for the treatment of cervical cancer. Here we isolate and characterize a water extract fraction (Cv-AP) from the root of CV and evaluate its anticervical cancer cell bioactivity. Our results indicate that Cv-AP possesses pro-apoptotic, anti-proliferative, and anti-migratory activity in a dose-dependent fashion against cervical cancer cell lines. In contrast, primary fibroblasts (control healthy cells), when exposed to similar concentrations of this extract, fail to undergo apoptosis and remain relatively unaffected. These findings suggest that Clerodendrum viscosum (CV) is a readily available source of components with potent anti-cancer activity and selective bioactivity against cervical cancer cells. The major component in CV-AP was identified as a glycoprotein via SDS Page and Concanavalin-A binding studies. This study serves to illustrate that systematic collaboration with Ayurveda is a practical and powerful strategy in drug discovery and development. PMID:23387970

    International Nuclear Information System (INIS)

    In this study, we characterized some Xanthomonas sp. from rice rhizosphere soil by 16S rDNA sequence analysis and the potentiality tested of oil and extracts of Clerodendrum viscosum Vent. leaves against those isolated bacteria. The essential oil compositions were evaluated by GC-MS analysis and identified twenty four compounds as 94.37% of the total essential oil, where cyclohepta-1,3,5,-triene (16.07%), 2H-1,4-pyridoxazin-3(4H)-one (12.27%), L-carvenol (8.04%), p-cymene (9.15%), alpha-terpineol (7.98%), beta-sitosterol (6.76%), tyranton (6.42%), mesityl oxide (6.34%), gamma-terpinene (5.42%) and beta-linalool (3.74%) were the major constituents. According to the 16S rDNA sequences analysis, Hb28 and Xb43 isolates have shown the 100% similarity for Xanthomonas retroflexus and Xanthomonas theicola. In addition, isolates Ha18, Xb33 and Jb30 also have shown the maximum similarity of 98% for Xanthomonas sp. TB8-9-II, Xanthomonas campestris and Xanthomonas sp. BBCT38. Furthermore, in vitro studies showed that the oil have the inhibitory effect on Xanthomonas sp. TB8-9-II, X. campestris, X. retroflexus, Xanthomonas sp. BBCT38, and X. theicola, where the zone of inhibition and MIC values were 18.8 to 25.9 mm and 62.5 to 125 meu g ml/sup -1/, respectively. However, organic extracts showed the zone of inhibition and MIC values were 13.4 to 22.9 and 62.5 to 500 meu g ml-1, respectively. Our findings suggested that the essential oil and extracts of C. viscosum Vent. leaves might be the effective source to control Xanthomonas sp. biologically. (author)

    Full Text Available Inflammation is an important feature of many diseases. It is the response of a tissue to an injury, infection, irritation of foreign substance. In fact, it is a part of host defense, but when it is severe, it may be far worse than the diseases itself and in extreme condition, it may be too fatal also. There is an increasing demand for the medicinal plants in developing countries like India. Attention has to be given to assess the medicinal value of such plants to explore the potential drugs out of it. The aim of the study was to investigate acute anti-inflammatory activity of ethanolic extract of the leaves of Clerodendrum viscosum (EELCV by carrageenin induced paw oedema in Wistar Albino rats. Dried powdered leaves of Clerodendrum viscosum were subjected to soxhlet extraction by using 90% ethanol. Based on acute oral toxicity study according to Organization for Economic Cooperation and Development (OECD guidelines No. 423, three doses of the test drug were selected (75, 150 and 300 mg/kg p.o. Oral administration of EELCV at doses of 150 and 300mg/kg showed significant (p<0.01 and moderately significant acute anti-inflammatory activity (p<0.05 respectively by carrageenin induced paw oedema in Wistar Albino rats compared to control.

    Objective: Anti-obesity activity of alcoholic and methanolic extracts of roots of Clerodendrumphlomidis was evaluated against high fat diet (HFD) induced obesity in C57BL/6J female mice. Methods: Obesity was induced by feeding high fat diet for 13 weeks to C57BL/6J female mice and one group was kept on normal chow diet in order to evaluate the effect of Clerodendrumphlomidis on food intake, body weight changes, digestive enzyme activity, lipid metabolism, theromogenesis, adiposities diameter and histology of fat pad. Results: Among these two extracts methanolic extract of Clerodendrum phlomidis (MECP) have shown strong anti-obesity effect compare to alcoholic extract of Clerodendrum phlomidis (AECP). LD50 value was found to be more than 2000 mg/kg. Conclusions: MECP have shown more promising effects than AECP may be because of its multiple mechanisms. Anti-obesity activity produced by MECP is because of inhibition of pancreatic lipase activity which delays the intestinal absorption of dietary fat. Inhibition of pancreatic lipase activity was confirmed by in-vitro studies. MECP also containsβ-sitosterol in abundant amount which was confirmed by HPTLC analysis. Moreover flavonoid content in the plant has anorexic property. By this study we concluded that MECP is beneficial for the suppression of obesity and associated complications like T2DM.

