| 摘 要： | 目的:筛选龙胆药材中龙胆苦苷的提取工艺。方法:以龙胆苦苷为指标,利用正交试验法进行提取工艺优选,并以薄层扫描法测定龙胆苦苷的含量。结果:乙醇用量及提取次数对龙胆苦苷的提取有显著性影响(P<0.05)。结论:最佳提取工艺为60%乙醇回流提取3次,每次2h,乙醇用量为药材的18倍。

| Abstract: | OBJECTIVE:To optimize the extraction craft of gentiopicrin from gentian.METHODS:The extraction craft was optimized by orthogonal test with gentiopicrin as an index,and the content of gentiopicroside was determined by TLC scanning method.RESTLUTS:The quantity of menstruum and the extraction times of gentiopicrin had significant influence in the gentiopicrin extraction(P<0.05).CONCLUSION:The best extraction craft is as follows,reflux extraction of60%ethanol for3times and2hour for each time,and the amount of ethanol used was18times that of gentian. |
