Astragalan Polysaccharide (ASP) and Astragaloside (AS) are two main ingredients with activity in Scutellaria Astragalan. In order to extract ASP and AS at the same time, the extracting technology is studied. The optimum times and concentrations of ethanol were determined in ethanol extraction followed by water extraction method. In addition, the higher yield and content of ASP and AS were obtained through combining ultra filtration and the resin absorption method.
