Progress in Application and Biological Activity of Radix Astragali in Health Foods

Radix Astragali, the dried roots of Astragalus membranaceus (Fisch.) Bunge var. mongholicus (Bunge) Hsiao or
Astragalus membranaceus (Fisch.) Bunge, is a traditional Chinese medicine tonic with a wide range of medicinal values. Its
major constituents such as polysaccharides, saponins, flavonoids, amino acids and trace elements have been investigated.
Due to the anti-tumor, immune-enhancing, anti-aging, liver-protecting, myocardial contractility-enhancing and diuretic
effects, these chemical components are widely used in clinical treatment of related diseases and health promotion. In this
article, pharmacological and health-promoting effects of bioactive components of Radix Astragali are reviewed and
explored. Based on the bioactive components of Radix Astragali and its important roles in clinical treatment of some
diseases, this study will provide corresponding guidance and theoretical references for the development of health foods
containing Radix Astragali.
