Abstract

Nasturtium officinale W. T Aiton or “watercress” (Brassicaceae) is a nutritionally valuable plant that is the richest source of carotenoids, polyphenols, iron, calcium, iodine, folic acid, essential vitamins and minerals. It is traditionally used for their appetiser, anti-scorbutic, stimulant, diuretic and detoxifying properties. The present study was conducted to investigate the antioxidant potential, phytochemical contents (total phenolic, flavonoids and tannin contents) as well as a preliminary phytochemical screening of different extract of aerial parts of Nasturtium officinale collected from the Kumaun region. The different extracts showed significant antioxidant activity as well as total phenolic, flavonoids and tannin contents. The preliminary phytochemical screening showed the presence of several phytochemical constituents such as carbohydrates, proteins, amino acids, glycosides, alkaloids and others. The hydroalcoholic extract possess significantly (P<0.05) higher antioxidant potential with IC50 value (0.333 mg/ml, 0.509mg/ml)and EC50 value (3.537 mg/ml) by 2,2-diphenyl-1-picrylhydrazyl(DPPH), 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid)(ABTS), and ferric-reducing antioxidant power (FRAP) methods, respectively, as well as highest total tannin, flavonoid and phenolic contents among all the extracts. These results provide substantial evidence that the plant Nasturtium officinalehas antioxidant potential and valuable sources of phytochemicals.
北阿坎德邦库马恩地区野生牛蒡不同提取物抗氧化能力和植物化学成分的比较研究
Nasturtium officinale W.T Aiton或“豆瓣菜”(Brassicaceae)是一种营养价值很高的植物,富含类胡萝卜素、多酚、铁、钙、碘、叶酸、必需维生素和矿物质。传统上,它具有开胃、抗坏血病、兴奋剂、利尿和解毒的特性。本研究旨在研究Kumaun地区采集的姜地上部分不同提取物的抗氧化潜力、植物化学含量(总酚、黄酮和单宁含量)以及初步的植物化学筛选。不同提取物具有显著的抗氧化活性,总酚、黄酮和单宁含量也较高。初步植物化学筛选显示存在几种植物化学成分,如碳水化合物、蛋白质、氨基酸、糖苷、生物碱等。2,2-二苯基-1-苦基肼(DPPH)、2,2-锌基双(3-乙基苯并噻唑啉-6-磺酸)和铁还原抗氧化能力(FRAP)方法分别使水醇提取物具有显著(P<0.05)高的抗氧化潜力,IC50值分别为0.333mg/ml、0.509mg/ml和3.537mg/ml,总单宁含量最高,所有提取物中黄酮类和酚类的含量。这些结果提供了大量的证据,证明植物牛蒡具有抗氧化潜力和宝贵的植物化学物质来源。
