The study analyzes the influence of plant growth promoters and biological control agents on the chemical composition and antioxidant activity (AA) in the sprouts of buckwheat. The AA of cv. Kora sprouts was higher than cv. Panda, with 110.0 µM Fe/g (FRAP-Ferric Reducing Antioxidant Power), 52.94 µM TRX (Trolox)/g (DPPH-1,1-diphenyl-2-picrylhydrazyl), 182.7 µM AAE (Ascorbic Acid Equivalent)/g (Photochemiluminescence-PCL-ACW-Water-Soluble Antioxidant Capacity) and 1.250 µM TRX/g (PCL-ACL-Lipid-Soluble Antioxidant Capacity). The highest AA was found in the sprouts grown from seeds soaked in extract and (121.31 µM Fe/g (FRAP), 56.33 µM TRX/g (DPPH), 195.6 µM AAE/g (PCL-ACW) and 1.568 µM TRX/g (PCL-ACL). These values show that the antioxidant potential of buckwheat sprouts is essentially due to the predominant hydrophilic fraction of antioxidants. The AA of the sprouts was strongly correlated with total polyphenol content.
该研究分析了植物生长促进剂和生物防治剂对荞麦芽化学成分和抗氧化活性（AA）的影响。科拉品种（cv. Kora）芽的抗氧化活性高于熊猫品种（cv. Panda），其铁还原抗氧化能力（FRAP）为110.0微摩尔铁/克，1,1-二苯基-2-苦基肼自由基清除能力（DPPH）为52.94微摩尔特洛克斯（Trolox）/克，光化学发光法测定的水溶性抗氧化能力（PCL-ACW）中的抗坏血酸当量（AAE）为182.7微摩尔/克，光化学发光法测定的脂溶性抗氧化能力（PCL-ACL）为1.250微摩尔特洛克斯/克。在浸泡于提取物和[此处提取物名称缺失]中的种子所生长的芽中发现了最高的抗氧化活性（121.31微摩尔铁/克（FRAP），56.33微摩尔特洛克斯/克（DPPH），195.6微摩尔抗坏血酸当量/克（PCL-ACW）和1.568微摩尔特洛克斯/克（PCL-ACL））。这些数值表明，荞麦芽的抗氧化潜力主要归因于抗氧化剂的主要亲水部分。芽的抗氧化活性与总多酚含量密切相关。
