Abstract
The nitrite-scavenging and antimutagenic effects of various solvent extracts from different parts of the loquat. were investigated to develope as source of functional food. The nitrite-scavenging and antimutagenic effects of fractions obtained from methanol extract were most highest in ethyl acetate fraction. Ethyl acetate fraction showed better results in the nitrite scavenging activity of 80% in leaf, 81% in seedless fruit, 73% in peel and 63% in seed. The antimutagenic effect showed strong ethyl acetate fraction of 53.1%, 48.3% in leaf and seedless fruit. The antimutagenic effect increased with increasing concentration of ethyl acetate fraction against mutagenicity induced by direct mutagen of IQ in Salmonella typhimurium TA 100. Addition of 2.5 mg and 5 mg of ethyl acetate fraction showed inhibitory effect of 65.5%, 71.2% in leaf and 63.4%, 69.2% in seedless fruit, respectively.
