橄榄根黄酮提取及生物活性测定

Study on of Extracting Total Flavone and Antioxidant Activity from Canarium Album(Lour.)Raeusch

采用乙醇浸提法对橄榄根中黄酮进行提取,并测定其生物活性。探究浓度,料液比,提取时间和温度对黄酮提取的影响,并用正交法进行优化。结果表明,最佳提取参数是乙醇浓度为50%,温度60℃,时间90 min,料液比1∶20(g∶m L)。在此条件下提取黄酮含量为61.92 mg/g,且橄榄根提取物对羟基自由基有一定的清除能力。

This paper aims to extract total quantity flavone from Canarium album （Lour.） Raeusch and to study resistance to oxidation. This research discussed the method of extracting total quantity of flavone and the effect of concentration of menstruum, temperature, time ,ratio of material to liquid. Meanwhile, the best conditions for extraction were chosen after complete rthogonal analysis. The best parametersare 50%ethanol as extractant , temperature on 60℃, extraction time by 90 min, ratio of materialto liquid on 1∶20. In this case, the yield of extraction can reach up to 61.92 mg/g,The Solanum photeinocarpum have the strong antioxidative effect.
