建立黄芪药材质量标准,研究不同产地黄芪药材的质量。采用高效液相色谱法(HPLC),对我国7个省68个黄芪样品进行了芒柄花素成分的含量测定,以芒柄花素含量作为衡量优劣指标。7个省68个黄芪药材样品检测结果表明,不同产地黄芪药材芒柄花素成分的含量差异较大,其中:山西>内蒙>甘肃>辽宁;不同品种黄芪药材芒柄花素成分的含量差异较大,其中:栽培品种<野生品种;生长年限不同,芒柄花素成分的含量也不同,其中:二年生>四年生>五年生>三年生。采用HPLC进行黄芪药材的质量评价切实可行,为制药企业选用黄芪药材提供科学、可靠的依据。
Establish the quality standard of Radix Astragali and study the quality of Radix Astragali in different areas. The content of formononin in 68 samples of Astragalus from seven provinces in China was determined by high performance liquid chromatography (HPLC), and the content of formononetin was used as a measure of superiority and inferiority. The results of 68 samples of Radix Astragali in seven provinces show that there are significant differences in the content of formononin among the Astragalus medicinal materials in different areas, among which, Shanxi> Inner Mongolia> Gansu> Liaoning; Large, of which: cultivars four years> five years> three years. It is practicable to use HPLC to evaluate the quality of Astragalus medicinal materials and provide a scientific and reliable basis for the pharmaceutical enterprises to choose Astragalus medicinal materials.
