Abstract

Solakhasoside (1), a novel steroidal saponin, was isolated from the fruit of Solanum khasianum. Its structure was determined as (23S, 25S)-spirot-5-en-3beta,17alpha, 23-triol-3-O-[alpha-L-rhamnopyranosyl-(1-->2)[beta-D-xylopyranosyl-(1 -->3)]-beta-D-galactopyranoside] (1) by spectroscopic analysis.
