【摘要】 目的建立肤痒颗粒的鉴别和含量测定的方法。方法采用TLC法鉴别制剂中的苍耳子、红花;采用HPLC法测定阿魏酸的含量。结果TLC分离效果好,斑点清晰;阿魏酸含量在0.038~1.230μg范围内有良好的线性关系(r=0.9999),平均回收率为97.49%,RSD=1.32%(n=6)。结论方法专属性强、重复性好,简便易行,可用于该制剂的质量控制。更多还原

【Abstract】 OBJECTIVE To establish an identification and a content determination methods for Fuyang granule.METHODS Fructus xanthii and Flos carthami was identified by TLC.The content of ferulic acid was determined by HPLC.RESULTS The TLC identification was distinct and the spots were clear.The linear range of ferulic acid was 0.038-1.230 μg(r=0.9999).The mean recovery was 97.49% with RSD of 1.32%(n=6).CONCLUSION These methods are specific,accurate and simple,which can be used for the quality control of Fuyang granules.更多还原