    Results: Hematological analyses revealed that total WBC and leukocyte adhesion were not significantly different in control and extract-treated groups. Expression of IL-4 and IL-10 was significantly different in treated and control groups while expression of IL-12 was not significantly different. Cyclophosphamide-induced immunosuppression of the control group caused moderate to severe skin lesions while the rats in the extract-treated group did not sustain any skin lesions. All the rats in the cyclophosphamide-treated control group died after three months while 83.33% of the cyclophosphamide + plant extract received group survived, indicating the ability of the plant combination to alleviate the immunosuppression induced by cyclophosphamide. Conclusions: Treating with ethanolic extract combination of above plant species might exert their immunomodulatory effect via cytokine expression and can attenuate the immunosuppression induced by cyclophosphamide.

    @@ In the Ayurvedic, Siddha and other medical systems of India, products derived from herbs,used either as active ingredients or as adjuvants,hold paramount importance as alternative medi-cines.However, their standardization poses a great challenge.Correct identification of these drugs is often problematic in both their complete form as well as in powder form, since these medicinal plants are known by a variety of vernacular names and frequently many medicinal plants share the same name.Comparative thin-layer chromatography (co-TLC) with chemical or biological marker compounds can be used to standardize raw materials.Moreover, due to its simplicity, accuracy, cost effectiveness and rapidity, TLC is often used as an alternative to other chromatographic tech-niques for quantifying plant products.

    Full Text Available A total of 119 new chorological reports are given for 7 red-listed species, namely, Dryopteris aemula, Hymenophyllum tunbrigense, Prunus lusitanica, Soldanella villosa, Stegnogramma pozoi, Vandenboschia speciosa, and Veratrum album. Comments on their ecology and local distribution maps are provided. The number of subpopulations of S. villosa (52 and T. speciosum (38 found is remarkable. In several streams, the gametophyte phase of T. speciosum, rarely reported in the Iberian Peninsula, exceeds the sporophyte generation in number of individuals, which probably has important conservation and genetic diversity implications. It is proposed that the Urumea Site of Communitary Interest be extended to cover the streams that discharge into it, or alternatively, threatened plant microreserves be established at the Apaizeta, Azketa and Kartola streams.

    Several species within the genus Theobroma have particularly high economic value, including T. cacao and T. grandiflorum. Other species in this genus, such as T. speciosum and T. subincanum, have potential value for use in the conservation of genetic diversity in breeding programs. These latter species could also be domesticated or improved to produce commercial products. Using 13 simple sequence repeat loci, the population structure and genetic diversity of T. speciosum and T. subincanum natural populations in the Juruena National Park, Mato Grosso State, Brazil, was studied. We sampled all individuals of each species (N = 25) present inside a designated research area established by the Program for Research on Biodiversity. The average number of alleles per locus was 5 for T. speciosum and 6.69 for T. subincanum, with average PIC values above 0.5 in both species. All evaluated individuals varied genetically. Seeds from the individuals analyzed will be useful for the development of germplasm banks and for establishment of breeding programs. PMID:26345977

    Full Text Available Abstract Background Six plants from Thailand were evaluated for their cytotoxicity and apoptosis induction in human hepatocarcinoma (HepG2 as compared to normal African green monkey kidney epithelial cell lines. Methods Ethanol-water crude extracts of the six plants were tested with neutral red assay for their cytotoxicity after 24 hours of exposure to the cells. Apoptotic induction was tested in the HepG2 cells with diamidino-2-phenylindole staining. DNA fragmentation, indicative of apoptosis, was analyzed with agarose gel electrophoresis. Alkylation, indicative of DNA damage, was also evaluated in vitro by 4-(4'-nitrobenzyl pyridine assay. Results The extract of Pinus kesiya showed the highest selectivity (selectivity index = 9.6 and potent cytotoxicity in the HepG2 cell line, with an IC50 value of 52.0 ± 5.8 μg/ml (mean ± standard deviation. Extract of Catimbium speciosum exerted cytotoxicity with an IC50 value of 55.7 ± 8.1 μg/ml. Crude extracts from Glochidion daltonii, Cladogynos orientalis, Acorus tatarinowii and Amomum villosum exhibited cytotoxicity with IC50 values ranging 100-500 μg/ml. All crude extracts showed different alkylating abilities in vitro. Extracts of P. kesiya, C. speciosum and C. orientalis caused nuclei morphological changes and DNA laddering. Conclusion The extracts of C. speciosum, C. orientalis and P. kesiya induced apoptosis. Among the three plants, P. kesiya possessed the most robust anticancer activity, with specific selectivity against HepG2 cells.

