摘　　要：目的 :建立薄层扫描法测定气滞胃痛颗粒剂中延胡索乙素含量的方法。方法 :样品经硅胶 G吸附后 ,用甲醇等溶剂提取处理 ,展开后于 λs=4 30 nm,λr=5 5 0 nm处扫描。结果 :本法稳定、准确、重现性好。平均回收率为 99.16 % ,RSD为 1.4 3%。结论 :可为延胡索乙素的含量测定提供参考。Object:To establish a TLC scanning method to determine tetrahydropalmatine in Qizhiweitong granules. Methods: The sample was absorbed by Kieselguhr and extracted with ethanol and the other solvent so on. The spots was scanned at λs=430 nm,λr=550 nm. Results: This method was reliable and the obtained results were stable with good reproducibility. The average recovery was 99.16% and RSD was 1.43%. Conclusion: This method can provide reliable guidance for the content determination of tetrahydropalmatine preparations.
