Variation in transpiration efficiency (TE) and its relationship with the stable carbon isotope ratio of wood was investigated in the saplings of three tropical tree species. Five individuals each of Platymiscium pinnatum (Jacq.) Dugand, Swietenia macrophylla King and Tectona grandis Linn. f. were grown individually in large (760 l) pots over 16 months in the Republic of Panama. Cumulative trans...
BACKGROUND Millettia macrophylla was previously reported to have estrogenic effects and to prevent postmenopausal osteoporosis in Wistar rats. So, the study deals with the identification of its secondary metabolites and the evaluation of their estrogenicity and cytotoxicity toward tumoural cells. Thus, 13 known compounds were obtained from successive chromatographic columns and identified by NM...
سابقه و هدف: مطالعات پیشین نشان دادهاند که عصاره گیاه سنبل الطیب با مداخله در مکانیسم های سیستم گاباارژیک، اثرات آرام بخشی و ضد اضطرابی ایجاد می کنند. با توجه به اینکه سیستم نورآدرنرژیک مرکزی نقش مهمی در رفتارهای اضطرابی دارد، در این پژوهش دخالت این سیستم در اثر ضد اضطرابی عصاره آبی-الکلی ریشه گیاه سنبل الطیب در موش سوری نر بالغ مورد بررسی قرار گرفته است. مواد و روش ها: در پژوهش حاضر از 63...
Systematic bioassay-guided fractionation of the methylene chloride extract of the roots from Ligularia macrophylla was performed to identify both phytotoxic and antifungal compounds. Four phytotoxic eremophilanes (furanoeremophilan-14beta,6alpha-olide, 6beta-angeloyloxy-10beta-hydroxyfuranoeremophilane, eremophil-7(11)-ene-12,8alpha;14beta,6alpha-diolide, and 3alpha-angeloyloxybakkenolide A) an...
The genus Salacia (Celastraceae: Salaciodeae) in peninsular India is revised, wherein ten species are recognised. Eight endemic to the region. macrophylla and S. reticulata excluded from revision as occurrence of both doubtful mainland India. macrosperma exhibits great variation leaf shape, flower number, pedicel length fruit texture, hence morphologically similar beddomei vellaniana relegated ...
Lumusidines A-D, bisindole alkaloids of the macroline-macroline type, and one of the macroline-pleiocarpamine type, villalstonidine F, were isolated from the stem-bark extract of Alstonia macrophylla (Apocynaceae). The structures and absolute configurations of these alkaloids were established using NMR, MS, and X-ray diffraction analyses.
Trivalvaria rubra and Trivalvaria casseabriae, two new species of Annonaceae from Putao, Kachin State, Myanmar, are here described and illustrated. They are morphologically similar to T. costata and T. macrophylla. The major differences between them are outlined and discussed. A diagnostic key to the species of Trivalvaria is provided.
سنبل الطیب (valeriana officinalis l.) به عنوان یک گیاه دارویی ارزشمند همواره مورد توجه و استفاده انسان بوده است. با این حال، به رغم سابقه طولانی از کشت این گیاه همچنان مشکلاتی در زمینه تولید از جمله مدیریت علف های هرز این گیاه دارویی وجود دارد. بنابراین، این تحقیق با هدف ارزیابی اثر علف کش های پس رویشی پهن و نازک برگ کش به صورت انفرادی و مخلوط بر گیاه دارویی سنبل الطیب انجام شد. این پژوهش در قا...
Background:Callicarpa macrophylla (Varbenaceae) is a medicinal shrub and is traditionally used in India, China, and South Asia. Methods: The plant material was collected from lower Himalayan region of Uttarakhand in India. The essential oils from three different aerial parts were analyzed by GC-MS. Antioxidant activity, phenolic assay, and various pharmacological activities were determined by u...
the current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of eremostachys azerbaijanica (labiatae) as well as analyzed the potent extracts using gc-ms. extracts of e. azerbaijanica in n-hexane, dichloromethane (dcm) and methanol (meoh) were prepared using a soxhlet apparatus. the antioxidant activity of the extrac...
