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96.01% ,RSD0.74% (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。

Contents of General Flavonoides in Epimedium acuminatum Franch. and Its Differently processed Products

Objective: Determining and comparing the contents of general flavonoides in four kinds of differently processed products of Epimedium acuminatum .

Result: The contents were found in the following seguence: unprocessed product, clearly fried product, alcohol broiled product, salt broiled product, sheep fat broiled product. The average recovery rate was 96.01%,with a 0.74% RSD(n =5). Conclusion: Heatomg causes the contents of general flavonoides in the processed products to decrease. These processed products are still often used in clinical treatment, for the reason that the adjuvant features certain coordinating and promoting functions. The study is to be pursued further.
