title: [Studies on triterpenoid saponins in Hemsleya chensnsis].
abstract: OBJECTIVE
  To study the triterpenoid saponins in Hemsleya chensnsis.
  
  
  METHODS
  The chemical constituents were isolated and purified by various chromatographic methods and their structures were elucidated on the basis of spectral analysis.
  
  
  RESULTS
  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).
  
  
  CONCLUSIONS
  Compounds 1-7 were isolated from this plant for the first time.
