Solvent fractions (n-hexane, cholorofrom, methanol) and fractions containing sterols of Jolyna laminarioides was evaluated in triton-induced and high-fat-diet induced hyperlipidemic rats. Oral administration of J. laminarioides significantly reduced the elevated level of serum total cholesterol, triglycerides and LDL-c, both in triton induced and high fat diet induced hyperlipidemic rat models with increased serum HDL-c. Chloroform: methanol fraction (2:1) and n-hexane fraction containing sterol showed promising results in reducing LDL-c. The methanol fraction showed hypolipidemic effect by increasing HDL-c (90%). The extracts and fractions of the seaweed also decreased the increased level of cardiac and hepatic marker enzymes beside lowering lipid profile. J. laminarioides exhibited high anti-hyperlipidemic effects both in triton induced and high fat diet induced hyperlipidemic rats.

The study evaluated the anti-hyperlipidemic effects of myrcenol and curzerene on a high fat diet induced hyperlipidemia rat model. Thirty male albino rats were fed on a high-fat diet for four months. The HFD-induced hyperperlipidemia rats were treated with rosuvastatin (10 mg/kg), curzerene (130 mg/kg) and myrcenol (100 mg/kg) for four weeks.

Background: Piperine, a secondary metabolite, affects the antihyperlipidemic effect of Ezetimibe (EZ). Hyperlipidemia is one of the independent risk factors for cardiovascular disorders such as atherosclerosis. Antihyperlipidemic drugs are essential for reducing cardiovascular events and patient mortality.

The objective of this study was to examine the hypolipidemic effect and potential mechanism of action of green radish polysaccharide (GRP) in hyperlipidemic mice. We found that in mice fed a high-fat diet, supplementing with GRP reduced body weight and liver index, significantly improved serum lipid levels and markers of liver damage, and mitigated oxidative stress and inflammation. Mechanistically, in these hyperlipidemic mice, the size of fat cells was reduced by GRP, and the abnormal accumulation of lipid droplets was reduced.

This study explores the therapeutic potential of ω-3 algal oil (rich in DHA) and ω-7 sea buckthorn oil (rich in palmitoleic acid) in addressing hyperlipidemia and associated metabolic disorders. These oils regulate lipid metabolism through the PPARγ-LXRα-ABCA1/ABCG1 signaling pathway, reducing cholesterol accumulation, oxidative stress, and inflammation. In high-fat diet-induced hyperlipidemic mice, supplementation with these oils significantly improved lipid profiles, alleviated hepatic steatosis, and promoted cardiovascular health.
