Title: Antioxidant Properties of Laoying Tea (Litsea Coreana L.) Extracts
Abstract: The petroleum ether, acetic ester, methanol and water extracts of laoying tea were prepared and their antioxidant properties were studied. At 160 µg/mL, the methanol extract showed a high reducing power of 1.206. With regard to the scavenging ability on 1,1-diphenyl-2-picrylhydrazyl radicals, extracts were effective in the order: methanol > acetic ester > water > petroleum ether extracts. EC 50 values for chelating ability on ferrous ions for petroleum ether, acetic ester, methanol and water extracts were 11.76, 14.32, 6.05 and 1.02 mg/mL, respectively. Based on EC 50 values, the various extracts from laoying tea were effective antioxidants.
