title: [Study on triterpenoids from Wisteria sinensis].
abstract: OBJECTIVE
  To study the triterpenoids constituents from Wisteria sinensis Sweet Caulis.
  
  
  METHODS
  The compounds were beta-solated and purified with silica gel and Sephadex LH-20 column chromatography from the petroleum ether extract. Their structures were determined on the basis of physicochemical properties and spectroscopic analysis.
  
  
  RESULTS
  They were identified as beta-sitosterol palmitate (1), alpha-spinasterol (2), (22E, 24R)-5alpha, 8alpha-epidioxy-ergosta-6, 22-dien-3beta-ol (3), (22E, 24R)-ergosta-5, 7, 22-trien-3beta-ol (4), (22E, 24R) -ergosta-7, 22-dien-3beta-ol (5), 11alpha, 12alpha-oxidotaraxerol (6), lupeol (7), betulinic acid (8), 22-oxo-3beta, 24-dihydroxyolean-12-ene (9), 2alpha, 3beta, 23-trihydroxyolean-12-ene (10), soyasapogenol E (11), 3alpha, 21beta-dihydroxy-olean-12-ene (12).
  
  
  CONCLUSIONS
  Compounds 1 - 12 are isolated from this plant for the first time.
