测定对象中各种抗氧化物质和抗氧化酶等构成总抗氧化水平。在生物学、医学和药学研究中，常常检测血浆、血清、唾液、尿液等各种体液，细胞或组织等裂解液、植物或中草药抽提液及各种抗氧化物(antioxidant)溶液的总抗氧化能力。 测定原理：DPPH·为稳定的自由基，溶于甲醇、乙醇等极性溶剂中，在 515nm 处有最大吸收。向DPPH·溶液中加入抗氧化剂时，会发生脱色反应，因此可用吸光度的变化并以 Trolox 作为对照体系量化抗氧化物质的抗氧化能力。
The total antioxidant level is constituted by various antioxidants and antioxidant enzymes in the sample. In biology, medicine, and pharmaceutical research, the total antioxidant capacity is frequently measured in various body fluids such as plasma, serum, saliva, and urine, as well as in cell or tissue lysates, plant or herbal extracts, and various antioxidant solutions. Determination principle: DPPH• is a stable radical that is soluble in polar solvents such as methanol and ethanol, with a maximum absorption at 515 nm. When an antioxidant is added to a DPPH• solution, a decolorization reaction occurs. Therefore, the change in absorbance can be used to quantify the antioxidant capacity, using Trolox as a reference standard.
