Antihyperlipidemic and hepatoprotective activities of polysaccharide fraction from Cyclocarya paliurus in high-fat emulsion-induced hyperlipidaemic mice

The objective of this study was to analyse the structure of CPP-2, and to observe the pharmacological effects of CPP-2 on lipid metabolism and oxidative stress. CPP-2, eluted as two main fractions comprised of two polysaccharides with Mw of 307 and 3.7 kDa, was mainly consisted of rhamnose, mannose, glucose and galactose in a molar ratio of 1.00: 0.78: 3.22: 0.45. The results showed that treatment with CPP-2 could improve blood lipid levels (TC, TG, HDL-C and LDL-C), liver lipid levels (TC and TG) and antioxidant status (SOD, T-AOC, GSH-PX, MDA and LPO). In addition, the histopathological observations of mice livers and the GPT activities indicated that CPP-2 could attenuate liver cell injury. The present findings demonstrated that CPP-2 might be effective in lowering lipid and protecting against HFE-induced hyperlipidemia and non-alcoholic fatty liver.
