摘要
目的通过对黄芪擦剂中大黄素的含量测定,为制定黄芪擦剂质量标准提供依据。方法双波长薄层扫描法。结果平均回收率为98.19%,RSD=1.90%,n=5。结论测定结果准确、稳定、灵敏度高、重现性好,该法可作为黄芪擦剂质量标准的参考。
[Objective] To develop a method of dual-wavelength thin layer chromatographic scanning to determine the content of emodin in Huangqi liniment. [Methods] The content of the emodin in the Huangqi liniment was determined by thin layer chromatography scanning. [Result] Average recovery=97.1%; RSD=1.90%; n = 5. [Condusoons] The method is approved accurate, stable, highly sensitive and recurrent. It can be the reference of Huangqi liniment standard.
