摘要:

为了研制抗氧化中药多糖制剂,比较了枸杞多糖(LBP)、白术多糖(AMP)和当归多糖(CAP)对鸡胚肝细胞(CEL)的抗氧化能力的影响,以维生素C(VC)为对照。首先测定了4个药对CEL的安全浓度,然后取安全浓度范围内3种浓度的各药分别加入到CEL的培养体系中,培养24 h后加入H2O2攻击1 h,测定细胞活力(A570 nm)、细胞内ROS含量、GSH-Px和SOD的活性。结果显示,H2O2组的A570 nm值最小、ROS含量最高、GSH-Px和SOD活性最低,均与细胞对照组的差异显著(P<0.05);3个多糖组和VC组的A570 nm值均大于或显著大于、ROS含量均低于或显著低于、GSH-Px和SOD活性均高于或显著高于H2O2组,高浓度的作用最显著(P<0.05);LBP组3个浓度的作用均强于同浓度的AMP组和CAP组,相当于甚至优于VC。结果表明,3种多糖均具有较强的抗氧化活性,能够抵抗H2O2攻击引起的鸡胚肝细胞活力降低、细胞内ROS含量升高和抗氧化酶活性降低,从而增强鸡胚肝细胞的抗氧化能力,LBP的作用最强,可以考虑作为多糖类抗氧化剂。

Abstract:

In order to develop the antioxidative polysaccharide preparations, the effects of Lycum barbarum polysaccharide(LBP), Atractylodes macrocephala polysaccharide(AMP) and Chinese Angelica polysaccharide(CAP), on resisting oxidative damage ability of Chicken embryo liver cells(CEL) were compared, vitamin C(VC) were used as control. The safe concentrations of four drugs on CEL were determined. Then they at three concentrations within safe concentrations were respectively added into cultivation system of CEL. After cultivation of 24 hours, the cells were attacked by H2O2 for an hour, the cellular vitality(A570 nm value), intra-cellular ROS content, GSH-Px and SOD activities were assayed. The result showed that the A570 nm values in H2O2 group were the lowest, ROS contents were the highest and the activities of GSH-Px and SOD were the lowest, which there were significant differences as compared with cell control group(P<0.05). The A570 nm values in 3 polysaccharides and VC groups were higher or significantly higher, ROS contents were lower or significantly lower and the activities of GSH-Px and SOD were higher or significantly higher than those in H2O2 group, especially in high concentrations(P<0.05), the actions were most significant. The actions of LBP at 3 concentrations were stronger than those of AMP and CAP at same concentration, and equivalent even superior to VC. The results indicate that three kinds of polysaccharides all possess stronger antioxidant activity, can resist the CEL vitality depress, intra-cellular ROS contents elevation and antioxidase activities decline caused by H2O2 attack, thus strengthen CEL ability of oxidation resistance, LBP has the strongest activity and can be considered as polysaccharid antioxidant.