    Full Text Available Some 226 species of native orchids have been recorded in Singapore. However, of these 178 are considered to be extinct, and only five are common. The orchid conservation programme aims to monitor existing species, explore ways to conserve their germplasm, and increase their number for subsequent re-introduction into appropriate habitats, including roadside trees, parks and nature areas. From 1999 to 2008, we carried out experiments and have successfully propagated and re-introduced 5 species of native orchids, namely Grammatophyllum speciosum Blume, Bulbophyllum vaginatum Rchb.f., Bulbophyllum membranaceum Teijsm. and Binn., Cymbidium finlaysonianum Lindl. and Cymbidium bicolor Lindl. spp. pubescens (Lindl. Du Puy and Cribb. More than 80% of the plants are growing well and all that have survived have flowered. From 2009 to 2012, we expanded our reintroduction efforts by planting fifteen species: Bulbophyllum blumei (Lindl. J.J.Sm., Bulbophyllum medusae (Lindl. Rchb.f., Bulbophyllum membranaceum Teijsm. and Binn., Bulbophyllum purpurascens (T. and B.

One of our goals is that the reintroduced species would act as catalysts for the restoration of at least part of the original ecosystem. For example, pollinators may be attracted to sites where orchids have been re-introduced. Subsequently, orchid seeds that are produced from naturally pollinated flowers may be blown to the safe sites where appropriate mycorrhizal fungi are present; thus making germination and subsequent establishment of natural populations in

    Sakamoto, Ryota L.; Morinaga, Shin-Ichi

    2013-09-01

    Pollinators deposit pollen grains on stigmas and remove pollen grains from anthers. The mechanics of these transfers can now be quantified with the use of high-speed video. We videoed hawkmoths, carpenter bees, and swallowtail butterflies pollinating Clerodendrum trichotomum. The number of grains deposited on stigmas did not vary significantly with the number of times pollinators contacted stigmas. In contrast, pollen removal from the anthers increased significantly with the number of contacts to anthers. Pollen removal varied among the three types of pollinators. Also, the three types carried pollen on different parts of their bodies. In hawkmoths and carpenter bees, a large number of contacted body part with anthers differed significantly from the body part that attached a large number of pollen grains. Our results indicate that a large number of contacts by pollinators does not increase either the male or female reproductive success of plants compared to a small number of contacts during a visit.

    Full Text Available The biological synthesis of nanoparticles using plant extracts plays an important role in the field of nanotechnology. In this study, rapid, simple approach was applied for synthesis of silver nanoparticles using , Clerodendrum infortunatum, Mucuna interrupta, Phlogancanthus thyrsiflorus and Sansevieria trifasciata aqueous leaf extract. The plant extract acts both as reducing agent as well as capping agent. To identify the compounds responsible for reduction of silver ions, the functional groups present in plant extract were investigated by FTIR. Various techniques used to characterize synthesized nanoparticles are Scanning Electron Microscopy (SEM, Atomic Force Microscopy (AFM and UV–Visible spectrophotometer. Results confirmed that this protocol was simple, rapid, one step, eco-friendly, non-toxic and might be an alternative conventional physical/chemical methods. Conversion of silver nanoparticles takes place at room temperature without the involvement of any hazardous chemicals.

    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

    Full Text Available Abstract Background Around the turn of this century, the oil yield and chemical composition of Australian Leptospermum species was analysed. Since that time, research has been focused on their use as phytomedicines. The oil yield and composition of essential oils from Australian Leptospermum species directly impacts their commercialisation for medicinal use. Results The essential oils from Leptospermum (L. juniperinum, L. laevigatum, L. liversidgei, L. polygalifolium, L. semibaccatum, L. speciosum, L. trinervium and L. whitei have been examined from specimens in the Sunshine Coast (Queensland and Northern Rivers (New South Wales Regions. Both chemotypes of L. liversidgei were observed. However, only chemotype II of L. semibaccatum and chemotype I of L. trinervium were identified. The only subspecies observed of L. polygalifolium was L. polygalifolium wallum. Conclusions L. liversidgei chemotypes I and II have the potential for phytomedical use as antibacterial or anti-inflammatory agents. Chemotype I has the potential for use as an insect repellent and chemotype II may provide antifungal activity.

