Abstract

Four known (1, 2, 4, and 5) and two new (3 and 6) steroidal glycosides were isolated from Polygonatum glaberrimum K. Koch (Convallariaceae) rhizomes by fractionation of the total extracted compounds. Their structures were determined as (25R)-spirost-5-en-3β,17α-diol 3-O-[α-L-rhamnopyranosyl-(1→2)]-β-Dglucopyranosyl-(1→4)- β-D-xylopyranoside (3) and 26-O-β-D-glucopyranosyl-(25R)-furost-5-en-3β,17α,22α,26-tetraol-3-O-[2″-OAc-α-L-rhamnopyranosyl-(1→2)]-β-D-xylopyranosyl-(1→3)-β-Dglucopyranoside (6).
