摘要
目的研究红芪药典标准,优化红芪药材的质量标准。方法从性状、薄层色谱鉴别、高效液相色谱(HPLC)测定、水分、总灰分、醇溶性浸出物等方面对8批红芪药材质量标准进行研究。结果红芪药材性状描述有别于以往文献记载,薄层色谱鉴别采用乙酸乙酯-三氯甲烷-水(4∶9∶1)展开系统,效果优于2010年版《中华人民共和国药典》红芪标准。以芒柄花素为对照,建立了红芪HPLC特征图谱。结论本研究所建立的红芪薄层鉴别方法简单易行、准确可靠。
Objective To study the pharmacopoeia standards of Hedysari Radix;To optimize the quality standards of Hedysari Radix medicinal materials. Methods Quality standards of eight batches of Hedysari Radix medicinal materials were studied from the aspects of properties, TLC identification, HPLC determination, the content of water and total ash, alcohol soluble extract, etc. Results The property description was different from the previous literature. The effects of TLC identification using ethyl acetate-chloroform-water(4∶9∶1) system is better than the standards in 2010 edition of Chinese Pharmacopoeia. With formononetin as reference, the HPLC characteristic spectrum of Hedysari Radix was established. Conclusion The TLC identification method is simple, accurate and reliable.
