New Steroidal Saponins from the Leaves of Yucca elephantipes

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 (3β,25S)‐spirost‐5‐en‐3‐yl O‐β‐D‐glucopyranosyl‐(1→3)‐O‐β‐D‐glucopyranosyl‐(1→4)‐β‐D‐galactopyranoside (1) and (3β,5β,25R)‐3‐[(2‐O‐β‐D‐glucopyranosyl‐β‐D‐galactopyranosyl)oxy]spirostan‐12‐one (2) on the basis of detailed spectroscopic analysis and acidic hydrolysis.
