In order to discover the novel and bioactive secondary metabolites, the soft coral-associated (Sinularia sp.) symbiotic and epiphytic fungi Aspergillus sp. EGF7-0-1 was fermented by using rice medium. The metabolites were isolated by the chromatography technology and high performance liquid chromatography (HPLC). Ten phenolic acids compounds were obtained. According to the 1D and 2D nuclear magnetic resonance (NMR), high resolution electrospray ionization mass spectroscopy (HR-ESI-MS), optical rotatory dispersion (ORD), and comparison with the literature, their structures were determined as 4-hydroxy-3-(3'-methyl-2'-butenyl) phenylacetic acid (1), asperulosin C (2), 4-hydroxyphenylacetic acid (3), methyl 4-hydroxyphenylacetate (4), 4-hydroxy-3-prenyl-benzoic acid (5), 4-hydroxy-3-(3-methylbut-2-enyl) benzaldehyde (6), p-Hydroxybenzaldehyde (7), methyl 4-hydroxybenzoate (8), 3-hydroxyphenylacetic acid (9) and 2,2'-oxybis(1,4)-ditert-butylbenzene (10). Among them, compound 1 was a new natural product. Antitumor activity studies showed that compounds 1~10 were not active against HCT116, MCF7, Huh 7, Hepa 1-6, 4T1, B16 and F10 tumor cells.
