Hypercholesterolemia is the presence of high levels of cholesterol in the blood, and it is regarded as a risk factor for cardiovascular disease due to the effects of cholesterol. The objective of this study was to investigate the effects of unripe Rubus coreanus Miquel (uRC) extract on lipid metabolism in hypercholesterolemic mice fed a high cholesterol diet (HC). uRC 50 (unripe R. coreanus 5% ethanol extract 50 mg/kg/day), uRC 100 (unripe R. coreanus 5% ethanol extract 100 mg/kg/day), uRC 300 (unripe R. coreanus 5% ethanol extract 300 mg/kg/day), and BO (borage seed oil containing minimum of 20% ${\gamma}$-linolenic acid 30 mg/kg/day) were orally administered for 60 days after HC. Oral administration of uRC 50, uRC 100, uRC 300, and BO significantly reduced serum total-cholesterol, triglyceride, LDL-cholesterol, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, atherogenic index, and cardiac risk factor levels. Similarly, uRC treatment elevated serum HDL-cholesterol levels. These results suggest that unripe R. coreanus extract could be established as a functional food for the improvement of lipid metabolism.
