Phenolic acid-rich extract of sweet basil restores cholesterol and triglycerides metabolism in high fat diet-fed mice: A comparison with fenofibrate - 07/12/13
Abstract |
Many spices are often added to foods as additives to enhance organoleptic qualities, such as flavor, aroma and color. Sweet basil (Ocimum basilicum L.) family of Lamiaceae is widely used in cooking for its culinary attributes. In this study, we aimed at the investigation of the hypocholesterolemic and hypotriglyceridemic activities of the basil phenolic acid-rich extract in high fat diet-induced hyperlipemic mice. Hyperlipemia was developed by a high fat diet containing cholesterol, lard and cholic acid. At the beginning of the experiment, animals were divided into three groups, one of them served as normolipidemic control group (NCG), the second hyperlipidemic control group (HCG) and the third basil-treated group (BTG). After 5weeks of treatment, basil phenolic acid-rich extract significantly decreased plasma total cholesterol, triglycerides and LDL-cholesterol (−42%,−42% and −86%, respectively, P<0.001). However, HDL-cholesterol was increased (+79%, P<0.001). The extract reduced the atherogenic index and LDL/HDL-C ratio (−88% and −94%, respectively, P<0.001). The reductions of liver total cholesterol and triglycerides were of −50% (P<0.01) and −58% (P<0.01), respectively. The hypolipemic effect of the phenolic acid-rich extract is comparable to that exerted by fenofibrate. This drug significantly reduced plasma total cholesterol, triglycerides and LDL-cholesterol (−25.5%, −51%, and −83.5%, respectively, P<0.001) and increased plasma HDL-cholesterol (+136%, P<0.001). On the other hand, fenofibrate significantly decreased atherogenic index and LDL/HDL-cholesterol ratio (−91% and −93%, respectively, P<0.001). The fenofibrate decreased hepatic total cholesterol by 59.5% and triglycerides by 72%, respectively (P<0.01). HPLC analysis led to identify four major compounds: caftaric acid, cafeic acid, chicoric acid and rosmarinic acid. In conclusion, the Sweet basil contains phenolic products that are able to lower hyperlipidemia and prevent atherosclerosis.
