title: [A new triterpene from the fruiting bodies of Ganoderma lucidum].
abstract: OBJECTIVE
  To study the chemical constituents of the fruiting bodies of Ganoderma lucidum.
  
  
  METHODS
  Individual constituents, isolated and repeatedly purified on silica gel column, were identified by physicochemical constants and structurally elucidated by spectral methods.
  
  
  RESULTS
  From the alcohol extract, compound 2 was obtained and identified as 3 beta,7 beta-dihydroxy-4,4,14 alpha-trimethyl-11,15-dioxo-5 alpha-chol-8-en-24-oic acid. In addition, two known compounds, lucidenic acid A (1) and C (3) were obtained.
  
  
  CONCLUSIONS
  Compound 2 is a new triterpene compound.
