Insecticidal effects of essential oils extracted from aromatic plants on Ceratitis capitata (Wied.) in Lebanon

The authors have developed a complex of activation methods of analysis using a nuclear reactor (nuclear activation analysis) and a cyclotron (charged-particle activation analysis). The methods have been used to determine the concentrations of more than 20 elements in five medicinal plants native to Uzbekistan: Syrian rue (Peganum harmala L.), plantain (Plantago lanceolata), peppermint (Mentha piperata L.), sage (Salvia officinalis L.), and ziziphora (Ziziphora bungeana Yur.). The results of radio-activation analysis were compared with the results of standard spectral analysis performed in another laboratory and the accuracy of the procedures developed was evaluated on the basis of the results.

Effect on the Quality Characteristics of Korean Traditional Wines with the Addition of Rosemary (Rosmarinus officinalis L.)

We reported the radio-protective effect of DTT. The treatment of DTT increased cell survival after gamma-irradiation, decreased in the frequencies of micronucleus, and reduction in DNA fragmentation and apoptotic cells. Induction of apoptosis after UV-C irradiation was revealed by the changes in the relative cell death, increase in the relative amount of apoptotic cells, and the induction of DNA fragmentation. About 100 medicinal plants were purchased and methanol extract samples were prepared. Radio-protective and radio-sensitizing activities of these samples were screened. Seven samples showed above 20% radio-protective activities: Salvia miltiorrhiza, Areca catechu, Cornus officinalis, Alpiniae officinari rhizoma, Meliae fructus, Alpiniae katsumadaii semen, Betulae cortex. Acanthopanax sessiliflous showed the highest radio-sensitizing effect and 10 other samples revealed moderate activities: Melia japonica, Agastache rugosa, Platycodon ...

Metabolite profiling of sucrose effect on the metabolism of Melissa officinalis by gas chromatography-mass spectrometry

British Library Electronic Table of Contents (United Kingdom)

The effect of sugar on plant metabolism, which is known to be similar to hormone-like signaling, was metabolomically studied using Melissa officinalis (lemon balm). The metabolite profiles of M. officinalis treated with sucrose were analyzed by gas chromatography-mass spectrometry (GC-MS) and principal component analysis (PCA). A total of 64 metabolites from various chemical classes including alcohols, amines, amino acids, fatty acids, inorganic acids, organic acids, phosphates, and sugars were identified by GC-MS. Three groups treated with different sucrose concentrations were clearly separated by PCA of their metabolite profiles, indicating changes in the levels of many metabolites depending on the sucrose concentration. Metabolite profiling revealed that treatment with a higher sucrose ...

Seasonal variations in biochemical composition of Sepia officinalis (Mollusca) from the Mediterranean waters off Alexandria, Egypt

ANTIMICROBIAL ACTIVITY OF MAGNOLIA OFFICINALIS EXTRACTS IN VITRO AND ITS EFFECTS ON THE PRESERVATION OF CHILLED MUTTON

The biochemical compositions of 465 Sepia officinalis mantles from the Mediterranean waters off Alexandria Egypt, were studied from September 1989 to August 1990. Water contents of males and females were not significantly different, and followed the same pattern showing a sharp decrease in summer. Lipid contents of males and females were similar, showing two peaks in summer and autumn. A clear reverse relationship between water and lipid contents was found. Protein and ash contents showed irregular patterns. Protein contents were increased in early spring and mid-summer. The relationship between body compositions and mantle size, gonads maturation and environmental conditions was discussed.

Abstract The inhibitory effect of the extract from Magnolia officinalis (MOE) against L. monocytogenes, S. faecalis, E. coli, S. typhimurium, S. aureus and B. anthracis by paper-diffusion methods and the characterization of the mutton immersed in different concentrations of the MOE during storage were evaluated in this paper. The results showed that MOE could significantly inhibit the growth of S. aureus, S. faecalis, B. anthracis and E. coli, and their MIC was 0.02-mg/mL, 0.03-mg/mL, 0.05-mg/mL and 0.10-mg/mL, respectively. MOE showed weak inhibition for the S. typhimurium. The mutton treated with 2%, 4% and 6% MOE resulted in suppression in the increase of total volatile base nitrogen, thiobarbituric acid reactive substance, and the growth of Enterobacteriaceae, Pseudomonas. The cooled m...

