2.称取10mg抗坏血酸,1mL DMSO中,配置10mg/mL的阳性供试储备液,取200μL置于96孔板中F2以G2孔,用无水乙醇半倍稀释为不同浓度(5,2.5,1.25,0.625,0.3125,0.1562,0.0781,0.0391,0.0195mg/mL)分别置于F3-F11,G3-G11孔,F1、F12和G1、G12孔空白;
3.取200μLDMSO置于96孔板中B2以C2孔,用无水乙醇半倍稀释为不同浓度(5,2.5,1.25,0.625,0.3125,0.1562,0.0781,0.0391,0.0195mg/mL)分别置于B3-B11,C3-C11孔,B1、B12和C1、C12孔空白;
4.准确称取DPPH 3.5mg,用无水乙醇溶解转入10mL容量瓶中定容,配置成0.35mg/mL的DPPH溶液;
5.0.35mg/mL的DPPH溶液20μL加入B2-B11,D2-D11以及F2-F11孔中,C2-C11,E2-E11以及G2-G11中加入20μL无水乙醇为空白对照,轻微震荡后置于黑暗环境反应30min;
6.30min后将96孔板置于517nm工作波长下的酶标仪进行检测,重复三次测量,根据公式计算清除率。
式1,A0是对照反应在517nm处的吸光度(包括除样品之外的所有试剂),而As是样品在517nm处的吸光度。测量重复三次,选择VC作为阳性对照。
结果:Gf.6-7-23的CL50=14.538μg/mg,阳性对照Vc的CL50=15.261μg/mL,Gf.6-7-23对DPPH的清除能力与抗坏血酸效果几乎同等。
