新疆、甘肃地区甘草质量评价研究

目的 比较新疆与甘肃地区甘草的性状、鉴别特征和有效成分含量，研究在不同生长条件下我国甘草主产区的药材和饮片质量，为甘草的后续开发与利用提供理论依据。方法 采用性状鉴别法对性状进行描述，采用显微鉴别法展现甘草粉末和切片的结构特征，采用高效液相色谱法测定有效成分含量。结果 在性状方面，新疆甘草药材比甘肃甘草药材平均直径略大；在显微方面，两个产地具有基本相同的结构，但新疆家种甘草的淀粉粒数量略多，且平均粒径也略大；在含量方面，新疆甘草中甘草酸平均含量约为甘肃甘草酸平均含量的1.5倍。结论 新疆、甘肃地区甘草的鉴别和质量评价为甘草药材的质量标准研究及甘草药材的后续开发提供理论依据。

Quality Evaluation of Radix Glycyrrhizae in Xinjiang and Gansu, China

Objective To investigate the properties, identification features, and contents of effective constituents of Radix Glycyrrhizae from Xinjiang and Gansu, China, as well as the quality of the medicinal material and decoction pieces of Radix Glycyrrhizae from main producing areas with different growth conditions, and to provide a theoretical basis for further development and exploitation of Radix Glycyrrhizae. Methods Morphological identification was performed to describe the properties of Radix Glycyrrhizae, the microscopic identification method was used to display the structural features of Radix Glycyrrhizae powder and slices, and high- performance liquid chromatography was used to measure the contents of effective constituents. Results As for properties, the Radix Glycyrrhizae medicinal material from Xinjiang had a slightly larger average diameter than that from Gansu. As for microscopic features, the Radix Glycyrrhizae medicinal material from these two producing area had a basically similar structure, but Radix Glycyrrhizae planted in Xinjiang had a slightly higher number of starch granules and a slightly larger average diameter. As for the contents of effective constituents, the average content of glycyrrhizic acid in Xinjiang Radix Glycyrrhizae was about 1.5 times that in Gansu Radix Glycyrrhizae. Conclusion The identification and quality evaluation of Radix Glycyrrhizae in Xinjiang and Gansu provides a theoretical basis for the research on the quality standard and the subsequent development of Radix Glycyrrhizae.
