The current study was carried out to estimate the protective effect of methanolic extract of Chaetomorpha gracilis (MECG) against High Cholesterol Diet (HCD) induced erythrocyte damage in mice. The results of the in vitro assay showed that MECG have higher antioxidant capacities in the DPPH, TAC, ABTS, NBT, NO. inhibition assays. The HPLC analysis confirmed that this potential antioxidant seems to be due to the active compounds, in particular polyphenols, flavonoids. HCD promoted oxidative stress with a rise the level of malonaldehyde (MDA), advanced oxidation protein product (AOPP) levels and a significant decrease of the Vitamin C content, as well the antioxidant enzyme activities such as superoxide dismutase and glutathione peroxidase. In addition, HCD treatment caused significant lipid profile disorders via increase the cholesterol, triglycerides and LDL levels and reduction HDL-Ch level. A statistically significant decrease of Mg2+ and Ca2+ ATPase activities accompanied with a severe damage in the erythrocytes structure and hematological parameters alterations were also noted in hypercholesterolemic mice. Pre-treatment with MECG significantly restored biochemical markers and pathological lesions. It can be suggest that supplementation of MECG displays high potential to quench free radicals and attenuates high cholesterol diet induced erythrocytes oxidative stress and related damages.
