Abstract
In this paper a novel method for extraction and separation of total flavones and total astragalosides from Radix astragali using a resin method is suggested. Ethanol is used as the extractant, the macroporous absorption resin modeled H-107 is used to enrich the astragalus extract, and the macroporous strong base anion resin D-280 is used to separate the total flavones and the total astragalosides. This method allows a good yield of total flavones of 600 mg/100 g Radix astragali, a purity of 94.2%, and a yield of total astragalosides of 28 mg/100 g Radix astragali.
