【摘要】 以橙皮苷和锌金属盐为原料进行配合反应合成橙皮苷-锌配合物.以产率为指标,通过单因素和正交试验确定了合成橙皮苷-锌配合物的最佳条件为反应温度40℃,pH值10.0,反应时间45min,所得配合物产率达72.50%.同时,通过橙皮苷和橙皮苷锌对DPPH·自由基、羟自由基(·OH)、超氧阴离子(O:-·)三种自由基的对比清除实验,证明了橙皮苷锌配合物清除自由基的能力强于橙皮苷.更多还原

【Abstract】 Using hesperidin and zinc as raw material,hesperidin with zinc omplex is synthesized.Taking yield ratio of hesperidin with zinc complex as target ,by single factor method and orthogo-nal experiment design the best reaction condition:temperature is 40 ℃ ,pH value is 10. 0,the timeis 45 min,the yield can reach 72.50%. Meanwhile,through the contrast tests on the scavengingreaction to DPPH. radical,hydroxyl radical ( . OH),and superoxide free radical (O2-. ) ofhesperidin and hesperidin-with zinc complex,proves that the scavenying capacity of free radicalof hesperidin-with zinc complex is stronger than that of hesperidin.更多还原
