Abstract:
Object To study the chemical constituents from fruiting bodies of Ganoderma lucidum (Leyss ex Fr.) Karst Methods Individual constituent was isolated and repeatedly purified on silica gel column and structurally elucidated by the NMR spectra and X ray diffraction analysis Results Four compounds were obtained from the alcohol extract and identified as 3? oxo formyl 7?, 12? dihydroxy 4, 4, 14? trimethyl 5? chol 11, 15 dioxo 8 en (E) 24 oic acid (Ⅵ); 3? oxo formyl 7?, 12? dihydroxy 5? lanost 11, 15, 23 trioxo 8 en (E) 26 oic acid (Ⅶ); ergosterol (Ⅷ) and ergosta 7, 22 dien 3? ol (Ⅸ), respectively Conclusion Compound Ⅵ and Ⅶ are new triterpenes
