摘要
目的:优选锁阳中总黄酮提取工艺。方法:以乙醇浓度、超声时间、提取温度、固液比为考察因素,以新疆锁阳中总黄酮的含量为评价指标,采用正交试验设计优选最佳提取工艺。结果:最佳提取工艺为80%的乙醇,固液比1∶30,40℃超声提取50min,野生锁阳中总黄酮含量为10.05%。结论:该提取工艺简便、快捷,适用于锁阳中总黄酮的提取。
OBJECTIVE：To optimize the extraction technology of total flavonoids of Cynomorium songaricum.METHODS：The extraction technology of total flavonoids of C.songaricum was optimized by orthogonal experiment using ethanol concentration,ultrasonic extract time,temperature,the liquid-solid ratio as factors and the content of total flavonoids as index.RESULTS：The best extraction conditions was as follows：80% ethanol,liquid-solid ratio of 1：30,40 ℃ ultrasonic extraction for 50 min.The content of total flavonoids of C.songaricum was 10.05%.CONCLUSION：The extraction method is simple,convenient,rapid and applicable for the extraction of total flavonoids from C.songaricum.
