Strain SZW01 was isolated from sea sediment collected from Shenzhen in Guangdong province, China, and was later identified as Aspergillus fumigatus by16S rDNA sequence analysis. Various chromatographic processes led to the isolation and purification of three compounds from the fermentation culture of SZW01, including a new compound, 2,6′-dihydroxy-2,4’dimethoxy-8′-methyl-6-methoxy-acyl-ethyl-diphenylmethanone (1), and two known compounds: fumigaclavine C (2) and alternarosin A (3), as characterised by UV, IR, 1 D, 2 D-NMR and MS data. The antioxidant and α-glucosidase inhibitory activities of these compounds were evaluated. The result illustrated that compound 1 exhibited a moderate antioxidant activity and stronger α-glucosidase inhibitory activity than acarbose.
