Characterization and antioxidant properties of polysaccharides from flowers of Sophora japonica L. (Huaihua)
Sophora japonica L. flower polysaccharides (SJFP) were extracted with hot water, the crude polysaccharides were de-proteinized by Sevag method and fractionized by DEAE-52 column chromatogram. Five fragments were obtained, namely SJFP-A, SJFP-B1, SJFP-B2, SJFP-B3 and SJFP-B4. SJFP-A and SJFP-B3 were further purified by Superdex G-200 filtration column chromatography. The resulted two fractions SJFP-AA and SJFP-BB were...
