title: [Study on triterpenes from Solanum torvum].
abstract: OBJECTIVE
  To study on the chemical constituents of Solanum torvum.
  
  
  METHODS
  The aerial parts of S. torvum swartz were extracted with 95% alcohol and the constituents were isolated and purified by chromatographic silica gel and Sephadex LH-20. Their structures were determined by NMR and MS spectral analysis.
  
  
  RESULTS
  Six triterpenes were isolated and identified as 3beta-acetyloleanolic acid (1), 3-O-acetyl-11alpha, 12alpha-epoxy-oleanan-28, 13beta-olide (2), oleanolic acid (3), ursolic acid (4), 2alpha-hydroxy-oleanolic acid (5), 2alpha, 3beta-dihydroxyursolic acid (6).
  
  
  CONCLUSIONS
  All compounds were obtained from this plant for the first time.
