| 摘 要： | 本研究采用正交试验分析和分光光度法,建立了块根紫金牛总黄酮含量测定的方法并比较分析其不同产地及不同部位总黄酮的含量差异。结果表明超声波法提取块根紫金牛中总黄酮的最佳提取工艺为：乙醇浓度60%,料液比1：70,提取时间50min,提取功率200W,提取温度70℃。另外,不同产地块根紫金牛中总黄酮含量顺序为：靖西〉那坡〉德保〉扶绥〉龙州〉武鸣;同一产地块根紫金牛根、茎、叶间总黄酮含量的高低顺序大致为：叶〉根〉茎。且通过精密度、重复性、稳定性和回收率实验来检测最佳提取工艺条件,结果显示该方法操作简便,结果准确,重复性好,RSD为0.788%,稳定性和回收率较高,平均回收率达96.20%。证明该方法可用于比较不同产地块根紫金牛药材中总黄酮的含量差异,对不同产地块根紫金牛的药材质量分析具有一定的指导作用。

| Abstract: | In this research, we established a method of quantity determination of total flavonoid in Ardisiacorymbifera Mez var. tuberifera C. Chen and comparative analysed content differences of flavonoid in different sections A. var. tuberifera from different areas by orthogonal experiment and spectrophotometry. The results indicated the optimum extractive technology of determination of total flavonoid in A. var. tuberifera by spectrophotometry was that extraction reagent 60% alcoho1, ratio of liquid/solid as 1:70, ... |
