摘要
摘要: 通过1,1-二苯基-2-三硝基苯肼(1,1-diphenyl-2-picrylhydrazyl,DPPH)自由基清除试验和2,2-偶氮二(2-甲基丙基咪)二盐酸盐(2,2-azobis-(2-amidinopropane)dihydrochloride,AAPH)诱导红细胞溶血试验评价菊花、金银花、槐花、代代花、白扁豆花水提物和水提物的复配物(菊花50%,槐花18%,白扁豆花15%,代代花12%,金银花5%)的抗氧化性,并讨论五种药食同源花的协同抗氧化作用。结果表明五种药食同源花的提取物及其复配物均具有一定程度的抗氧化能力。在DPPH体系中,根据自由基的半数清除率(IC50值),各提取物抗氧化能力大小顺序为复配物(IC50=97.83 μg/mL) > 槐花(IC50=98.63 μg/mL) > 菊花(IC50=140.79 μg/mL) > 金银花(IC50=146.35 μg/mL) > 代代花(IC50=692.24 μg/mL) > 白扁豆花(IC50=701.51 μg/mL),复配物表现出明显的协同抗氧化效果。AAPH诱导红细胞溶血体系中,复配物和槐花提取物表现出很强的溶血抑制作用,而金银花、菊花、代代花以及白扁豆花提取物仅表现出较弱的抑制作用。剂量在50~300 μg/mL时槐花提取物对红细胞的溶血抑制率小于复配物,当剂量达到300 μg/mL时,槐花提取物和复配物对红细胞的溶血抑制率分别为77.83%±1.85%和80.94%±1.46%,这说明五种药食同源花提取物之间存在协同抗氧化作用。
Abstract: The DPPH radical scavenging test and the AAPH-induced erythrocyte hemolysis test were used to evaluate the antioxidant properties of the five kinds of medicinal food homology flower extracts and the compound(chrysanthemum 50%,Sophora japonica 18%,flos lablab albus 15%,seville orange flower 12%,honeysuckle 5%)in a certain proportion. The results showed that the extracts and the mixture all had a certain degree of antioxidant capacity. According to the half clearance rate of free radicals(IC50),the order of antioxidant capacity in DPPH system was as follows:Compound(IC50=97.83 μg/mL)>Sophora japonica(IC50=98.63 μg/mL)>chrysanthemum(IC50=140.79 μg/mL)>honeysuckle(IC50=146.35 μg/mL)>seville orange flower(IC50=692.24 μg/mL)>flos lablab albus(IC50=701.51 μg/mL). The compound showed obvious synergistic antioxidant effect. In AAPH-induced red blood cell hemolysis system,the extracts of Sophora japonica and formulations showed strong inhibitory effects on hemolysis,while the extracts of honeysuckle,chrysanthemum,seville orange flower,and flos lablab albus only exhibited slight inhibitory effects,indicating that there was synergistic effect between the five kinds of medicine food homology flowers. When the dose was between 50 and 300 μg/mL,the hemolytic inhibition rate of Sophora japonica extract on erythrocytes was less than that of the compound,and when the dose reached 300 μg/mL,the inhibition rates were 77.83%±1.85% and 80.94%±1.46% respectively,which showed that there was a synergistic antioxidant effect between the five kinds of herb extracts.
