摘要
目的:筛选毛冬青根中总黄酮提取的最佳条件。方法:采用正交试验研究不同乙醇浓度、提取时间、提取温度和乙醇倍量对总黄酮提取率的影响,采用紫外分光光度法测定总黄酮含量,并以此筛选毛冬青中总黄酮提取的最佳条件。结果:最佳提取条件为:用15倍量的75%乙醇在100℃摄氏度条件下提取1.5h。结论:乙醇浓度影响最大,其次为提取时间,提取温度、乙醇倍量对毛冬青总黄酮提取率影响不明显。
Objective:To opatimize and establish the estraction of total flavones in Pubescent Holly root.Method:The orthogonal design was used test the reflux extraction effect of sovient volume,extraction time,temperature and the ethanol concentration on extacts yield.The content of the total flavones was determined by UV.Result:The optimal extraction condition of the total flabones in Pubescent Holly root,was extracting with 15 times volume of sample weight with 75% ethanol for 1.5h with the temperature of 100℃.Conclusion:The first important effecting is the concentration of ethanol,the second was extraction time.The last is the volume and temperature.
