Abstract: [Objectives] To explore the extraction and in vitro antioxidant effect of astragalus polysaccharides (APS) and Ganoderma lucidum mycelia polysaccharides (GLMPS). [Methods] By studying the polysaccharides of the herbal medicinal material Astragalus membranaceus and the fungal medicinal material Ganoderma lucidum mycelia, two polysaccharides were mixed according to different proportions and concentrations by using the principle of traditional Chinese medicine compound combination. The effect of polysaccharides on the scavenging ability of hydroxyl radical system was determined by salicylic acid method. [Results] When the compound ratios of GLMPS and APS were 1:1, 1:4, 1:5, 4:1, and 5:1, the scavenging effect of compound polysaccharides was better than that of single-component polysaccharides, and with the increase of concentration, the scavenging effect increased. When the ratio of GLMPS and APS was 5:1, the hydroxyl radical scavenging rate of the compound polysaccharide reached 59.77%, which was 18.72% higher than that of single GLMPS and 28.58% higher than that of single APS. The scavenging effect of compound polysaccharide is closely related to the compound ratio and concentration. [Conclusions] APS and GLMPS can obtain better hydroxyl radical scavenging ability than single-component polysaccharides through compounding in appropriate proportions. In addition, within a suitable concentration range, as the concentration increases, the scavenging ability also increases.
