Abstract
Aim:
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.
Conclusion:
Compound 2 is a new triterpene compound.
