Chemical constituents of Aglaia loheri

The dichloromethane extract of the leaves of Aglaia loheri afforded spinasterol (1), trilinolein (2) and phytyl fatty acid ester (3). The structures of 1-2 were identified by comparison of their 13C NMR data with those reported in the literature. Compounds 1, 2 and 3 were evaluated for cytotoxicity against the colon carcinoma (HCT 116) using the MTT assay. They exhibited moderate cytotoxicity against HCT 116 with IC50 values of 40.52, 46.73 and 40.06, respectively.
