摘要
以侧柏叶为试验材料,采用超声波法辅助提取黄酮,通过单因素试验考察超声波时间、超声波温度以及超声波频率对黄酮得率的影响。在单因素试验基础上,采用响应面法优化提取工艺,结果表明,超声波法辅助提取侧柏叶中总黄酮的最佳工艺条件为:超声波时间51 min、超声波温度60℃、超声波频率40 kHz,此时黄酮得率为(26.350±0.065)mg/g。
The extraction of favonoids from the leaves of Platycladus orientalis was carried out by ultrasonic assisted method. The effects of ultrasonic time,temperature and frequency on the yield of flavonoids were investigated by single factor test. On the basis of single factor experiment,response surface method was used to optimize the extraction process. The results showed that the optimum conditions of extraction of total flavonoids from the leaves of Platycladus orientalis were ultrasonic time 51 min,ultrasonic temperature 60 ℃,ultrasonic frequency 40 kHz,and the yield of flavonoids was(26.350±0.065)mg/g.