    Studies of mangrove species's reflectance characteristic are important in order to have a deep understanding of mangrove vegetation. In this paper, the significant wavelengths which can be used to separate the six mangrove species at Matang Mangrove Forest Reserve (MMFR), Perak were examined. The investigated mangrove species comprise of Rhizophora apiculata, Acrostichum aurem, Acrostichum speciosum, Acanthus ilicifolius, Ceriops tagal and Sonneratia ovata. In-situ spectral reflectance data of six mangrove species's leaf were obtained using ASD FieldSpec3 spectroradiometer and were statistically tested using SPSS program. First, wavelengths which exhibited significant differences (P value<0.05) among the mean reflectance of six mangrove species were identified using a series of one way ANOVA. Second, the identified wavelengths were further analyzed using canonical stepwise discriminant analysis and 26 significant wavelengths were obtained which can be utilized to distinguish among the six mangrove species. In conclusion, each mangrove species in MMFR have it own unique reflectance properties and these characteristic enable the mangrove species can be discriminated among each other under proper analysis and data extraction.

  18. Leaf and floral heating in cold climates: do sub-Antarctic megaherbs resemble tropical alpine giants?

    Full Text Available High latitude and altitude floras are characterized by low-statured, small, wind-pollinated plants, which mainly reproduce by self-pollination or asexual reproduction. However, at odds with this are some sub-Antarctic islands that have plant species with giant growth forms and large, brightly coloured flowers which require insect visitation for pollination. The size, colour and shape of the inflorescences and leaves of these megaherbs suggest thermal benefits similar to giant tropical alpine plants of equatorial Africa, South America and Hawaii. We evaluated whether heating occurs in sub-Antarctic megaherbs, and to what extent it is related to environmental variables. We measured leaf and inflorescence temperature in six sub-Antarctic megaherb species on Campbell Island, latitude 52.3°S, New Zealand Biological Region. Using thermal imaging techniques, in combination with measurement of solar radiation, ambient air temperature, wind speed, wind chill and humidity, we assessed environmental influences on leaf and floral heating. We found that leaf and inflorescence temperatures of all megaherbs were higher than simultaneously measured ambient temperatures. Greatest heating was seen in Pleurophyllum speciosum, with observed leaves 9°C higher, and inflorescences nearly 11°C higher, than ambient temperature. Heating was highly correlated with brief, unpredictable periods of solar radiation, and occurred most rapidly in species with hairy, corrugated leaves and darkly pigmented, densely packed inflorescences. This is the first evidence that floral and leaf heating occurs in sub-Antarctic megaherbs, and suggests that leaf hairiness, flower colour and shape could provide thermal benefits like those seen in tropical alpine megaherbs.

    Full Text Available Abstract Background Diseases caused by microorganisms and parasites remain a major challenge globally and particularly in sub-Saharan Africa to man and livestock. Resistance to available antimicrobials and the high cost or unavailability of antimicrobials complicates matters. Many rural people use plants to treat these infections. Because some anthelmintics e.g. benzimidazoles also have good antifungal activity we examined the antifungal activity of extracts of 13 plant species used in southern Africa to treat gastrointestinal helminth infections in livestock and in man. Methods Antifungal activity of acetone leaf extracts was determined by serial microdilution with tetrazolium violet as growth indicator against Aspergillus fumigatus, Cryptococcus neoformans and Candida albicans. These pathogens play an important role in opportunistic infections of immune compromised patients. Cytotoxicity was determined by MTT cellular assay. Therapeutic indices were calculated and selectivity for different pathogens determined. We proposed a method to calculate the relation between microbicidal and microbistatic activities. Total activities for different plant species were calculated. Results On the whole, all 13 extracts had good antifungal activities with MIC values as low as 0.02 mg/mL for extracts of Clausena anisata against Aspergillus fumigatus and 0.04 mg/mL for extracts of Zanthoxylum capense, Clerodendrum glabrum, and Milletia grandis, against A. fumigatus. Clausena anisata extracts had the lowest cytotoxicity (LC50 of 0.17 mg/mL, a reasonable therapeutic index (2.65 against A. fumigatus. It also had selective activity against A. fumigatus, an overall fungicidal activity of 98% and a total activity of 3395 mL/g against A. fumigatus. This means that 1 g of acetone leaf extract can be diluted to 3.4 litres and it would still inhibit the growth. Clerodendrum glabrum, Zanthoxylum capense and Milletia grandis extracts also yielded promising results

