ANTIMICROBIAL AND ANTIFUNGAL ACTIVITIES OF 3 NEW TRITERPENOID GLYCOSIDES

The antimicrobial and antifungal activities of the MeOH extract of the flowers of Cephalaria transsylvanica and three triterpenic acid glyco sides, transsylvanoside A-C from the flowers of the plant were assayed using an agar-disc diffusion method. The results showed that both the MeOH extract and the glycosides possess antimicrobial and antifungal activities against Staphylococcus aureus, Escherichia coli, Proteus vu lgaris, Pseudomonas aeruginosa Corynebacterium xerosis, Klebsiella pne umoniae, Candida utilis, Kluyveromyces fragilis, Aspergillus oryzae an d Aspergillus flavus respectively.
