Present study was aimed to elucidate hypolipidemic effect of fresh Triticum aestivum (common wheat) grass juice (GJ) in experimentally induced hypercholesterolemia in rats and to investigate its role in cholesterol excretion. Hypercholesterolemia was induced experimentally in rats by including 0.75 g% cholesterol and 1.5 g% bile salts in normal diet for 14 days. Hypercholesterolemic rats were administered fresh Triticum aestivum GJ at the dose of 5 mL/kg and 10 mL/kg and the standard drug atorvastatin 0.02% w/v in 2% gum acacia suspension at the dose of 1 mg/kg for 14 days by gavage. Blood samples were collected after 24 h of last administration and used for estimation of lipid profile. Fecal cholesterol levels were estimated using standard methods. Fresh GJ administration at 5 mL/kg and 10 mL/kg resulted in dose dependent significant decline in total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C) and very low density lipoprotein-cholesterol (VLDL-C) levels in hypercholesterolemic rats. Further, in comparison to atorvastatin, GJ administration at the dose of 10 mL/kg resulted in comparable decrease of TC, LDL-C, TG and VLDL-C levels (p > 0.05). Fecal cholesterol excretion was significantly (p < 0.05) enhanced by Triticum aestivum GJ administration. Phytochemical analysis revealed the presence of flavonoids, triterpenoids, anthraquinol, alkaloids, tannins, saponins and sterols in fresh wheat grass juice. The results of present study revealed hypolipidemic effect of Triticum aestivum GJ in hypercholesterolemic rats by increasing fecal cholesterol excretion. Fresh GJ could have potentially beneficial effect in atherosclerosis associated with hyperlipidemia.
本研究旨在阐明新鲜小麦草汁(GJ)对实验性诱导的大鼠高胆固醇血症的降血脂作用,并研究其在胆固醇排泄中的作用。通过在正常饮食中添加0.75 g%胆固醇和1.5 g%胆盐,连续14天,在大鼠中实验性诱导高胆固醇血症。给高胆固醇血症大鼠灌胃5 mL/kg和10 mL/kg剂量的新鲜小麦草汁,以及1 mg/kg剂量的标准药物阿托伐他汀(0.02% w/v于2%阿拉伯胶混悬液中),持续14天。在末次给药24小时后采集血样,用于评估血脂谱。采用标准方法测定粪便胆固醇水平。给予5 mL/kg和10 mL/kg剂量的新鲜小麦草汁可使高胆固醇血症大鼠的总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)和极低密度脂蛋白胆固醇(VLDL-C)水平呈剂量依赖性显著下降。此外,与阿托伐他汀相比,给予10 mL/kg剂量的小麦草汁可使TC、LDL-C、TG和VLDL-C水平出现类似程度的下降(p>0.05)。给予小麦草汁可显著(p<0.05)增强粪便胆固醇排泄。植物化学分析表明新鲜小麦草汁中存在黄酮类化合物、三萜类化合物、蒽醌、生物碱、单宁、皂苷和甾醇。本研究结果表明,小麦草汁通过增加粪便胆固醇排泄对高胆固醇血症大鼠具有降血脂作用。新鲜小麦草汁可能对与高脂血症相关的动脉粥样硬化具有潜在的有益作用。