    Soil and water contaminated with arsenic (As) pose a major environmental and human health problem in Bangladesh. Phytoremediation, a plant-based technology, may provide an economically viable solution for remediating the As-polluted sites. The use of indigenous plants with a high tolerance and accumulation capacity for As may be a very convenient approach for phytoremediation. To assess the potential of native plant species for phytoremediation, plant and soil samples were collected from four As-contaminated (groundwater) districts in Bangladesh. The main criteria used for selecting plants for phytoremediation were high bioconcentration factors (BCFs) and translocation factors (TFs) of As. From the results of a screening of 49 plant species belonging to 29 families, only one species of fern (Dryopteris filix-mas), three herbs (Blumea lacera, Mikania cordata, and Ageratum conyzoides), and two shrubs (Clerodendrum trichotomum and Ricinus communis) were found to be suitable for phytoremediation. Arsenic bioconcentration and translocation factors > 1 suggest that these plants are As-tolerant accumulators with potential use in phytoextraction. Three floating plants (Eichhornia crassipes, Spirodela polyrhiza, and Azolla pinnata) and a common wetland weed (Monochoria vaginalis) also showed high BCF and TF values; therefore, these plants may be promising candidates for cleaningup As-contaminated surface water and wetland areas. The BCF of Oryza sativa, obtained from As-contaminated districts was > 1, which highlights possible food-chain transfer issues for As-contaminated areas in Bangladesh. PMID:18709925

    Faced with critical shortages of staff, long queues, and stigma at public health facilities in Livingstone, Zambia, persons who suffer from HIV/AIDS-related diseases use medicinal plants to manage skin infections, diarrhoea, sexually transmitted infections, tuberculosis, cough, malaria, and oral infections. In all, 94 medicinal plant species were used to manage HIV/AIDS-related diseases. Most remedies are prepared from plants of various families such as Combretaceae, Euphorbiaceae, Fabaceae, and Lamiaceae. More than two-thirds of the plants (mostly leaves and roots) are utilized to treat two or more diseases related to HIV infection. Eighteen plants, namely, Achyranthes aspera L., Lannea discolor (Sond.)

Wight and Arn., Abrus precatorius L., Hoslundia opposita Vahl., Clerodendrum capitatum (Willd.) Schumach., Ficus sycomorus L., Ximenia americana L., and Ziziphus mucronata Willd., were used to treat four or more disease conditions. About 31% of the plants in this study were administered as monotherapies. Multiuse medicinal plants may contain broad-spectrum antimicrobial agents. However, since widely used plants easily succumb to the threats of overharvesting, they need special protocols and guidelines for their genetic conservation. There is still need to confirm the antimicrobial efficacies, pharmacological parameters, cytotoxicity, and active chemical ingredients of the discovered plants. PMID:27069489

    Full Text Available North-East India represents a unique ecosystem with treasured medicinal plant wealth closely related with Folk medicines. A large number of plants having medicinal properties and their folk uses have remained confined to the natives of this region. The tribal community of Jonai, Assam was explored to expose the indigenous herbal remedy for malaria. Sixteen antimalarial plants belonging to 13 families were reported. The analysis revealed highest fidelity level (FL value for Ajuga integrifolia (100% followed by Ricinus communis (94%, Alstonia scholaris (88%, Oroxylum indicum (86% and Achyranthes aspera (82%. The percentage of respondent’s knowledge (PRK about anti-malarial plants showed Alstonia scholaris as the most commonly known antimalarial species (53% within this region. Preference ranking (PR unveiled eight species to be very effective against malarial parasite, which includes Allium sativum, Artemisia indica, Azadirachta indica, Carica papaya, Clerodendrum glandulosum, Ocimum tenuiflorum, Oroxylum indicum, Piper longum and Piper nigrum. All medicine preparations are made using water as the medium and are orally administered in the form of crude extract, powder, juice and decoction. Overall analysis suggested Ajuga integrifolia, Achyranthes aspera, Alstonia scholaris, Artemisia indica, Oroxylum indicum and Ricinus communis to be used for the development of novel, economical, effective and ecofriendly herbal formulations for healthcare management.

  5. Determination of potentially toxic heavy metals in traditionally used medicinal plants for HIV/AIDS opportunistic infections in Ngamiland District in Northern Botswana

    International Nuclear Information System (INIS)

    Highlights: ► Determine As, Cr, Ni and Pb in traditional plants used to treat HIV/AIDS opportunistic infections. ► Metal levels and provisional tolerable weekly intake levels lower than WHO permissive maximum levels. ► Cr > Pb > As > Ni. ► Consumption of traditional medicinal plants are not health-comprising with respect to metals. - Abstract: The determination of four potentially toxic heavy metals, arsenic, chromium, lead and nickel in twelve plant species used for the treatment of perceived HIV and AIDS-associated opportunistic infections by traditional healers in Ngamiland District in Northern Botswana, a metal mining area, was carried out using atomic absorption spectrometry. The medicinal plants; Dichrostachys cinerea, Maerua angolensis, Mimusops zeyheri, Albizia anthelmintica, Plumbago zeylanica, Combretum imberbe, Indigofera flavicans, Clerodendrum ternatum, Solanum panduriforme, Capparis tomentosa, Terminalia sericea and Maytenus senegalensis contained heavy metals in varying quantities: arsenic 0.19–0.54 μg g−1, chromium 0.15–1.27 μg g−1, lead 0.12–0.23 μg g−1 and nickel 0.09–0.21 μg g−1 of dry weight. Chromium was found to be the most abundant followed by arsenic and lead. Nickel was undetectable in nine plant species. M. senegalensis contained the largest amounts of arsenic, chromium and lead. All metals determined were below the WHO permissive maximum levels. The possible maximum weekly intakes of the heavy metals following treatment regimes were insignificant compared to the provisional tolerable weekly intake levels recommended by WHO and the Joint FAO/WHO Expert Committee on Food Additives. This suggests that heavy metal exposure to patients originating from consumption of traditional medicinal plant preparations is within non health-compromising limits.

