Abstract

Five new (15) and twelve known (617) different types of glycosides together with a known sesquiterpene triol (18) were isolated from the methanol extract of the rhizomes of Notopterygium incisum. The new structures were elucidated by means of spectroscopic and chemical methods to be pregn-5-en-3β,20(S)-diol-3-O-bis-β-D-glucopyranosyl-(l → 2,1 → 6)-β-D-glucopyranoside (1), oleuropeic aldehyde 8-O-β-D-glucopyranoside (2), 2(R)-(3,4-dimethoxyphenyl)-propane-1,3-diol-1-O-β-D-glucopyranoside (3), eudesman-3α,4α,11-triol-11-O-β-D-glucopyranoside (4), and marmesin-11-O-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranoside (5). The absolute configuration of the aglycone in compound 3 was assigned by application of Klyne's rule.
