Abstract:
OBJECTIVETo study the triterpenoid saponins in Hemsleya chensnsis.
METHODThe chemical constituents were isolated and purified by various chromatographic methods and their structures were elucidated on the basis of spectral analysis.
RESULTSeven known triterpenoid saponins were isolated from the root of H. chensnsis and were identified as 3-O-beta-D-glucuropyranosyl-oleanol-icacid (1), 3-O-beta-D-glucopyra-noside-oleanolicacid-28-O-beta-D-glucopyranoside (2), 3-O-(6'-methylester)-beta-D-glucuropyranosyl olea- nolic acid-28-O-alpha-L-arabinopyranoside (3), 3-O-(6'-methylester)-beta-D- glucuropyranosyl- oleanolic acid-28-O-beta-D-mannupyranoside (4), 3-O-(6'-ethyl ester)-beta-D-glucuropyranosyl oleanolic acid-28-O-beta-D- glucopyranoside (5), 3-O-alpha-L-arabinopyranoside-(1-->3) -beta-D-glucuropyranosyl- oleanolic acid-28-O-beta-D-glucopyranoside (6), 3-O-beta-D-glucu-ropyranosyl-oleanolic acid-28-O-beta-D-glucopyra-noside-(1-->6)-beta-D-glucopyranoside (7).
CONCLUSIONCompounds 1-7 were isolated from this plant for the first time.
