title: [Chemical Constituents from Leaves of Liquidambar formosana].
abstract: OBJECTIVE
  To study the chemical constituents of the leaves of Liquidambarformosana.
  
  
  METHODS
  The chemical constituents were isolated and purified by column chromatography on silicagel, Sephadex LH-20 and MPLC. Their structures were elucidated on the basis of physicochemical properties and special analysis.
  
  
  RESULTS
  Eight compounds were isolated from the leaves of Liquidambar formosana, whose structures were elucidated as gallic acid (1), p-hydroxy-benzoic acid (2), 3-methoxy-4-hydroxy-benzoic acid (3), 3,5-dihydroxy-4-methoxy-benzoic acid (4) kaempferol (5), 3,4-dihydroxy-benzoic acid (6), 3,4-dihydroxy-5-methoxy-benzoic acid (7) and 3β,23,29-trihydroxy-olean-12-en-28-oic acid-β-D-glucopyranosyl ester (8).
  
  
  CONCLUSIONS
  Compounds 1-8 are isolated from the leaves of Liquidambar formosana for the first time.
