Huangqi (Astragali Radix) is the dry root of Mongol Milkvetch (Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao) and Membranous Milkvetch (Astragalus membranaceus (Fisch.) Bge.), which is a major medicinal material in Gansu Province. It mainly contains Astragali Radix polysaccharides, flavonoids, saponins, alkaloids, amino acids, trace elements, organic acids and other chemical components. The pharmacological effects of Huangqi mainly focus on improving immunity, anti-oxidation, anti-tumor, protecting cardiovascular, promoting body metabolism, lowering blood sugar, diuresis and decreasing swelling. Based on literature retrieval, the distribution of resources, chemical components and pharmacological effects of Astragalus are reviewed and summarized. The quality markers (Q-Marker) of Astragali Radix are predicted based on traditional medicinal properties, efficacy, chemical components and different compatibility. The chemical components of Astragali Radix polysaccharide, ononin, calycosin, formononetin, astragaloside Ⅰ, astragaloside Ⅱ, and astragaloside Ⅳ were predicted by the analysis, providing a scientific basis for the quality control of Astragali Radix.
