Abstract

The association between the consumption of pigmented rice (Oryza sativa L.) and the improvement of human health is generating a great deal of interest among the researchers. An experiment was conducted during 2020 and 2021 at Assam Agricultural University, Jorhat, Assam to study the phytochemical profiling, antioxidant capacities and anthocyanin compositions of the 14 pigmented rice genotypes. The results were compared with the well-known traditional pigmented rice variety from Manipur, Poreiton Chakhao. The total phenolic content, total flavonoid content and total anthocyanin content ranged from 37.101 to 493.611 mg gallic acid equivalent/100 g, 53.316 to 151.667 mg quercetin equivalent/100 g and 1.006 to 13.904 mg cyanidin-3-chloride equivalent/100 g in the studied rice genotypes. The amount of rice showing 50% DPPH free radical scavenging activity (IC 50 value) ranged from 6.610 to 29.376 mg. The HPLC analysis revealed presence of both cyanidin-3-glucoside and peonidin-3-glucoside in the black pigmented rice genotypes, viz. TTB Black Rice 7, Chakhao-1, Chakhao-2 and TTB Black Rice 11. However, in the red rice genotypes analysed (Balam and Nepali Chakuwa), these two anthocyanins were not detected.

印度东北部有色水稻(Oryza sativa)的植物化学分析、抗氧化能力和花青素组成

食用色素大米(Oryza sativa L.)与改善人类健康之间的关系引起了研究人员的极大兴趣。2020年至2021年期间，在阿萨姆邦乔哈尔特的阿萨姆农业大学进行了一项实验，研究了14种色素水稻基因型的植物化学特征、抗氧化能力和花青素成分。结果与曼尼普尔著名的传统色素水稻品种Poreiton Chakhao进行了比较。在所研究的水稻基因型中，总酚含量、总黄酮含量和总花青素含量分别为没食子酸当量37.101 ~ 493.611 mg /100 g、槲皮素当量53.316 ~ 151.667 mg /100 g和花青素-3-氯当量1.006 ~ 13.904 mg /100 g。显示50% DPPH自由基清除活性的水稻量(ic50值)为6.610 ~ 29.376 mg。高效液相色谱分析显示，TTB黑米7号、Chakhao-1、Chakhao-2和TTB黑米11号基因型中均含有花青素-3-葡萄糖苷和芍药苷-3-葡萄糖苷。然而，在分析的红米基因型(Balam和Nepali Chakuwa)中，未检测到这两种花青素。
