目的 :测定粗毛淫羊藿生品及 4种不同炮制品中总黄酮的含量并作比较。方法 :采用紫外分光光度法测定含量。结果 :总黄酮含量由高到低顺序为 :生品 >清炒品 >酒炙品 >盐炙品 >羊脂炙品 ;平均回收率为96 0 1% ,RSD 0 74% (n =5 )。结论 :加热等因素致使炮制品总黄酮含量均有降低 ;而临床仍多用炮制品 ,其原因当在于辅料的协同、促进等作用 ,应作进一步深入研究 Objective : To determine and compare the total flavonoids in crude hair Epimedium and four different processed products. Method : UV spectrophotometric determination of content. Results: The order of total flavonoids from high to low was as follows: raw product> fried product> wine product> salt cake product> sheep fat product; the average recovery rate was 96 0 1%, RSD 0 74% (n = 5) . Conclusion : The heating and other factors resulted in the decrease of total flavonoids content in the processed products; while the clinical use of processed products is still more, the reason lies in the synergy and promotion of excipients, and should be further studied.
