摘要:
According to response surface methodology (RSM), the extraction conditions of ultrasound-assisted extraction of polysaccharide from the rinds of Garcinia mangostana L. (GMRP) were optimized and determined. The optimal conditions obtained through optimization were: the liquid to material ratio was 40 mL/g, ultrasonic power was 288 W and extraction time was 65 min. The average extraction rate of GMRP was 14.73%. Ac - GMRP was obtained by acetylation of GMRP, and the antioxidant activities of the two polysaccharides were compared in vitro. The results indicated that the antioxidant capacity of polysaccharide obtained after acetylation was significantly improved compared with that of GMRP. In conclusion, chemical modification of polysaccharide is an effective measure to improve its properties to a certain extent. Meanwhile, it implies that GMRP has great research value and potential.
