测定了28种植物产品的抗氧化活性和总酚，包括向日葵籽、亚麻籽、小麦胚芽、荞麦和几种水果、蔬菜和药用植物。根据Folin-Ciocalteu方法测定的总酚含量为169 - 10548 mg/100 g干产品。根据β-胡萝卜素漂白法评价的甲醇提取物的抗氧化活性，表示为AOX（Δ log A（470）/min），AA（相对于对照的抑制百分比），ORR（氧化速率比）、AAC（抗氧化活性系数）的变化范围分别为0.05、53.7、0.009和51.7 ~ 0.26、99.1、0.46和969.3。总酚与抗氧化活性的相关系数达极显著水平。
The antioxidant activities and total phenolics of 28 plant products, including sunflower seeds, flaxseeds, wheat germ, buckwheat, and several fruits, vegetables, and medicinal plants were determined. The total phenolic content, determined according to the Folin-Ciocalteu method, varied from 169 to 10548 mg/100 g of dry product. Antioxidant activity of methanolic extract evaluated according to the beta-carotene bleaching method expressed as AOX (Delta log A(470)/min), AA (percent inhibition relative to control), ORR (oxidation rate ratio), and AAC (antioxidant activity coefficient) ranged from 0.05, 53.7, 0.009, and 51.7 to 0.26, 99.1, 0.46, and 969.3, respectively. The correlation coefficient between total phenolics and antioxidative activities was-statistically significant.