Adipose tissue plays an essential role in energy homeostasis as a metabolic and endocrine organ. Accordingly, adipocytes are emerging as a major drug target for obesity and obesity-mediated metabolic syndrome. Dysfunction of enlarged adipocytes in obesity is involved in obesity-mediated metabolic syndrome. Adipocytokines, such as adiponectin released from small adipocytes, are able to prevent these disorders. In this study, we found that honokiol, an ingredient of Magnolia officinalis used in traditional Chinese and Japanese medicines, enhanced adipocyte differentiation in 3T3-L1 preadipocytes. Oil Red O staining showed that treatment with honokiol in the presence of insulin dose-dependently increased lipid accumulation in 3T3-L1 preadipoyctes although its activity was weak compared with r...

Development of a greenhouse-type solar dryer for medicinal plants and herbs

Comparative profiling of the transcriptional response to soybean cyst nematode infection of soybean roots by deep sequencing

The economy of medicinal plant production is burdened considerably by the energy costs of drying. To substitute fossil energy, a solar heated dryer was developed, taking a plastic film greenhouse as superstructure to lower the initial costs. The solar air heaters, being incorporated into the roof, consist of a black absorber tissue, which is placed between the transparent cover of the greenhouse and an insulating air-bubble foil. To obtain a modular design, the system is structured along the ridge into segments of 2 m width. Each segment forms an independent solar air heater/batch dryer unit and is operated by a fan with a power consumption of 500 W. A prototype was tested in Yugoslavia, drying mint, sage and hops.

To gain insight into the changes in the transcriptome of soybean roots during soybean cyst nematode (SCN) infection, we conducted genome-wide gene expression profiling using serial analysis of gene expression (SAGE) combined with Solexa sequencing. More than 3 million tags were generated from the SCN-infected and uninfected roots, and 366941 and 314591 clean UniTags were obtained from SCN-infected and uninfected samples, respectively. In the SCN-infected sample, 48249 UniTags represented 18114 reference genes. In the uninfected control, 46290 UniTags represented 19323 reference genes. Comparison of tag frequencies identified 1405 genes that were expressed at greater levels in SCN-infected roots than in uninfected roots, and 1191 genes that were expressed at lower levels. Quantitative real-...

Development of enhanced radioprotectors - Biochemical and molecular genetical approaches on the radioprotective mechanism of natural products

Neurite outgrowth effect of 4-O-methylhonokiol by induction of neurotrophic factors through ERK activation.

To identify radio-protective agent candidate among medicinal plants and to elucidate the mechanism of action of the candidate material by using modern biochemical and molecular biological methods, we screened radio-protective activity among 48 medicinal plants. Seven samples showed above 20% protective activities against oxidative cell damage: Euryale ferox, Glycyrrhiza uralensis, Salvia miltiorrhiza, Eucomia ulmoides, Paeonia suffruticosa, Spirodela polyrrhiza, and Nelumbo nucifera. We also screened for oxidative stress sensitizing activity among other 51 medicinal plants. Among those samples, 11 samples showed good sensitizing effect; Melia azedarach, Agastache rugosa, Catalpa ovata, Prunus persica, Sinomenium acutum, Pulsatilla koreana, Oldenlandia diffusa, Anthriscus sylvestris, Schizandra chinensis, Gleditsia sinensis, and Cridium officinale. We also reported the radio-protective effect of DTT. The treatment of DTT increased cell survival after ...

U. K. continental shelf due 800 miles of pipeline in 1993

Compounds isolated from Magnolia officinalis such as magnolol, honokiol and obovatol exhibit several pharmacological effects on CNS including depressant, anxiolytic and anticonvulsant effects, as well as neuroprotective effects against chemical and heat damages. Recently, honokiol was found to have a neurotrophic effect in fetal rat cortical neurons. In the present study, we show that 4-O-methylhonokiol, a novel compound from Magnolia officinalis, promotes neurite outgrowth in a concentration- dependent manner in rat embryonic neuronal cells. In parallel with the neurite outgrowth activity, the expression of neurite outgrowth marker proteins is also increased by treatment with 4-O-methylhonokiol. We also found that 4-O-methylhonokiol promotes the release of NGF and BDNF into cell culture medium. In addition, lower concentration of 4-O-methylhonokiol (1 and 2 lM) further enhanced neurite outgrowth and expression of neurite outgrowth marker ...

