目的 :制订肿节风片质量标准。方法 :紫外分光光度法测定了总黄酮的含量 ,对肿节风药材进行了薄层色谱鉴别。结果 :加标回收率平均 98.1 % (RSD =2 .3% ,n =6) ,r =0 .99996,重复性RSD =1 .2 3% (n =6) ,精密度RSD=1 .1 4 % (n =6)结论 :方法稳定、可靠 ,可作为该制剂的质量控制方法之一。
Purpose : To establish the quality standard of swollen air patch. Methods: The content of total flavonoids was determined by UV spectrophotometry. RESULTS: The average recoveries of spiked samples were 98.1% (RSD =2.3%, n =6), r = .99996, repeatability RSD = 1.23% (n = 6), and the precision RSD = 1.1. 4 % (n = 6) Conclusion: The method is stable and reliable and can be used as one of the quality control methods for this preparation.
