title: [Studies on chemical constituent of Solanum lyratum].
abstract: OBJECTIVE
  To study chemical constituents of Solanum lyratum.
  
  
  METHODS
  The constituens were isolated by polystyrene resin RA, sephadex LH-20 and silica gel column chormatography, their structures were identified by spectroscopic analysis.
  
  
  RESULTS
  Four compounds were identified as The constituens were caffeic acid, vanillic acid, rutin and N(p-hydropheneethyl) p-coumaramide.
  
  
  CONCLUSIONS
  These compounds were isolated from this plant for the first time.
