title: [Study on the chemical constituents of Clerodendron philippinum var. simplex].
abstract: OBJECTIVE
  To study the chemical constituents of Clerodendron philippinum var. simplex.
  
  
  METHODS
  The ethanol extract of Clerodendron philippinum var. simplex was isolated and purified by extraction, chromatography on silica gel and recrystallization. The structures of compounds isolated were identified by physicochemical properties and spectral analysis.
  
  
  RESULTS
  Four compounds were isolated and identified as friedelin (1), 25 (27)-dehydroporiferasterol (2), 22-dehydroclerosteryl acetate (3), uncinatone (4).
  
  
  CONCLUSIONS
  Compound 2, 3 are isolated form this genus for the first time, Compounds 4 is isolated from this plant for the first time.
