摘要

对哥伦比亚6个品种新鲜收获的豆芽进行了异黄酮成分分析。研究了12℃贮藏时间和外源诱导子2,6-二氯异烟酸(INA)对大豆芽合成异黄酮类化合物能力的影响。以大豆SK-7的诱导芽和非诱导芽为研究材料,根据其生长阶段(VE、VC和V1)和组织(子叶-上胚轴和下胚轴-根)对总酚含量和抗氧化活性进行了评价。异黄酮含量和抗氧化能力与品种、生育期、组织和12℃贮藏时间有关。生长阶段VE、V1和下胚轴根的总酚含量和抗氧化活性最高。总的来说,6′-O -丙二醇龙胆素、大豆苷元和龙胆素是这些品种的主要成分。大豆SK-7和Panorama 358的6′-O -丙二酸根素含量最高,分别为155.9µg/g和83.5µg/g。结果表明,INA处理显著提高了黄酮类化合物和酚类化合物的含量及抗氧化活性。这些信息可用于生产具有更多生物活性化合物的豆芽,并改善对非生物和生物胁迫的反应。

Isoflavonoid composition and antioxidant activity on elicited and non-elicited sprouts of six soy cultivars grown in Colombia
: Isoflavonoid composition of freshly harvested soy sprouts of six cultivars grown in Colombia was analyzed. Evaluations on the effect of storage time at 12 °C and exogenous application of the elicitor 2,6-dichloro isonicotinic acid (INA) were carried out to establish their influence in the ability of soy sprouts for synthesizing isoflavonoids. In addition, elicited and non-elicited sprouts of soy cultivar Soy SK-7 was assessed for total phenolic content and antioxidant activity according to the growth stage (VE, VC, and V1) and tissues (cotyledon-epicotyl and hypocotyl-root). Isoflavonoid content and antioxidant capacity were dependent on the cultivar, growth stage, tissue, and storage time at 12 °C. Growth stages VE and V1 and the hypocotyl-root exhibited the highest total phenolic content and antioxidant activity. In general, 6”-O -malonylgenistin, daidzin and genistin were the major constituents in the cultivars. Soy SK-7 and Panorama 358 displayed the highest amounts of 6”-O -malonylgenistin (155.9 µg/g) and daidzin (83.5 µg/g), respectively. Results showed that the isoflavonoids and phenolic contents and antioxidant activity were significantly increased by application of INA. This information can be useful to produce soybean sprouts with increased amounts of bioactive compounds and improved response to abiotic and biotic stresses.
