title: Triterpenoid saponins and monoterpenoid glycosides from Incarvillea delavayi.
abstract: Two new triterpenoid saponins, incarvillosides A (1) and B (2), and two new monoterpenoid glycosides, incarvillosides C (3) and D (4), were isolated from the high-polarity fraction of the whole plant of Incarvillea delavayi. By means of spectroscopic data and chemical degradation, the structures were established as (3beta,21beta)-3,19,21,23-tetrahydroxyurs-12-en-28-oic acid 28-O-beta-d-glucopyranoside (1), (2beta,3beta,19alpha)-2,3,19,23-tetrahydroxyolean-12-en-28-oic acid 28-O-beta-d-glucopyranoside (2), (2S,6R)-2,6-dimethyl-1,8-octanediol 1-O-beta-d-glucopyranoside (3), and (2S,6R)-2,6-dimethyl-1,8-octanediol 8-O-beta-d-glucopyranoside (4).
