摘　　要：以主成分分析(PCA)和相关性分析(CA)法研究黄芪中主要有效成分与生态因子的相关性,探究影响黄芪主要成分积累的生态因子.结果表明:山西产地黄芪中的黄芪甲苷、毛蕊异黄酮苷、芒柄花苷、山奈酚和黄芪多糖的含量显著高于内蒙古和甘肃两地.影响黄芪化学成分含量的气候因子主要为年均相对湿度、年日照时数及7月均温.影响黄芪化学成分含量的土壤元素主要为钙,且钙在一定范围内与毛蕊异黄酮苷、山柰酚、芒柄花苷、槲皮素、黄芪多糖的含量呈负相关.Principal component analysis（ PCA） and correlation analysis（ CA） were applied to analyze the correlation of the main chemical components in Astragalus membranaceus var. mongholicus and ecological factors. The results showed that the contents of astragaloside,campanulin,ononin,kaempferol and astragalus polysaccharides（ APS） of A. membranaceus var. mongholicus produced in Shanxi were significantly higher than in Inner Mongolia and Gansu. The main climatic factors for affecting the contents of chemical ingredients in A. membranaceus var. mongholicus were annual average relative humidity,sunshine hours and average July temperature. Calcium was the main factor in the soil affecting the chemical ingredient contents,and calcium was negatively correlated with the contents of calycosin glycosides,kaempferol,ononin,quercetin and APS in A. membranaceus var.mongholicus within a certain range.
