资源简介：
A new limonoid compound 11α-hydroxydisobinin (1), along with a known limonoid compound (2), was isolated from ethyl acetate extract of Chisocheton macrophyllus (Meliaceae) seeds. The structure and stereochemical configuration of compound 1 was characterized by HR-ESI-MS, UV, IR, NMR, and ECD analysis through quantum chemical calculations (TD-DFT analysis and DP4+ NMR). Both limonoids were tested for their cytotoxic activities against MCF-7 breast cancer cells with IC50 values of 112.5 and 51.7 µM.
