title: [Study on Chemical Constituents of Petroleum Ether Fraction from Rubus alceaefolius].
abstract: OBJECTIVE
  To investigate the chemical constituents of Rubus alceaefolius.
  
  
  METHODS
  Nine compounds were isolated and purified from the petroleum ether extract of 95% alcohol extract of Rubus alceaefolius by repeated column chromatography on silica, Sephadex LH-20 and structurally identified by spectral analysis.
  
  
  RESULTS
  The compounds were identified as chrysophanol(1), physcion (2), β-sitosterol(3), 3-oxotirucalla-7, 24-dien-21-oic acid(4), myricadiol(5), 19-α-hydroxy-3-acetyl-ursolic acid(6), N-benzoylphenylalaninyl-N-benzoylphenylalaninate(7), aurantiamide acetate(8) and euscaphic acid(9).
  
  
  CONCLUSIONS
  Compounds land 4~8 are isolated from this plant for the first time, and compounds 4 - 8 are found in plants of Rubus genus for the first time.
