Steroidal glycosides from the underground parts of Allium ursinum L. and their cytostatic and antimicrobial activity.
The aim of this study was the isolation and structural elucidation of steroidal glycosides from the underground parts of ramson Allium ursinum L. The structures of the isolated compounds were established based upon chromatographic methods and 1D- and 2D-NMR, MS and IR analyses. The mixture of two steroidal saponins: (25R)-spirost-5-en-3b-ol tetrasaccharide and (25R)-spirost-5, 25(27)-dien-3b-ol...

Objective: The methanol extracts obtained from the seeds of Hyoscyamus niger L. (Solanaceae) were investigated for their antimicrobial activities against the pathogens causing complicated urine tract infections. Methods: The seeds of plant were extracted with aqueous 60% methanol. The extract was screened against urinary tract pathogens (Enterococcus faecalis, Escherichia coli, Klebsiella pneum...
متن کاملIn-vitro Antitumor Activity and Antifungal Activity of Pennogenin Steroidal Saponins from paris Polyphylla var. yunnanensis
Paris polyphylla Smith var. yunnanensis, has been used in traditional Chinese medicine for its antibiotic and anti-inflammatory properties; in addition it has been used to cure liver cancer in particular. In this current study, β-ecdysterone (1) and three pennogenin steroidal saponins (2-4) were isolated from the EtOH extract of Paris polyphylla var. yunnanensis, and then tested for their antit...
