Scenedesmus dimorphus藻渣多糖降血脂与抗氧化作用

Study on Hypolipidemic and Antioxidant Effects of Polysaccharides from Scenedesmus dimorphus Residues in Rats

摘要:

对二形栅藻（S. dimorphus）藻渣多糖的降血脂和抗氧化能力进行了研究。实验结果表明：二形栅藻藻渣多糖对大鼠体重、肝脏指数和脾脏指数的增加有一定的抑制作用，并能显著降低高血脂大鼠血清甘油三酯（TG）和MDA的含量，提高SOD酶的活力，但对总胆固醇（TC）、低密度脂蛋白胆固醇(LDL-C)和高密度脂蛋白胆固醇(HDL-C)调节作用不明显。实验结果证实二形栅藻藻渣多糖对大鼠有显著的降低血脂和抗氧化作用。本实验为二形栅藻藻渣的高值化利用提供参考。

Abstract:

The hypolipidemic and antioxidant effects of the polysaccharides from S. dimorphus residues were studied. The results showed that the polysaccharides from S. dimorphus residues have an inhibition for gaining weight, liver index and spleen index. They also could obviously drop the content of serum lipids TG and MDA, and enhanced the activity of SOD in hyperlipidemia rats. However, there is not obvious impact of the polysaccharides from S. dimorphus residues on the serum TC, HDL-C and LDL-C in hyperlipidemia rats. Therefore, the polysaccharides from S. dimorphus residues have significantly hypolipidemic and antioxidant effects. The results are useful for the high value utilization of S. dimorphus residues.
