茶多酚%类胡萝卜素:协同抗氧化作用
茶多酚%類鬍蘿蔔素:協同抗氧化作用
다다분%류호라복소:협동항양화작용
tea polyphenol%caroteniods%synergistic antioxidative activity
采用DPPH和羟自由基(·OH)体系的清除试验,比较茶多酚与类胡萝卜素单独和复配后的抗氧化活性.结果显示:在羟自由基(·OH)体系中两者的协同抗氧化能力更为显著,当茶多酚浓度稀释一倍或两倍时,随类胡萝卜素浓度的升高,两者的混合物对羟自由基(·OH)的清除率也逐渐升高.在DPPH自由基体系中,当茶多酚浓度稀释一倍或两倍时,随类胡萝卜素浓度的升高,两者的混合物对DPPH自由基的清除率先升高后降低.
採用DPPH和羥自由基(·OH)體繫的清除試驗,比較茶多酚與類鬍蘿蔔素單獨和複配後的抗氧化活性.結果顯示:在羥自由基(·OH)體繫中兩者的協同抗氧化能力更為顯著,噹茶多酚濃度稀釋一倍或兩倍時,隨類鬍蘿蔔素濃度的升高,兩者的混閤物對羥自由基(·OH)的清除率也逐漸升高.在DPPH自由基體繫中,噹茶多酚濃度稀釋一倍或兩倍時,隨類鬍蘿蔔素濃度的升高,兩者的混閤物對DPPH自由基的清除率先升高後降低.

Use scavenging experiment of the system that were made up of DPPH radical and hydroxyl radical (·OH) to compare the antioxidant activity among the individual polyphenols and carotenoids and the compound of them.The result showed that:in the system of hydroxyl radical (·OH),the synergistic antioxidant capacity of both of them is more significant.When the concentration of polyphenols diluted double or triple and with the carotenoid concentration increasing,then the mixture of both hydroxyl radical (·OH) clearance rate also increased.In DPPH radical system,when the concentration of polyphenols diluted double or triples and with the carotenoid concentration increasing,then the mixture of both DPPH radical clearance rate raised first and educed later.
