title: [Study on the chemical constituents in the fruit of Harrisonia perforata].
abstract: OBJECTIVE
  To study the chemical constituents in the fruit of Harrisonia perforata.
  
  
  METHODS
  The chemical constituents were isolated and purified by means of chromatographic techniques and their structures were elucidated by analysis of spectroscopic data and physicochemical properties.
  
  
  RESULTS
  Eight compounds were isolated and identified as caryolane-1,9beta-diol (1), gallic acid (2), 4-O-ethylgallic acid (3), syringic acid ethyl ester (4), protocatechuic acid (5), stigmasterol (6), beta-daucoster (7), beta-sitosterol (8).
  
  
  CONCLUSIONS
  Compounds 1, 3 - 5 and 7 are isolated from this plant for the first time. Compounds 1, 3 and 4 are isolated from this genus for the first time.
