Abstract
Biological activities of solvent fractions obtained from Cnsicum annuum leaves, being used in material of functional food, were examined by the methods of DPPH scavenging activity, reducing power, nitrite scavenging activity, antimicrobial activity and inhibitory effect on tyrosinase activity. The highest yield was obtained from water fraction, where as the lowest yield was obtained from ethyl acetate traction, 16.9% and 0.6%, respectively. Hydrogen donating activity of Capsicum annuum leaves in increased with increasing amount of extract. Reducing power of the ethyl acetate fraction is increased as the amount of extract is increased. Even in the presence of 900 $\mu\textrm{g}$ of ethyl acetate fraction, reducing power was significantly higher than it was fer the control in which there was no extract. Among the various solvent fractions, ethyl acetate fraction showed the strongest scavenging effect on hydrogen peroxide. Nitrite scavenging effects of all concentrations diminished at higher pH, while in the case of pH 1.2, it showed a nitrite scavenging effect of more than 90% at concentration above of ethyl acetate fraction 500 $\mu\textrm{g}$. Among the various solvent fractions from methanol extract of Capsicum annuum leaves, ethyl acetate and butanol fraction showed the strongest antimicrobial activity. Antimicrobial activity of ethyl acetate fraction was 20 mm against Bacillus cereus, 18 mm against Staphylococcus aureus and 17 mm against Streptococcus mutans. Ethyl acetate fraction showed the strongest of inhibitory activity of tyrosinase.
