    Author: Yaoita Y, Matsuki K, Iijima T, Nakano S, Kakuda R, Machida K, Kikuchi M.
    Journal: Chem Pharm Bull (Tokyo); 2001 May; 49(5):589-94. PubMed ID: 11383612.
    Abstract:
    Four edible mushrooms, Panellus serotinus, Lepista nuda, Tricholoma matsutake and Naematoloma sublateritium, have been investigated chemically. Two new sterols, 5alpha,9alpha-epidioxy-(22E)-ergosta-7,22-diene-3beta,6alpha-diol (1) and 5alpha,9alpha-epidioxy-(22E)-ergosta-7,22-diene-3beta,6beta-diol (2), have been isolated from Panellus serotinus. Compound 2 was also isolated from Lepista nuda. A new sterol, 3beta,5alpha,9alpha,14beta-tetrahydroxy-(22E)-ergosta-7,22-dien-6-one (3), and compound 2 have been isolated from Tricholoma matsutake. Three new triterpenoids, sublateriols A-C (4-6), have been isolated from Naematoloma sublateritium. The structures of the new compounds were elucidated on the basis of their spectral data.
