Research Article


Even though the role of all-trans lycopene from tomato in controlling atherosclerosis was reported, but no report is available on the cis-isomer of lycopene obtained from an easily available source green algae Chlorella marina. So in this study, Sprague Dawley rats fed with high-cholesterol diet were given standard drug lovastatin; algal lycopene (AL) (cis/all-trans 40:60) and tomato all-trans lycopene (TL) and the following parameters were studied. Total cholesterol, low-density lipoprotein, triglycerides were decreased significantly and the high-density lipoprotein levels were increased on treatment with AL. The activities of antioxidant enzymes catalase, superoxide dismutase, glutathione peroxidase, and glutathione reductase were found to be increased, whereas thiobarbituric acid reactive substances levels were decreased in AL when compared to the drug and TL-treated rats. The activities of inflammatory marker enzymes like cyclooxygenase, 15-lipoxygenase in monocytes and myeloperoxidase, C-reactive protein and ceruloplasmin levels in serum were found to be decreased on treatment with AL. Histopathological studies revealed that lycopene from this alga could reduce fatty liver and aortic plaque when compared to the drug and TL. Algal lycopene showed very significant antioxidant and anti-inflammatory effect in high-cholesterol fed rats. Therefore, AL from C. marina would be recommended for the treatment of hyperlipidemia.
