In the present study, we investigated the preliminary structure, in vitro antioxidant and in vivo hepatoprotective activities of polysaccharides from Cyclina sinensis (CSPS). The analytic results of Fourier transform-infrared spectroscopy indicated the presence of α-type glycosidic linkages in CSPS-1 or CSPS-2, and the average molecular weights for CSPS-1, CSPS-2 and CSPS-3 were 69, 81 and 101kDa,...
Optimization of extraction, preliminary characterization and hepatoprotective activity of polysaccharides from Stachys flordana Schuttl. ex Benth. (SFPS) were investigated in the present study. Firstly, the optimal conditions for extraction of SFPS were obtained by a Box-Behnken design as follows: extraction temperature 94°C, extracting time 4h and ratio of water to material 19mg/ml. Then, the analysis...
