Methanol extracts from the leaves and stems of Euphorbia microphylla Linn milii were investigated for their activity against Fasciola gigantica, Taenia solium Pheritima pasthuma, respectively. Five concentrations (10–100mg/ml) each extract studied in bioassay, which involved determination time paralysis death worms. All exhibited con-siderable anthelmintic activities, order sensitivity to worms...
DOR: 98.1000/2383-1251.1397.5.71.9.1.1575.1605 Extended abstract Introduction: Generally speaking, plants contain various organic compounds which could influence the behavior of plant communities. These compounds are basically secondary metabolites which are found in various parts of plants such as rhizomes, roots, stems, leaves, flowers, fruits and seeds. The objective of the present st...
In this study, the branch, leaves, flowers, roots and mixed all parts of different nine Euphorbia species were analyzed for their trace element contents by using ICP-MS. The samples were digested by concentrated nitric acid and hydrogen peroxide in a microwave by ICP-MS before the analysis. The accuracy and precision of the method was evaluated by CRM 1573a Tomato Leaves. Trace element contents...
مقدمه: استفاده از گیاهان جهت سنتز نانوذرات به دلیل عدم استفاده از مواد آلاینده و سمی یکی از روش‌های دوست‌دار محیط زیست به شمار می‌رود. هدف: از انجام این مطالعه، سنتز سبز نانوذرات نقره با استفاده از عصاره گیاه Artemisia turcomanica و ارزیابی سمیت نانوذرات نقره سنتز شده بر روی رده سلولی سرطان معده (AGS) می‌باشد. روش بررسی: جهت سنتز نانوذرات نقره زیستی، از عصاره برگ گیاه Artemisia turcomanica استف...
The synthesis of a series of euphorbioside derivatives is described, starting from euphorbioside isolated from fresh latex of Euphorbia resinifera Berg. Their structures have been established on the basis of spectral data. All compounds were evaluated for antibacterial activities against Escherichia coli and Staphyloccus aureus strains and antifungal activity against Candida albicans and Asperg...
Lawrence et al (4) identified the red pigment in bracts of poinsettia as an anthocyanin. The methods employed served to identify the principal anthocyanidin (cyanidin), but not the sugar moiety. Blank (2), Robinson and Robinson (5, 6, 7), and Scott-'Moncrieff (8) reported that variation in the sugar moiety of the anthocyanin pigment affected color. They found that monoglycosides were redder tha...
