Abstract
Two ergosterins and two triterpenoids were isolated from the dried fruit bodies of Ascomyce Bulgaria inquinans. By means of chemical (hydrolysis) and spectroscopic methods (NMR, El-MS), their structures were established as betuinic acid (1), cerevisterol (2), (24R)ergosta-7, 22E-diene-3beta, 5alpha, 6beta-triol-3-O-palmitate (3) and ursolic acid (4). Compound 3 is a new compound.
