菊苣提取物和菊粉降脂活性研究

以300日龄商品代尼克T粉壳蛋鸡为试验动物,研究了菊苣提取物和菊粉对血清脂质、蛋黄总脂和胆固醇的影响.结果显示,0.1%菊苣提取物组、2.0%菊苣提取物组和0.1%菊粉组血清胆固醇(TC)、甘油三脂(TG)、低密度脂蛋白(LDL-C)均显著低于对照组(P<0.05),其中0.1%菊苣提取物组TC降低36.47%,TG降低40.71%,LDL-C降低36.09%,0.1%菊粉组LDL-C降低16.23%,差异极显著(P<0.01);2.0%菊苣提取物组高密度脂蛋白(HDL-C)比对照组高23.19%,差异极显著(P<0.01);2.0%菊苣提取物组蛋黄总脂和蛋黄胆固醇显著降低(P<0.05).表明菊苣提取物和菊粉均具有降血脂活性,但菊苣提取物比菊粉活性更强;菊苣提取物还具有降低蛋黄总脂和胆固醇的作用.

Decreasing Lipid in Serum with Extracts from Cichorium intybus Roots and Inulin

The effects of the extract from Cichorium intybus L.roots and inulin on lipid in serum and egg total lipid contents and triglycerides were studied in this experiment.Nick T commercial layers(n=300) were fed diets without the extract from C.intybus roots and inulin(control) or containing 0.1% or 2.0% chicory extract from C.intybus roots or inulin.The results showed that layers fed 0.1% or 2.0% chicory extract from C.intybus roots or 0.1% inulin diets had significantly decreased the total serum cholesterol(TC),triglycerides(TG) and low density lipoprotein cholesterol(LDL-C) concentrations(P<0.05).The layers were fed diets containing 0.1% chicory extract to the diet had lowered the TC by 36.47%,lowered the TG by 40.71%,lowered the LDL-C by 36.09% in comparison with control group.The layers were fed diets containing 0.1% inulin had lowered the LDL-C by 16.23%(P<0.01) in comparison with control group.The layers were fed diets containing 2.0% chicory extract had significantly lowered the total egg cholesterol and triglycerides in comparison with control group(P<0.05).The results of this study suggested that the extract from C.intybus roots and inulin are able to improve lipid meta-bolism observed in layers,and extract from C.intybus roots is better than inulin.
