Abstract
Centella asiatica (L) urban, synonym Hydrocotyle asiatica, is found almost all over the world. This plant is famous in Ayurvedic medicine and used in the management of central nervous system, skin and gastrointestinal disorder. Thus this research had been done to evaluate the effect of solvent extraction (Ethanol, Chloroform and Hexane) of C. asiatica on chemical profile, antioxidant activity and antibacterial activity against some foodborne pathogens. The result showed that all solvents (ethanol, chloroform and hexane) used in extraction showed antibacterial activity against Salmonella enterica Typhimurium U302, S. enterica Enteritidis, S. enterica 4,5,12:I human (US clone), Bacillus cereus and B. subtilis at 50mg/ml concentration. In antioxidant part, ethanolic extract gave highest phenolic content and FRAP value. The results also showed that different extraction solvent gave different chemical profile. Hexane extract C. asiatica showed lowest in both antibacterial and antioxidant activity. Ethanolic and chloroform extract of C. asiatica showed promising potential in both antibacterial and antioxidant activity.
