摘要:

为了研制抗氧化中药多糖制剂,在前期研究的基础上,选择抗氧化活性较强的枸杞多糖(LBP)、白术多糖(AMP)、当归多糖(CAP)、党参多糖(CPP)、大蒜多糖(GP)、百合多糖(LP)、五味子多糖(SCP)、硒化枸杞多糖(sLBP)、硒化白术多糖(sAMP)、硒化当归多糖(sCAP)为组分药,以糖含量按照多糖-硒化多糖9∶1的比例组成18个复方,比较它们的抗氧化活性。体外试验,比较18个复方对3种自由基的清除能力;体内试验,雏鸡免疫新城疫苗时分别注射高、低剂量的3个复方,测定血清3种抗氧化酶和MDA含量的动态变化。体外试验结果显示,18个复方的5个浓度对DPPH自由基、羟自由基和ABTS自由基均有不同程度的清除能力,LBP-sAMP、CAP-sLBP和CAP-sAMP的能力较强。体内试验结果显示,6个复方组在4个时间点的血清CAT、SOD、GSH-Px活性多高于或显著高于对照组,MDA含量均低于(多显著低于)对照组;CAP-sLBP组的3种抗氧化酶活性均为最高、MDA含量最低。18个复方均有不同程度的抗氧化活性,CAP-sLBP在18个复方中的抗氧化活性最强,可以考虑作为多糖类抗氧化制剂的候选方。

Abstract:

In order to develop the antioxidant polysaccharide preparations, based on our previous researches, 18 compounds composed with Lycium barbarum polysaccharide (LBP), Atractylodes macrocephala polysaccharide (AMP), Chinese angelica polysaccharide (CAP), Codonopsis pilosula polysaccharide (CPP), Garlic polysaccharide (GP), Lily polysaccharide (LP), Schisandra chinensis polysaccharide (SCP), selenizing LBP (sLBP), selenizing AMP (sAMP), and selenizing CAP (sCAP) with stronger antioxidant activities according to carbohydrate content at 9:1 ratio of polysaccharide to selenizing polysaccharide were chose. Their antioxidant activities were compared. In vitro tests, the scavenging abilities of 18 compounds were compared for 3 kinds of free radicals. In vivo tests, the chicks were injected respectively with 3 compounds each at high and low dosage when they were vaccinated with Newcastle disease vaccine, and the dynamic changes of serum contents of 3 antioxidases and MDA were determined. The results of in vitro tests showed that 18 compounds each at 5 concentrations had different extent scavenging abilities for DPPH radical, hydroxyl radical and ABTS radicals, and the abilities of LBP-sAMP, CAP-sLBP, and CAP-sAMP were stronger. The results of in vivo test showed that in 6 compound groups at 4 time points, the activities of CAT, SOD and GSH-Px were higher or significantly higher than those in control group, and MDA contents were lower or significantly lower than those in control group. In CAP-sLBP group, 3 antioxidases activities were the highest and MDA contents were the lowest. These results indicate that 18 compounds possess differen extent antioxidant activities, the activity of CAP-sLBP is the strongest among 18 compounds and can be considered as the candidate of the antioxidant polysaccharide preparation.
