摘　　要：在不同的条件下对龙柏叶总黄酮含量的提取结果表明 :溶剂乙醇的体积分数、提取时间和提取温度对总黄酮提取量都有不同程度的影响 ,其中乙醇的体积分数对总黄酮的提取量影响最为显著。通过正交试验得出龙柏叶总黄酮提取的最佳条件是溶剂乙醇的体积分数为75 %,提取时间为 2 0min ,提取温度为 90～ 1 0 0℃。表 5参The results of extracting flavonoid compounds from dragon juniper leaves under different conditions show that alcohol volume percentage,extracting time and temperature all affect the amount of total flavone that is extracted.One of them alcohol volume percentage is a key factor.The best conditions of extracting flavonoid compounds from dragon juniper leaves are as follows:alcohol volume percentage is 75%,extracting time 20 min,and extracting temperature 90～100 ℃.
