title: [Studies on chemical constituents of mycelium of fungus Cephalosporium sp. AL031(II)].
abstract: Three compounds were isolated from the mycelium of the fungus Cephalosporium sp. AL031 whose metabolites have been proven to possess antifungal and antibacterial activities. Based on the spectral data and elemental analysis, they were identified as 3-hydroxy-ergosta-7,22-dien-6-one(A), penicillic acid(B), 4-hydroxy-3,6-dimethyl-2-pyrone(C). All of these compounds were obtained from the culture medium of this fungus for the first time.
