title: [Studies on the chemical constituents from the leaf of Liquidambar formosana Hance].
abstract: OBJECTIVE
  To study the chemical constituents from the methanolic extract from the leaf of Liquidambar formosana Hance.
  
  
  METHODS
  The compounds were separated with the column chromatographic and Prep HPLC, and their structures were identified by chemical and spectroscopic methods.
  
  
  RESULTS
  Three compounds were isolated from the methanolic extract. They were identified as: beta-sitosterol (I), alpha-amyrin (II) and oleanonic acid (III).
  
  
  CONCLUSIONS
  All of them were isolated from this plant for the first time.
