摘要	A further phytochemical investigation on the whole plants of Ypsilandra thibetica yielded three new spirostane glycosides, named ypsilandrosides MO (13). Their structures were established as (3 beta,11a,25R)-3,11-dihydroxyspirost-5-en-12-one 3-{O-a-L-rhanmopyranosyl-(1?4)-O-L-rhanmopyranosyl-(1?4)-O-[a-L-rhanmopyranosyl-(1?2)]-beta-D-glucopyranoside} (1), (3 beta,7 beta,25R)-spirost-5-ene-3,7-diol 3-{O-a-L-rhanmopyranosyl-(1?4)-O-a-L-rhanmopyranosyl-(1?4)-O-[a-L-rhanmopyranosyl-(1?2)]-beta-D-glucopyranoside} (2), and (3 beta,7a,25R)-spirost-5-ene-3,7,17-triol 3-{O-a-L-rhanmopyranosyl-(1?4)-O-a-L-rhanmopyranosyl-(1?4)-O-[a-L-rhanmopyranosyl-(1?2)]-beta-D-glucopyranoside} (3) by means of a combination of MS, 1D- and 2D-NMR spectroscopic methods, and chemical degradation. Among them, compound 3 is the first pennogenin (=(3 beta,25R)-spirost-5-ene-3,17-diol) saponin whose aglycone contains an OH group at C(7). Compounds 13 were evaluated for the inhibition of the growth of five tumor cell lines, but all of them proved to be inactive.
