Two new cycloartane-type glycosides, designated as thalictosides V and
IX, were isolated from the methanolic extract of Thalictri Herba (Tak
atogusa), the dried aerial parts of Thalictrum sp. plants. Their chemi
cal structures have been characterized as 3-O-monodesmoside and the 3,
21-di-O-bisdesmoside of 3 beta,22 xi,30-trihydroxycycloart-24-en-21-oi
c acid, by chemical and spectroscopic evidence.
