Abstract
In the present study, orthogonal experiment (L9 (3)4) was used to optimize the extraction process of Sagittaria sagittifolia L. polysaccharides (SSP) with subcritical water, and the antioxidant activities of polysaccharides were also investigated. The results showed that the optimum extraction conditions were obtained when pH, extraction temperature, extraction time, and liquid to solid ratio were 7, 170 °C, 16 min and 30:1 (mL/g), respectively. In addition, DPPH/ABTS radical scavenging rate and Fe3+ reducing power of polysaccharides exhibited a certain dose-effect relationship. Furthermore, both yield and antioxidant activities of polysaccharides with subcritical water extraction (SWE) were higher than traditional hot water extraction (HWE). The above results showed that SWE was an effective technique to extract and separate polysaccharides from Sagittaria sagittifolia L., which may be potentially applied in the related polysaccharides extraction.Entities:
