Five compounds were isolated from the ether-soluble fraction of the spores of Gano- derma lucidum.On the basis of their chemical properties and spectral data(MS,UV,IR,~1H and ^(13)CNMR),they were identified as 3,7,11,12,15,23-hexaoxo-5α-lanosta-8-en-26-oic acid(Ⅰ),gano- deric acid B(Ⅱ),C(Ⅲ),D(Ⅳ)and ganodermanontriol(Ⅴ).Compound Ⅰ is a new natural product, named ganosporeric acid A.Compounds Ⅱ,Ⅲ,Ⅳ and Ⅴ are known compounds and were obtained for the first time from the spores of Ganoderma lucidum.Pharmacological experiments showed that ganosporeric acid A has an activity for lowering the levels GPT in mice with liver injury by CCl_4 and GaNI and exhibits heptoprotective effects. 展开更多

A water soluble, (1 -->6)-branched, (1 -->4) linked D-glucan (LB-B1), [alpha](D)(21) = +174.2 degrees (c 0.87, H2O), was obtained from a hot-water extract of the sporoderm-broken spores of Ganoderma lucidun (Fr.... A water soluble, (1 -->6)-branched, (1 -->4) linked D-glucan (LB-B1), [alpha](D)(21) = +174.2 degrees (c 0.87, H2O), was obtained from a hot-water extract of the sporoderm-broken spores of Ganoderma lucidun (Fr.) Karst by HPSEC, with 0.001 mol/L sodium hydroxide as the eluant, the molecular weight (Mw) of LB-B1 was estimated to be 9.3 x 10(3). From the results of total hydrolysis, methylation analysis, acetolysis and 1D, 2D-NMR experimentation, it was concluded that LB-B1 was composed of repeating units with the following structure: alpha -D-Glc(p)-(1 -->6)-alpha -D-Glc(p)-(1 -->6)-alpha -D-Glc(p) 1 down arrow 6 (-->4)-alpha -D-Glc(p)-(1 -->4)-alpha -D-Glc(p)-(1 -->4)-alpha -D-Glc(p)-(1 -->4)-alpha -D-Glc(p)-(1 -->4-)-alpha -D-Glc(p)-(1 -->)(n) 展开更多
