Obesity is a serious health problem that increased risk for many complications, including diabetes and cardiovascular disease. The results showed EZA, which found rich in flavonoids and phenolic compounds, exhibited an inhibitory activity on pancreatic lipase in vitro with IC(50) of 91.07 μg/mL. In vivo administration of this extract to HFD-rats lowered body weight and serum leptin level; and inhibited lipase activity of obese rats by 37% leading to notable decrease of T-Ch, TGs and LDL-c levels accompanied with an increase in HDL-c concentration in serum and liver of EZA treated HFD-rats. Moreover, the findings revealed that EZA helped to protect liver tissue from the appearance of fatty cysts. Interestingly, supplementation of EZA modulated key enzyme related to hypertension such as ACE by 36% in serum of HFD animals and improve some of serum electrolytes such as Na(+), K(+), Cl(-), Ca(2+) and Mg(2+). Moreover, EZA significantly protected the liver-kidney function by reverted back near to normal the values of the liver-kidney dysfunction indices AST&ALT, ALP, CPK and GGT activities, decreased T-Bili, creat, urea and uric acid rates. In conclusion, these results showed a strong antihypelipidemic effect of EZA which can delay the occurrence of dislipidemia and hypertension.
肥胖是一个严重的健康问题,会增加许多并发症的风险,包括糖尿病和心血管疾病。结果表明,EZA 富含类黄酮和酚类化合物,对胰脂肪酶表现出体外抑制活性,IC(50)为 91.07μg/ml。该提取物在体内给予 HFD-大鼠可降低体重和血清瘦素水平;并通过抑制肥胖大鼠的脂肪酶活性 37%,导致 T-Ch、TGs 和 LDL-c 水平显著降低,同时血清和肝脏中的 HDL-c 浓度增加。此外,研究结果表明,EZA 有助于保护肝脏组织免受脂肪囊肿的出现。有趣的是,EZA 补充剂通过 36%调节 HFD 动物血清中与高血压相关的关键酶,如 ACE,并改善一些血清电解质,如 Na(+)、K(+)、Cl(-)、Ca(2+)和 Mg(2+)。此外,EZA 还通过将肝功能和肾功能障碍指数 AST&ALT、ALP、CPK 和 GGT 活性的恢复接近正常,显著保护了肝肾功能,降低了 T-Bili、creat、urea 和尿酸水平。总之,这些结果表明 EZA 具有很强的抗高脂血症作用,可以延缓高血脂和高血压的发生。