Effects of irradiation in medicinal and eatable herbs

This paper reports that more than 800 miles of pipeline will come into service on the U.K. continental shelf during 1993, surpassing by 75% the previous record set in 1977. About 3,500 miles of pipeline is in place. Commissioning of the Miller natural gas pipeline and Scottish Area Gas Evacuation (SAGE) network this year and start-up of the Central Area Transmission System (CATS) next year will bring more than 600 miles of pipeline into use during 1993. The projects are part of a recent development boom in the central North Sea. In a review of U.K. offshore pipeline, analyst County Natwest Woodmac reported that projects totaling about 1,250 miles of pipeline have been sanctioned but are not yet operating. Two thirds of this total is gas pipeline, while 60s made up of main lines from shore to platform. County Natwest says that in most cases spur lines will be used to connect new fields with existing infrastructure. The analyst sees 57 development projects likely to ...

An investigation of some Turkish herbal medicines in Salmonella typhimurium and in the COMET assay in human lymphocytes.

For ages, herbs have been used as medicine and food. Nowadays, the interest in phytotherapeutics is increasing as well as the consumer attention. Some biochemical compounds synthesized by plants as alkaloids, phenolics, flavonoids, essential oils, tannins and vitamins, influence the composition of these plant pharmacologicals, which may produce various reactions in the human body. The microbial contamination in these raw plant materials is common, and the radiation processing is one appropriate technique for the reduction of microorganism. In herbs used as food products, the changes in total #beta#-carotene and flavonoids upon the radiation treatment were tested. The powdered and dehydrated herbs were irradiated with "6"0Co gamma rays applying doses of 0, 10, 20 and 30 kGy. The botanical species investigated were rosemary (Rosmarinus officinalis Linne), watercress (Nasturtium officinale R. Br), artichoke (Cynara scolymus Linne) and sweet basil (Ocimum basilicum ...

Medicinal plants play a major role in the life of Turkish people and of late medicinal plant usage has increased in many countries. Green plants in general contain mutagenic and carcinogenic substances, but there is little information about the biological activities of herbal medicine. In the present study, therefore, various Turkish medicinal herbs were investigated for their genotoxic potential in the Salmonella typhimurium microsomal activation assay and the alkaline single cell gel electrophoresis (COMET) assay. Extracts from these medicinal herbs and some fractions of these extracts were examined. The species investigated were Arctium minus, Ecballium elatterium, Momordica charantia, Plantago major, Urtica dioica, Viscum album, Salvia triloba, Euphorbia rigida, Stachys lavandulifolia, Acteoside, Abies nordmannia. They are used for various immune disorders and are applied either topically or taken orally as a herbal tea. Of the 19 samples of the extracts and ...

Ozone Layer Observations

Drying of medicinal plants with solar energy. Trocknung von Arzneipflanzen mit Solarenergie

The US National Aeronautics and Space Administration (NASA) has been monitoring the ozone layer from space using optical remote sensing techniques since 1970. With concern over catalytic destruction of ozone (mid-1970s) and the development of the Antarctic ozone hole (mid-1980s), long term ozone monitoring has become the primary focus of NASA's series of ozone measuring instruments. A series of TOMS (Total Ozone Mapping Spectrometer) and SBUV (Solar Backscatter Ultraviolet) instruments has produced a nearly continuous record of global ozone from 1979 to the present. These instruments infer ozone by measuring sunlight backscattered from the atmosphere in the ultraviolet through differential absorption. These measurements have documented a 15 Dobson Unit drop in global average ozone since 1980, and the declines in ozone in the antarctic each October have been far more dramatic. Instruments that measure the ozone vertical distribution, the SBUV and SAGE (Stratospheric ...

Power plants 2009. Lectures

Due to the high investment and operation costs incurred by dryers up to 50% of the proceeds from the cultivation of medicinal plants have to be spent on drying. This study was conducted in order to determine whether these costs can be lowered when solar energy is used. As little is known about the drying behaviour of medicinal plants even today one selected sage and camomile in order to study the influence of temperature, relative humidity, and drying air velocity on drying time and drug quality. Laboratory results were used as a basis for developing a solar hothouse dryer for medicinal plants which uses the whole roof surface as solar collectors with a batch dryer set up within the hothouse. In contrast to dryers of this type used up to now a foil green house with a gable roof was used. Installation of a central heating system helps to avoid bottlenecks, allows drying at night and increases plant flow by a factor of 3. The cost of heating oil, however, adds to the ...
