title: (22E)-Ergosta-6,22-diene-3beta,5alpha,8alpha-triol: a new polyhydroxysterol isolated from Lentinus edodes (Shiitake).
abstract: From the ethanolic extract of Lentinus edodes (Shiitake) eight known sterols were isolated and identified: ergosterol, ergosterol peroxide, (22E)-ergosta-5,7,9(11), 22-tetraen-3beta-ol, (22E)-ergosta-7,9(11),22-trien-3beta-ol, (22E)-ergosta-6,8,22-trien-3beta-ol, (22E)-norergosta-5,7,9,22-tetraen-3beta-ol, 3beta,5alpha-dihydroxy-(22E)-ergosta-7,22-dien-6-one, (22E)-ergosta-4,6,8(14),22-tetraen-3-one and, for the first time in mushrooms, (22E)-ergosta-6,22-diene-3beta,5alpha,8alpha-triol.
