Abstract
A new furostanol saponin, named hypoglaucin F, was isolated from the r hizomes of Dioscorea collettii var. hypoglauca, along with seven known compounds. On the basis of detailed chemical and spectroscopic eviden ce, the structure of hypoglaucin F was determined as (25S)-26-O-beta-D -glucopyranosyl 22-hydroxy-5-en-furostane-3 beta, 26, 27-triol L-rhamn opyranosyl-(1-->4)]-beta-D-glucopyranoside.
