Two New Steroidal Saponins from the Tuberss of Liriope spicata

Two novel steroidal saponins designated as spicatosides A(1) and B(2) were isolated from the tubers of Liriope spicata and their structures were elucidated as 25(S)-rus-cogenin -1-0- fJ - D-glucopyranosyl (1$\rightarrow$2)- [$\beta$ - D-xylopyranosyl (1$\rightarrow$3)] -$\beta$- D- fucopyranoside (1) and 26-0-$\beta$-D-glucopyranosyI25(S)-22-0-methyl-furost-5-en-l$\beta$, 3$\beta$, 26-trioll-0-fJ -D¬glucopyranosyl (1$\rightarrow$2)- [$\beta$- D-xylopyranosyl (1$\rightarrow$3)] - $\beta$- D- fucopyranoside (2), respectively.
