Abstract:
Ten compounds were isolated from cultures of the fungus Armillaria mellea by silica gel and Sephadex LH-20 column chromatographies. Their structures were identified by spectroscopic data analysis and compared their spectroscopic data with those reported in the literature as 2-hydroxy-4-methoxy-6-methylbenzoic acid (1), orsellinic acid (2), melleolide (3), ergosterol (4), genistein (5), daidzein (6), daucosterol (7), genistin (8), uracil (9) and D-mannitol (10). Compounds 1-10 were isolated from cultures of A. mellea for the first time. Among them, 14, 6 and 10 had been obtained from mycelia or rhizomorphs of A. mellea. The structure of compound 3 was determined by detailed analysis of its 1D and 2D NMR data in the solvent of DMSO for the first time.
