英文摘要: Two new spirostanol saponins, namely elephanosides G and H (1 and 2, resp.) were isolated from the leaves of Yucca elephantipes (Agavaceae), together with the two known furostanol saponins 3 and 4 and the six known flavonoid O- and C-glycosides 5-10. The new structures were elucidated as (3,25S)-spirost-5-en-3-yl O--D-glucopyranosyl-(13)-O--D-glucopyranosyl-(14)--D-galactopyranoside (1) and (3,5,25R)-3-[(2-O--D-glucopyranosyl--D-galactopyranosyl)oxy]spirostan-12-one (2) on the basis of detailed spectroscopic analysis and acidic hydrolysis.
