Abstract
The Isolation and Purification of ethyl acetate fraction from Muntingia calabura leaves have resulted three flavonoid derivatives. UV-Vis, 1H-NMR dan 13C-NMR data showed that isolate compounds are 2,4-dihydroxychalcone (1), 3,7-dimetoxy-5-hydroxyflavon (2) and 3,5,7-trihydroxy-8-methoxyflavone (3). The antioxidant evaluation against 2,2-diphenyl-1-picrylhydrazyl (DPPH), compound (3), showed to be a very high activity (IC50 3,7 x109 ppm). The isolated compounds were also evaluated for their cytotoxic activities against murine leukemia P-388 cells resulted that all isolated compounds were inactive.
