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 3.7kDa, 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.
本研究旨在分析 CPP-2 的结构，并观察 CPP-2 对脂代谢和氧化应激的药理作用。CPP-2 洗脱后得到两个主要部分，均由两种多糖组成，Mw 分别为 307 和 3.7kDa，主要由鼠李糖、甘露糖、葡萄糖和半乳糖组成，摩尔比为 1.00:0.78:3.22:0.45。结果表明，CPP-2 可改善血脂水平（TC、TG、HDL-C 和 LDL-C）、肝脂水平（TC 和 TG）和抗氧化状态（SOD、T-AOC、GSH-PX、MDA 和 LPO）。此外，小鼠肝脏的组织病理学观察和 GPT 活性表明，CPP-2 可减轻肝细胞损伤。本研究结果表明，CPP-2 可能有效降低血脂，预防 HFE 诱导的高脂血症和非酒精性脂肪肝。
