Abstract

Besides being an excellent source of high-quality nutrients, legumes are deposits of antinutritional factors (ANFs) that serve as natural defences against herbivory and pathogens. This investigation aimed to study the concentration of different ANFs in 13 green gram (Vigna radiata (L.) Wilczek) cultivars and explore how varietal differences affect their levels. Ten improved, and three local cultivars of green gram were evaluated for antinutritional content using different spectrophotometric assays. Results revealed variability across cultivars with 0.45 to 1.14 g/100 g of phytic acid, 1.11 to 1.99 g/100 g of saponins, 0.91 to 1.78 mg CE/g of tannins, 17.17 to 25.55 mg GAE/g of total phenolic content, 4.41 to 10.44 TUI/mg of trypsin inhibitors, 0.15 to 0.28 g/100 g of raffinose, 0.14 to 0.36 g/100 g stachyose and 1.60 to 2.88 g/100 g of verbascose. These significant variations highlight the wide range of ANF composition found among green gram cultivars. Such data could aid in exploring the nutraceutical and pharmacological potential of these compounds.

青禾秆（Vigna radiata (L.) Wilczek）改良品种和地方栽培品种抗营养素的评估

豆科植物除了是优质营养物质的绝佳来源外，还富含抗营养因子（ANFs），可作为抵御食草动物和病原体的天然防御手段。这项调查旨在研究 13 个青蒜（Vigna radiata (L.) Wilczek）栽培品种中不同 ANFs 的浓度，并探讨品种差异如何影响其含量。采用不同的分光光度测定法，对 10 个改良青稞品种和 3 个当地青稞品种的抗营养物质含量进行了评估。结果显示，不同栽培品种的植酸含量存在差异，分别为 0.45 至 1.14 克/100 克、1.11 至 1.99 克/100 克皂甙、0.91 至 1.78 毫克 CE/克单宁、17.17 至 25.总酚含量为 17.17 至 25.55 毫克 GAE/克，胰蛋白酶抑制剂为 4.41 至 10.44 TUI/毫克，棉子糖为 0.15 至 0.28 克/100 克，水苏糖为 0.14 至 0.36 克/100 克，马鞭草糖为 1.60 至 2.88 克/100 克。这些明显的差异突出表明，青克栽培品种的 ANF 成分差异很大。这些数据有助于探索这些化合物的营养保健和药理潜力。
