[A new triterpene from the fruiting bodies of Ganoderma lucidum].
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.
