Abstract

The invention belongs to the field of detection of the quality of traditional Chinese medicinal materials and in particular relates to a method for detecting the quality of radix astragali. The method comprises the steps of determining the content of astragaloside and calycosin contained in radix astragali and determining the pesticide residues of radix astragali. The method conduces to solving the technical problems that identification methods of traditional physicochemical properties are complex to operate and have limitation and the quality is difficult to regulate and control, has high degree of accuracy, is simple, convenient and fast to operate, is low in cost and has good application prospect and economic benefits.

Description

technical field [0001] The invention belongs to the field of quality detection of traditional Chinese medicinal materials, and in particular relates to a quality detection method of medicinal materials of Radix Astragali. Background technique [0002] Astragalus, containing several chemical components, including sucrose, glucuronic acid, astragaloside IV, calycosin, formononetin, astragaloside Ⅱ, astragaloside Ⅲ, astragalus polysaccharides A, B, C, D, mucilage, and various amino acids , Bitterin, astragaloside, choline, folic acid, flavan compounds and various trace elements such as selenium, silicon, zinc, cobalt, copper and molybdenum. For invigorating qi and solidifying the surface, diuretic and toxin support, evacuation of pus, astringing sores and promoting granulation. Astragalus has been on the market in my country for many years, and its clinical effects have been widely affirmed. The main components of astragaloside IV, calycosin, formononetin, astragaloside Ⅱ, an...
