摘要

In our screening program for new antifungal agents from microbial secondary metabolites,two new isoflavonol glycosides with potent antifungal activity,talosins A and B,were isolated from the culture broth of Kitasatospora kifunensis MJM341.Talosins A and B were determined to be genistein 7-alpha-L-6-deoxy-talopyranoside and genistein 4',7-di-alpha-L-6-deoxy-talopyranoside,respectively,by spectroscopic studies.They are the first flavonoid glycosides incorporating 6-deoxy-talose as a sugar component.
