16种中草药提取物的抗氧化活性研究
Study on antioxidant activity of the extracts from 16 kinds of Chinese herbs
摘要
Abstract
Ultrasonic extraction was used to extract 16 kinds of Chinese herbs with ethanol , 50% ethanol solution and water as solvents .The antioxidant capacity of the extracts was measured and evaluated by three kinds of antioxidant activity evaluation methods in vitro . The results showed that the ethanol extracts of Rhodiola rosea L .,Polygonum multif lorum and Herba Cistanche had better scavenging effects to DPPH ・ ,・ OH and ・ O2 - free radicals ;three kinds of extracts of Punica granatum L .had strong scavenging activity to DPPH・and・O2 -free radicals ,the same as the water extracts of Citrus aurantium L .and Salvia miltiorrhiza Bge .;and the water extracts of all herbs exhibited lower scavenging effects to・OH free radicial .关键词