    Tzu-Yu Lin

    Full Text Available An excessive release of glutamate is considered to be a molecular mechanism associated with several neurological diseases that causes neuronal damage. Therefore, searching for compounds that reduce glutamate neurotoxicity is necessary. In this study, the possibility that the natural flavone acacetin derived from the traditional Chinese medicine Clerodendrum inerme (L. Gaertn is a neuroprotective agent was investigated. The effect of acacetin on endogenous glutamate release in rat hippocampal nerve terminals (synaptosomes was also investigated. The results indicated that acacetin inhibited depolarization-evoked glutamate release and cytosolic free Ca(2+ concentration ([Ca(2+]C in the hippocampal nerve terminals. However, acacetin did not alter synaptosomal membrane potential. Furthermore, the inhibitory effect of acacetin on evoked glutamate release was prevented by the Cav2.2 (N-type and Cav2.1 (P/Q-type channel blocker known as ω-conotoxin MVIIC. In a kainic acid (KA rat model, an animal model used for excitotoxic neurodegeneration experiments, acacetin (10 or 50 mg/kg was administrated intraperitoneally to the rats 30 min before the KA (15 mg/kg intraperitoneal injection, and subsequently induced the attenuation of KA-induced neuronal cell death and microglia activation in the CA3 region of the hippocampus. The present study demonstrates that the natural compound, acacetin, inhibits glutamate release from hippocampal synaptosomes by attenuating voltage-dependent Ca(2+ entry and effectively prevents KA-induced in vivo excitotoxicity. Collectively, these data suggest that acacetin has the therapeutic potential for treating neurological diseases associated with excitotoxicity.

    Background & objectives: Phlebotomus argentipes (Diptera: Psychodidae), the established vector for kala-azar is presently being controlled by indoor residual spray of DDT in kala-azar endemic areas in India. Search for non-hazardous and non-toxic biodegradable active molecules from botanicals may provide cost-effective and eco-friendly alternatives to synthetic insecticides. The present study was aimed at evaluating various plant extracts from endemic and non-endemic areas of Bihar for their insecticidal activity against sandfly to identify the most effective plant extract. Methods: Bio-assay test was conducted with larvae and adult of P. argentipes with different plant extracts collected in distilled water, hexane, ethyl acetate, acetone and methanol. Thin layer chromatography (TLC), column chromatography and high performance liquid chromatography (HPLC) were conducted for detection of active molecules. Results: Adults and larvae of sandflies exposed to the aqueous extract of Nicotiana tabacum resulted in 100 per cent mortality. The hexane extract of Clerodendrum infortunatum was found to kill 77 per cent adults but was ineffective against larvae. Bio-assay test of the ninth fraction (hexane extract-methanol phase) separated by column chromatography was found to be 63 per cent effective. The purple spot on the TLC of this fraction indicated the presence of a diterpenoid. HPLC of this fraction detected nine compounds with two peaks covering 20.44 and 56.52 per cent areas with retention time of 2.439 and 5.182 min, respectively supporting the TLC results. Interpretation & conclusions: The column separated 9th fraction of C. infortunatum extract was found to be effective in killing 63 per cent of adult P. argentipes. Compounds of this fraction need to be evaluated further for identification and characterization of the active molecule by conducting individual bio-assay tests followed by further fractionation and HPLC. Once the structure of the active molecule is

