Abstract
A new quinochalcone C-glycoside featuring a unique quinonoid moiety, named celochalcoside (1), was isolated from the n-butanol extract of the aerial parts of Celosia trigyna L. The structure was determined by extensive spectroscopic analysis as well as mass spectrometric data. Compound 1 showed moderate cytotoxic activities against breast cancer cell lines (MCF-7), colon cancer cell lines (HT-29) and hepatocellular carcinoma cell lines (HepG2) with IC50 values of 23.16, 37.05 and 18.35 μg/ml, respectively.
