title: [A new chromone glycoside from Cassia siamea lam].
abstract: OBJECTIVE
  To study the chemical constituents of the stem of Cassia siamea.
  
  
  METHODS
  The compounds were isolated by chromatography on silica gel, and identified on the basis of spectral analysis.
  
  
  RESULTS
  Five compounds were isolated and identified as: beta-sitosterol (I), sucrose (II), n-octacosanol (III), 2-methyl-5-(2'-hydroxypropyl)-7-hydroxy-chromone-2'-O-beta-D-glucopyranoside (IV) and piceatannol (V).
  
  
  CONCLUSIONS
  Compound IV is a new compound. Compounds II, III and V were obtained from this plant for the first time.
