摘要
考察影响微波法提取牡荆总黄酮的主要因素,用正交实验确定了最优提取工艺,并通过脂质过氧化实验初步探讨了牡荆总黄酮的抗氧化活性。结果表明:微波提取牡荆总黄酮的最优工艺为使用30%乙醇溶液,在温度90℃、固液比1:30的条件下微波辐射12min,提取率达9.338%,并且牡荆黄酮具有较强的抗氧化活性。
The microware extracting processing of total flavones in Vitex negundo L.var.cannabifolia(Sieb.et Zucc.)Hand.-Mazz was studied according to the orthogonal design in this paper,and the antioxidation of flavones was studied by the lipid pcroxidation experiment.The results shows that 1:30 of 30% alcohol to the solid weigh ratio to liquid was used with microware treatment last for 12 min at the temperature of 90 ℃,the extraction rate was as high as 9.338%,and the extraction has strong antioxidant activity.
