The antimicrobial and antifungal properties of several crude extracts and pure saponins, astraverrucins I-VI, from the aerial parts of Astragalus verrucosus were investigated by the disc diffusion method. Antimycotic activity was observed on more polar extracts, but only one saponin showed an appreciable activity.
