Abstract:
The study was aimed to research the influence of glucose consumption of HepG2 cell and insulin-resistance of HepG2 cell administrated with protein -free polysaccharide from A nnonae Squamosae Semen ( ASS ) . Crude polysaccharide from ASS was prepared by water extraction and alcohol precipitation method . Its protein was removed by sevag method . The content of its total sugar was measured by phenol-sulfuric acid method . Besides , the influences of glucose consumption of HepG2 cell and insulin-resistance of HepG2 cell administrated with different concentrations of protein-free polysaccharide were determined . The result showed that protein-free polysaccharide from ASS can slightly improve the glucose consumption of HepG2 cell , which was related to its concentration . The protein-free polysaccharide from ASS can obviously promote insulin-resis-tance of HepG2 cell . When the drug concentration was 0 . 08 mg?mL-1 , the effect is the best ( P < 0 . 01 ) . Be-sides , the protein-free polysaccharide from ASS had certain synergistic effect as physiological insulin . It was concluded that the protein-free polysaccharide from ASS had good in v itro hypoglycemic effect .
