摘要
The leaves of lotus are called ‘Hayeob’ ( ), which is known to have the effect of extinguishing heat, smoothing water metabolism, clearing the blood, and releasing blood(1–2). This experimental study was designed to investigate the inhibitory effects of Hayeobtan on lipid metabolism in high fat/cholesterol diet (HFCD)‐induced hypertriglyceridemia(3–4). Sprague Dawley rats were fed the HFCD diet with/without fluvastatin (Flu, positive control) 3 mg/kg/day, and HYT 100 or 200 mg/kg/day, respectively. All groups received a regular diet or HF diet, respectively, for 13 weeks. The last three groups treatment of Flu and HYT 100, and HYT200 orally for 9 weeks. Treatment of HYT markedly attenuated plasma levels of triglycerides and augmented plasma levels of high‐density lipoprotein (HDL) in HFCD‐fed rats. HYT and Flu also led to an increase in lipoprotein lipase activity in the HFCD group. On the other hand, HYT and Flu led to an decrease in fatty acid synthase and free fatty acid activity in the HFCD group. Treatment with HYT suppressed increased expressions of PPAR‐α and AMPK in HFCD rat liver or muscle. In addition, the HYT attenuated triglyceridemia by inhibition of PPAR‐γ and FABP protein expression levels and LXR and SREBP‐1 gene expression in liver or muscle. The HYT significantly prevented the development of the metabolic disturbances such as hypertriglyceridemia and hyperlipidemia. Taken together, the administration of HYT improves hypertriglyceridemia through the alteration in suppression of triglyceride synthesis and accentuated of triglyceride decomposition. These results suggested that HYT is useful in the prevention or treatment of hypertriglyceridemia‐related disorders such as triglyceride metabolism.
