Fresh leaves of C. asiaticum were air dried in shade and pow- dered. The extraction was carried out by mixing the powdered (800 g) leaves with 1:2 (w/v) in 70% ethanol (v/v) for 2 days. The resulted extract was filtered and concentrated by rotary evaporator under reduced pressure and low temperature. The yield of extract was 15% (w/w) in terms of dried starting material.
