title: [Studies on chemical constituents from rhizome of Impatiens pritzellii var. hupehensis].
abstract: OBJECTIVE
  To study the chemical constituents from the rhizome of Impatiens pritzellii var. hupehensis.
  
  
  METHODS
  The rhizome were extracted with methanol, isolated and purified by column chromatography on silica gel. All the compounds were identified on the basis of spectral analysis (including IR, MS, NMR) and physico-chemical characters.
  
  
  RESULTS
  Five compounds were identified as a-spinasterol (I), alpha-spinasteryl-7, 22-dien-3-O-beta-D-glucopyranoside (II), stigmast-7, 22-dien-3-one (III), stearic acid (IV), hentriantane (V).
  
  
  CONCLUSIONS
  Compound I is isolated from this plant for the first time, Compound II, III, IV, V are isolated from genus Balsaminaceae for the first time.
