Constituents of Fruit Bodies of Tramete orientalis

A known sterol, 5α,6α-epoxy-5α-crgosta-8(14),22E-diene-3β,7α-diol (1), and two new sterols, 5α,6α-epoxy-3β,8β,14α-trihydroxy-5α-ergost-22E-en-7-one (2), (3α,5α),(8β,11β)-diepidioxy-ergost-22E-en-12-one (3), were isolated and characterized from dried fruit bodies of Trametes orientalis. Their structures were elucidated according to spectral methods.
