Chemistry of Natural Compounds Aims and scope

A new pyranone, 2-methoxy-3,6-diphenyl-4H-pyran-4-one, named betulinan C, together with three known compounds, 5α,8α-epidioxy-22E-ergosta-6,22-dien-3β-ol (2), β-sitosterol (3), and ergosta-7,22-dien-3-one (4), was isolated from the ethanol extract of Lenzites betulina. Their structures were determined by analysis of spectroscopic data. Compounds 3 and 4 were isolated from the macrofungi for the first time.
