Hepatoprotective, Antihyperlipidemic and Radical Scavenging Activity of Hawthorn (Crataegus oxyacantha) and Rosemary (Rosmarinus officinalis) on Alcoholic Liver Disease

Abstract

Alcohol catabolism produces oxidative stress, causing cell death and inflammation in liver tissue principally. Hawthorn (Crataegus oxyacantha) and Rosemary (Rosmarinus officinalis) are medicinal plants that have shown a potent antioxidant activity related with anti-inflammatory properties. The objective of this study was the evaluation of Hawthorn and Rosemary methanol extracts as preventive treatment in alcoholic liver disease (ALD). ALD rat model was used to measure serum hepatic enzyme levels (AST, ALT, γ-GT and ACP), total bilirubin, liver glycogen, lipid peroxidation, total antioxidant capacity (TAC) and serum lipid profile (total cholesterol, triglycerides, LDL and HDL) as well as histopathological analysis in hepatic tissues was recorder. Phytotreatments showed preventive effect, decreasing AST, γ-GT, lipid peroxidation and bilirubin indictors while TAC and liver glycogen stores increase. Interestingly, Rosemary diminished the levels of ALT and ACP. Remarkable both treatments show liver tissue damage reduction. Hawthorn proved antihyperlipidemic effect, eviting increase in all lipid indicators, while Rosemary showed antihyperlipidemic effect only in LDL levels without affecting HDL levels. The results indicate that Hawthorn and Rosemary treatments have different mechanisms of action; however they show hepatoprotective effect against ALD in rat model. Hawthorn and Rosemary could be used to prevent or help in the treatment of ALD.
