Abstract

Objective: To make a comparative study on wild and cultivated Astragali Radix in Wuchuan, Neimenggu where is one of the geo-authentic producing areas of Astragalus membranaceus var. mongholicus. Method: This comparative study focus on shapes and properties, microscopic features of transverse section and powder of roots, qualitative evaluation of wild and cultivated Astragali Radix. Result: Wild Astragali Radix had a cylindrical main root, 2 or 3 root branches, dark brown color and many lenticels on the root bark. Cultivated Astragali Radix had a long cylindrical root, few root branches, yellowish white or light brown and fewer lenticels on the root bark. The differences of microscopic features were that the number of cork cells layers in wild Astragali Radix was bigger than that in cultivated Astragali Radix; stone cells were only observed in wild Astragali Radix; distinct annual rings in the xylem were only existed in cultivated Astragali Radix. The results of qualitative evaluation reveal that the contents of major active isoflavonoids and saponins in wild Astragali Radix are higher than those in cultivated Astragali Radix. Conclusion: There are some diagnostic differences in the main microscopic features of transverse section and powder between wild and cultivated Astragali Radix. The contents of major active isoflavonoids and saponins in wild Astragali Radix are higher than those in cultivated Astragali Radix. Our study provides important scientific evidence for reasonable and effective uses of wild and cultivated Astragali Radix in Wuchuan, and also provides a reliable basis for the quality control of Astragali Radix.
