蕲艾燃烧灰烬提取物抗自由基作用

Anti-Free Redical Activity of QIAI Burning Ashes

通过甲醇萃取艾叶燃烧灰烬获得了4种不同组分,研究了它们对甲基丙烯酸甲酯自由基聚合反应中反应速率的影响,通过反应体系的黏度测定研究了其抗自由基的作用.结果表明:上述4种组分均具有比较强的抗自由基能力.

Four components were obtained from the burnt ashes of Artemisia argyi Levl. et Vant. ca. qiai by methanol extraction and their effects on the rate of free radical polymerization reaction of methyl methylacrylate were studied. The anti-free radical ability of these different components was investigated by measuring the viscosity of the reaction system. The results showed that the above-mentioned components had relatively strong anti-free radical ability.
