甘草、甘草末和甘草流浸膏中甘草酸(G)的定量方法有重量法、比色法、极谱法、纸层析法、薄层层析法(TLC)和气相层析法(GC)等。作者等也提出过二乙胺乙基纤维素(DEAE)的简易分析方法,这些方法所得的结果彼此各异,且除DEAE法外都较费时。本文研究了高速液相层析(HLC)定量分析甘草酸的方法,并与上述几种分析方法进行了比较,最后阐明了结果差异的原因。
Quantitative methods for glycyrrhizic acid (G) in licorice root, licorice root and licorice root extract are gravimetric, colorimetric, polarographic, paper chromatography, thin layer chromatography (TLC) and gas chromatography )Wait. The authors also proposed a simple analytical method of diethylamine ethycellulose (DEAE), the results obtained by these methods are different from each other, and more time-consuming than the DEAE method. In this paper, the method of quantitative analysis of glycyrrhizic acid by high performance liquid chromatography (HLC) was studied and compared with the above methods. Finally, the reasons for the difference in results were elucidated.