    Full Text Available Ten natural dye yielding and two mordant plants were biochemically analyzed. Though natural dyes are widely used, information about the active principles responsible for dyeing is hardly available. In the present experiment, total chlorophyll, carotinoids, tannins, phenolics, flavonoids and curcumin were determined among the dye yielding plants, while K, S, P, Ca, Mg, Mn, Zn, Fe, Cu and Co were determined in the case of mordant plants. In Bixa orellana, used for yellow dyeing, the carotinoid content was 163.11 mg g-1 and in Clerodendrum chinense and Datura stramonium, which were used for green colouring, total chlorophyll content of 10.29 mg and 11.83 mg g-1 was recorded. Curcumin content responsible for orange colouring in Curcuma domestica was 27.7 mg g-1 while flavonoid content in Solanum nigrum and Terminalia chebula, which were used for brown, brown to black dyes was 24.89 and 21.73 mg g-1. Among the plants used for dyeing different colours, Punica granatum and Parkia timoriana were found to contain higher amounts of total phenols and bound phenols by recording 681.2 mg g-1 and 287.6 mg g-1 total phenols and 151.6 mg g-1 and 130.2mg g-1 bound phenols, while higher amounts of orthodihydric phenols and tannins were recorded in Punica granatum and Strobilanthes flaccidifolius by recording 20.11mg g-1 and 9.54mg g-1 orthodihydric phenols and 675.57mg g-1 and 648.12 mg g-1 tannins, respectively. In case of the plants used as mordant, higher contents of Ca, Mg, K, Zn, Fe and Mn were detected in Achyranthes aspera, while higher amounts of P, Fe and Cu were recorded in Garcinia xanthochymus.

    Full Text Available Tea is a popular beverage made from the leaves of evergreen shrub or tree Camellia sinensis, under the family Theaceae. Tea plant is subjected to the attack of insects, mites, nematodes and some plant pathogenic diseases. Tea production is greatly hindered due to thesemaladies. About 10-15% crop loss occurred by these pests per annum. In severe cases, it would be 100%. To combat these problems different groups of pesticides have been used in the tea fields since 1960. As tea is a consumable commodity, the effect of residue of pesticides in made tea is harmful to human health. In this context, biopesticides are being considered as environmentally safe, selective, biodegradable, economical and renewable alternatives for use in IPM programmes. Biopesticides are natural plant products and may be grown by the planters with minimum cost and extracted by indigenous methods.Biopesticides are secondary metabolites, which include alkaloids, terpenoids, phenolics, and minor secondary chemicals. It is estimated that as many as 2121 plant species have been reported to posses’ pest control properties. Botanicals like neem, ghora-neem, mahogoni,karanja, adathoda, sweet flag, tobacco, derris, annona, smart weed, bar weed, datura, calotropis, bidens, lantana, chrysanthemum, artemisia, marigold, clerodendrum, wild sunflower and many others may be grown by planters with minimum expense and extracted by indigenous methods. These botanical materials can be used as an alternative to chemical pesticides. These botanical extracts will help in controlling major pests of tea such as Helopeltis, red spider mite, aphids, thrips, jassid, flushworm, termites, nematodes etc. Thepresent note reviews the information of most widely available indigenous plants that may be used for the control of insect pests of tea as a component of IPM.

    A high-performance liquid chromatographic method was developed for quantitative analysis of arbutin. The arbutin was separated on an ODS Hypersil C(18) column with a mobile phase of water:methanol:0.1 M hydrochloric acid (89:10:1, v/v/v). The level of arbutin was measured by means of UV detection at 222 nm. The optimum conditions for arbutin quantitative analysis were investigated. The calibration curve was found to be linear up to 1,000 microg/ml(-1) of arbutin concentration, and the working calibration curve for arbutin determination over the range 0.5-30.0 microg/ml(-1) of arbutin (r(2)=0.9999) was established. The relative standard deviations for intraday and interday were found to be 0.98% and 1.15%, respectively. A detection limit (3sigma) and quantitation limit (10sigma) of 0.02 microg/ml(-1) and 0.2 microg/ml(-1), respectively, and a mean percentage recovery of the spiked arbutin of 99.88 +/- 1.12% were obtained. The proposed method has been applied to the determination of arbutin in commercial skin-whitening creams (Arbuwhite cream, Super Whitening cream, and Shiseido cream) with average contents of 7.60, 5.30, and 57.90 mg/g(-1), respectively. It was also applied to the determination of arbutin in medicinal plant extracts from Betula alnoides Buch. Ham., Clerodendrum petasites S. Moore, Curculigo latifolia Dryand. Var. latifolia, and Hesperethusa crenulata (Roxb.) Roem, levels of which were found to be 3.50, 1.50, 1.10, and 0.12 microg/g(-1), respectively (no article reported in the literature about arbutin analysis). The proposed HPLC method is rapid, simple, and selective for routine analysis. PMID:17342266

