title: [Chemical constituents from the leaves of Cassia angustifolia].
abstract: OBJECTIVE
  To study the chemical constituents from the leaves of Cassia angustifolia.
  
  
  METHODS
  Compounds were isolated and repeatedly purified by chromatographic techniques on silica gel column. Their structures were elucidated by chemical and spectral methods.
  
  
  RESULTS
  eight compounds were isolated from the leaves of Cassia angustifolia, and identified as tinnevellin glycoside(I), isorhamnetin-3-O-beta-gentiobioside(II), apigenin-6,8-di-C-glycoside(III), emodin-8-O-beta-D-glucopyranoside(IV), kaempferol(V), aloe emodin(VI), D-3-O-methylinositol(VII), sucrose(VIII).
  
  
  CONCLUSIONS
  Compounds III, VII and VIII are isolated from the plant for the first time.
