-
Abstract
Four compounds were isolated from CH2Cl2 soluble fraction of the fruiting body of Ganoderma lucidum.On the basis of their spectral data( MS,UV,IR,1HNMR,13CNMR and2DNMR)they were identified as 7β-hydroxy-3,11 ,15-trioxo-lanosta-8-en 24→20 lactone(Ⅰ),5α-lancota-7,9(11), dien-3β,24 ,25,26 tetrol(Ⅱ), 5α-lanosta-7,9(11),24-trien-3β.26-diol(Ⅲ)and 5α-lancota7,9(11),24-trien-3β,26,27-triol.Compound I is a new compound namedganolactone.
