Antibacterial constituents from fruit bodies of AscomyceBulgaria inquinans
Two ergosterins and two triterpenoids were isolated from the dried fruit bodies of AscomyceBulgaria inquinans. By means of chemical (hydrolysis) and spectroscopic methods (NMR, EIMS), their structures were established as betuinic acid (1), cerevisterol (2), (24R)ergosta-7, 22E-diene-3β, 5α, 6β-triol-3-O-palmitate (3) and ursolic acid (4). Compound3 is a new compound.
