%X two new metabolites, ethyl 2,4-dihydroxy-5,6-dimethylbenzoate (1) and phomopsilactone (2) were isolated from phomopsis cassiae, an endophytic fungus in cassia spectabilis. their structures were elucidated by 1d and 2d nmr, ms and ir spectral data. compounds 1 and 2 displayed strong antifungal activity against the phytopatogenic fungi cladosporium cladosporioides and c. sphaerospermum, as well as cytotoxicity against human cervical tumor cell line (hela), in in vitro assays.
