摘要
目的:研究紫榆膏的质量标准。方法:用薄层色谱(TLC)法对紫草、当归进行定性鉴别;用高效液相色谱法对紫草中左旋紫草素进行含量测定。结果:TLC斑点圆整,分离度好,易于区别;左旋紫草素进样量在0.02032～10.29μg范围内与峰面积积分值呈良好的线性关系(r=0.9995),平均回收率为99.69%,RSD=1.18%(n=6)。结论:所建标准可用于紫榆膏的质量控制。
OBJECTIVE：To establish quality standard of Ziyu cream.METHODS：Radix Arnebiae and Angelica sinensis were identified by TLC.The content of shikonin was determined by HPLC.RESULTS：The TLC spots were round in shape and well-separated,and easy to be determined.The linear range of shikonin was 0.020 32～10.29μg with an average recovery of 99.69%（r= 0.999 5）and RSD was 1.18%（n=6）.CONCLUSION：The standard is reliable for the quality control of Ziyu cream.
