摘要
目的:研究新疆紫花苜蓿中总黄酮的提取工艺。方法:以总黄酮含量为考察指标,采用正交实验法,考察加醇量、超声提取时间、超声功率、乙醇浓度4个因素对提取工艺的影响。结果:最佳提取工艺为A2B1C1D2,结合生产实际,确定最佳工艺为70%乙醇超声提取20分钟,超声功率为60%,加乙醇量为30倍量。结论:正交实验法优选新疆紫花苜蓿总黄酮的提取工艺简便、快速、准确。
Objective:Study on the extracting flavonoid compounds from Alfalfa of Xinjiang.Methods:With flavonoid content as the inspection indicators,orthogonal test was used to investigate the influence of four extrac-ting factors(ethanol volume,ultrasonic time,ultrasonic power and ethanol consistence)on the extracting process.Results:The optimum extracting process was A2B1C1D2,ie The ethanol volume being 30 times of the weight of medicinal material,extracted for 20 minutes under the power of 60% with ultrasonic extraction,and 70% ethanol consistence.Conclusion:Optimization of extracting process for Alfalfa by orthogonal test is a simple,quick and accuratemethod.
