Metabolites from the endophytic fungus of Ceriops tagal
To study the chemical constituents from the broth of endophytic fungus Penicillium sp.FJ-1 of Ceriops tagal,the constituents were isolated and purified by column chromatography,and their chemical structures were identified by physicochemical and spectral data.During our investigation on FJ-1,five compounds were isolated.Their structures were identified as 24R-ergosta-7,22-diene-3,5,6-triol (1),altenuene (2),5-hydroxyaltenuene(3),5'-epialtenuene (4),and talaroflavone (5)by their physico-chemical properties and spectral data.All compounds bave been isolated from this endophytic fungus for the first time,and the 1H and 13C-NMR spectral data of compound 3 was first reported.
