Objective:
To study the triterpenoid saponins in Hemsleya chensnsis.
Method:
The chemical constituents were isolated and purified by various chromatographic methods and their structures were elucidated on the basis of spectral analysis.
Result:
Seven 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).
Conclusion:
Compounds 1-7 were isolated from this plant for the first time.