    Microorganisms associated with medicinal plants are of interest as the producers of important bioactive compounds. To date, the diversity of culturable endophytic actinomycetes associated with medicinal plants is in its initial phase of exploration. In this study, 42 endophytic actinomycetes were isolated from different organs of seven selected medicinal plants. The highest number of isolates (n = 22, 52.3%) of actinomycetes was isolated from roots, followed by stems (n = 9, 21.4%), leaves (n = 6, 14.2%), flowers (n = 3, 7.1%), and petioles (n = 2, 4.7%). The genus Streptomyces was the most dominant among the isolates (66.6%) in both the locations (Dampa TRF and Phawngpuii NP, Mizoram, India). From a total of 42 isolates, 22 isolates were selected for further studies based on their ability to inhibit one of the tested human bacterial or fungal pathogen. Selected isolates were identified based on 16S rRNA gene analysis and subsequently the isolates were grouped to four different genera; Streptomyces, Brevibacterium, Microbacterium, and Leifsonia. Antibiotic sensitivity assay was performed to understand the responsible antimicrobials present in the isolates showing the antimicrobial activities and revealed that the isolates were mostly resistant to penicillin G and ampicillin. Further, antimicrobial properties and antibiotic sensitivity assay in combination with the results of amplification of biosynthetic genes polyketide synthase (PKS-I) and non-ribosomal peptide synthetase (NRPS) showed that the endophytic actinomycetes associated with the selected medicinal plants have broad-spectrum antimicrobial activity. This is the first report of the isolation of Brevibacterium sp., Microbacterium sp., and Leifsonia xyli from endophytic environments of medicinal plants, Mirabilis jalapa and Clerodendrum colebrookianum. Our results emphasize that endophytic actinomycetes associated with medicinal plants are an unexplored resource for the discovery of biologically active

    Full Text Available The associations in a northern tropical karst seasonal rainforest plot in Nonggang National Nature Reserve were classified using the multivariate regression tree method in conjunction with the relative elevation, slope, aspect, convexity, and the importance value of species. The results showed that the relative elevation and aspect were critical for the spatial distribution of species. The forest community of the Nonggang plot was divided into eight associations. They were as follows: (A Ardisia thyrsiflora–Sterculia monosperma–Saraca dives association, distributed primarily at the edge of valley bottoms with high humidity and soil moisture; (B Ficus hispida–Sterculia monosperma–Caryota obtusa association, distributed primarily at the valley bottom where seasonal flooding occurs and the soil moisture and humidity are high; (C Catunaregam spinosa–Vitex kwangsiensis–Excentrodendron tonkinense association, distributed primarily on south-facing slopes at lower elevations with slight drought and greater sunlight; (D Clerodendrum wallichii–Sterculia monosperma–Cychidendron guangxiensis association, distributed primarily on shaded slopes at lower elevations with moderate soil moisture and less sunlight; (E Aglaia odorata–Cleistanthus sumatranus–Excentrodendron tonkinense association, distributed primarily on upper and middle half-shaded slopes with slight drought; (F Walsura robusta–Cleistanthus sumatranus-Excentrodendron tonkinense association, distributed primarily on steep half-sunny slopes with slight drought; (G Chionanthus ramiflorus–Vitex kwangsiensis–Excentrodendron tonkinense association, distributed mainly on passes with a gentle slope, moderate soil moisture, and less sunlight; (H Clausena dunniana–Boniodendron minius–Excentrodendron tonkinense association, distributed mainly at the top of the mountain and in the surrounding areas, where the longest sunlight periods and the greatest extent of bare rock are

    Full Text Available An ethnobotanical study of medicinal plants was conducted in and around Fiche District, North Shewa Zone of Oromia Region, Ethiopia from September 2011 to January 2012. Ten kebeles were selected from North to South and East to West directions of Fiche District and its surroundings by purposive sampling method. Six informants including one key informant were selected from each kebele for data collection by using printed data collection sheets containing, semi-structured interview questions, group discussion and guided field walk. The plant specimens were identified by using taxonomic keys in the Floras of Ethiopia and Eritrea. The data were analysed using descriptive statistics; informant consensus factor and fidelity level using MS-Excel 2010. Totally, 155 medicinal plants belonging to 128 genera and 65 families were recorded. Most medicinal plants (72.9% were used for human healthcare in which Lamiaceae was dominant (11% in which Ocimum lamiifolium, Otostegia integrifolia and Leonotis ocymifolia were the most common species. Herbs were dominant (43.87% flora followed by shrubs (35.48%. The most frequently used plant parts for remedial preparation were leaves (38.1% followed by roots (14.8% and others. Fresh plant parts were used mostly (47.7% followed by dried (13.5% and the remaining (38.7% either in fresh or dried. Among the preparations, crushing was the dominant (21.3% form followed by squeezing (16.1%. The remedial administration was mostly oral (38.7% followed by dermal (29%. The highest (88% ICF was associated with intestinal parasites followed by emergency diseases (82%. The FL of Actiniopteris semiflabellata, Plantago lanceolata, Capparis tomentosa, and Clerodendrum myricoides was calculated 100% irrespective of diseases. In conclusion, rich diversity of floras were mostly practiced in crude form and to prevent extinction of medicinal plants due to unsustainable anthropogenic activities, local communities need to give attention for in
