Four new fatty acid derivatives from sp. T24, an endophytic fungus isolated from .

The endophytic fungus sp. is known to contain many secondary metabolites, but fatty acid derivatives have rarely been found. In this study, four new fatty acid derivatives (-), together with four known compounds (-), were isolated from sp., which was obtained from the stem of . The absolute configurations of the new compounds - were deduced based on spectroscopic technique and -based coupling constant analysis. Moreover, compound exhibited cytotoxic activities against HCT-8 and MCF-7 cancer cells, and compounds and showed modest selectivity for HCT-8 cells by MTT assay.
