chemodiversity in plants provides sources of great value which might be helpful for finding new leads in drug discovery programs. fabaceae as the third largest family of flowering plants was chosen to investigate its possible antifungal activity. in order to increase the effectiveness of the result, molecular similarity methods and chemical data were used. twelve plants were selected from fabac...

kolah ghazi national park is one of the most important habitats for wild goat in iran with a population of around 2000 heads. in order to model the habitat for this species, a presence only layer was used as input to enfa method in biomapper software. ecogeographic factors were also used as independent variables including plant community, distribution of predators, geomorphologic features, main...

PREMISE OF THE STUDY We designed and tested microsatellite markers for the North American native species Silene stellata (Caryophyllaceae) to investigate its population genetic structure and identify selection on floral design through male reproductive success. METHODS AND RESULTS A total of 153 candidate microsatellite loci were isolated based on next-generation sequencing. We identified 18 ...

Three steroids, namely 24-ethyl-5α-cholestan-3-one (1), 5α-stigmast-22-en-3-one (2), stigmast-5, 22-dien-3-one (3) have been isolated from N. stellata. The phytochemical and antimicrobial as well as cytotoxic activities of Nymphaea stellata were investigated in this study. Crude extracts of N. stellata and various column fractions exhibited poor antimicrobial activity against a wide range of Gr...
