Many publications have described the potential cardioprotective action of different medicinal plants, relating this effect with blood lipid levels. However, these publications do not justify the right amount of plant administered, which can vary greatly. is a little woody plant endemic to western and southwestern Europe. We have quantified its antioxidant activity, which can be used as an indicator of its cardioprotective action. This study evaluates the antioxidant capacity of to design a feed whose hypolipidemic effects are proven in cholesterol-fed New Zealand rabbits. Antioxidant action was assessed in infusions, which were prepared with 1 or 3 g of plant in 200 mL of water by using an ABTS assay and expressed as Ascorbic acid Equivalent Antioxidant Capacity (AEAC). Aqueous infusions with infusion times of 10 min and prepared with 3 g plant exhibited the strongest antioxidant activity. showed an intermediate antioxidant capacity for the concentrations and times of the infusion tested. According to our results, we suggest incorporating 2.36 g of every 150 g of rabbit feeding stuff (15.73 g/kg). This chow decreased cholesterol, HDL-cholesterol, LDL-cholesterol, and triglycerides levels in cholesterol-fed rabbits, as well as the atherogenic index. This reduction was similar to that obtained with simvastatin.
许多出版物都描述了不同药用植物的潜在心脏保护作用,将这种作用与血脂水平联系起来。然而,这些出版物并没有说明植物的正确用量,其用量可能差异很大。 是一种原产于西欧和西南欧的小型木本植物。我们已经量化了它的抗氧化活性,这可以作为其心脏保护作用的指标。本研究评估了 的抗氧化能力,以设计一种饲料,其降血脂作用已在胆固醇喂养的新西兰兔中得到证实。使用 ABTS 测定法,通过用 1 或 3 克植物在 200 毫升水中制备的浸液评估抗氧化作用,并表示为抗坏血酸当量抗氧化能力 (AEAC)。用 3 克植物制备的浸提时间为 10 分钟的水浸液显示出最强的抗氧化活性。 对于测试的浓度和浸提时间,表现出中等的抗氧化能力。根据我们的结果,我们建议每 150 克兔饲料(15.73 克/千克)中加入 2.36 克 。这种饲料降低了胆固醇喂养兔的胆固醇、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇和甘油三酯水平,以及动脉粥样硬化指数。这种降低与辛伐他汀相似。
