Does PCP1 improve liver pathology and metabolic parameters in NAFLD mice?
PCP1 extracted from Polygonatum cyrtonema Hua shows potential as a natural ingredient for treating NAFLD by improving liver pathology, lipid metabolism, and gut microbiota in a mouse model.
The chemical structure and pharmacological activity of Polygonatum cyrtonema Hua polysaccharides have garnered significant attention in recent years. In this study, a homogeneous polysaccharide, PCP1, was extracted from P. cyrtonema Hua rhizomes and purified. Monosaccharide composition analysis showed that PCP1 is primarily composed of fructose, glucose, and mannose. Chemical structure analysis showed that the main chain of PCP1 is composed mainly of →1)-β-D-Fruf-(2→ and →1,6)-β-D-Fruf-(2→, with small amounts of →6)-α-D-Glcp-(1→, →4)-β-D-Manp-(1→, and β-D-Glcp-(1→. The side chain is β-D-Fruf-(2→ linked at C-6 of →1,6)-β-D-Fruf-(2→. In vivo experiments showed that PCP1 mitigates liver pathological damage, improves abnormal lipid metabolism and oxidative stress, promotes the production of short-chain fatty acids, and balances the composition of the intestinal microbiota in non-alcoholic fatty liver disease (NAFLD) mice. Thus, PCP1 can be used as a natural ingredient in functional foods for the treatment of NAFLD.
