甘草为最常用的中药。甘草酸(Glyc-yrrhizic acid)是其主要有效成分之一。傅克治等曾报道用重量法测定黑龙江省野生与实验栽培甘草根中的甘草酸含量。李荣春等用高效液相色谱(HPLC)法测定过西北地区产的甘草浸膏中甘草酸的含量。为了探讨制订合理栽培甘草药材的质量标准和最佳采集期,我们用HPLC法测定了黑龙江省人工栽培1、2、3年生甘草实生根中甘草酸的含量,并与同地野生商品根作了比较。
Licorice is the most commonly used traditional Chinese medicine. Glyc-yrrhizic acid is one of its main active ingredients. Fu Kezhi et al. reported the determination of glycyrrhizic acid in wild and experimentally cultivated licorice roots in Heilongjiang province by gravimetric method. Li Rongchun et al. measured the content of glycyrrhizic acid in licorice extract produced in Northwest China by high performance liquid chromatography (HPLC). In order to discuss the development of a reasonable standard for cultivating Ganyin medicinal materials and the best collection period, we determined the content of glycyrrhizic acid in the roots of 1, 2 and 3 years of cultivated Glycyrrhiza uralensis in Heilongjiang Province by HPLC.
