Active oxygen free radicals are intermediate metabolites produced in life activities (Tahmouzi & Ghodsi, 2014). Excessive reactive oxygen free radicals can cause damage to macromolecular substances in organisms, induce various diseases, accelerate the aging of body, and thus seriously affect human health (Al-Reza et al., 2016; Han et al., 2019; Mo et al., 2017; Ru et al., 2019). In order to reduce the damage of active oxygen radicals, antioxidants are commonly used. At present, there are two main types of antioxidants, one is synthetic and the other is natural. Synthetic antioxidants have limited therapeutic effects due to their significant toxicity, so the search for safe and effective natural antioxidants from natural resources is receiving more and more attention (Carocho et al., 2018). Many studies have shown that the natural polysaccharides isolated from plants have a good antioxidant activity (Chen et al., 2019a; Zhao et al., 2019), which can effectively scavenge free radicals in organisms and have a good health care effect (Chen et al., 2014). Therefore, it is of great significance to develop them into a new type of natural antioxidant.
