Chemical constituents from fruiting bodies of Ganoderma tsugae (Ⅱ) / 中草药

ABSTRACT

Objective To study the chemical constituents from the fruiting bodies of Ganoderma tsugae. Methods To isolate the compounds by silica gel and Sephadex LH-20 column chromatography and to elucidate their structures by means of spectral analyses. Results Eight triterpenoids were obtained from EtOAc fraction of EtOH extract and identified as ganoderiol A (Ⅰ), ganodermanontriol (Ⅱ), ganodermatriol (Ⅲ), ganoderic acid C (Ⅳ), ganoderic acid A (Ⅴ), lucidone A (Ⅵ), lucidenic acid C (Ⅶ), and lucidenic acid LM1 (Ⅷ). Conclusion Compounds Ⅰ-Ⅷ are all isolated from G. tsugae for the first time.
