A new steroidal saponin from the rhizomes of Costus spicatus

A new steroidal saponin has been isolated from the rhizomes of Costus spicatus and its structure was elucidated as (3 beta, 22 alpha, 25R) -26-(beta-D-glucopyranosyloxy)-2-methoxyfurost-5-en-3-yl O-D-apio-beta-D-furanosyl-(1-->4)-O-[alpha-L-rhamnopyranosyl-(1--> 2)]- beta-D-glucopyranoside by...
