Abstract

The seeds of nine China-grown radish cultivars were analyzed for their phytochemical composition, antioxidant properties and ACE-inhibitory activity. Radish seeds contained 36.87–43.06% (w/w) oils, whereas 64.55–69.26% of the fatty acids were monounsaturated and 20.33–25.11% were polyunsaturated. The levels of δ- tocopherol (552.24–670.31 μg/g seed oils) and lutein (4.82–8.95 μg/g seed oils) differed in cultivars. The nine cultivars were varied in total phenolics, flavonoids, and free phenolic acids, but not in proanthocyanidins. Seed extracts of Hybrid #63, Tou Xin Hong, and Hybrid #72 showed stronger DPPH radical scavenging capacity, ORAC, and FRAP than others (p<0.05). The Yanzhi #2 extracts exhibited a strong ACE-inhibitory activity, which was positively correlated with vanillic acid contents (r = 0.890, p = 0.001). It provides evidence on developing value-added utilization of radish seeds or seed fractions such as oil and flour as nutraceuticals or functional food ingredients.

萝卜种子的植物化学成分、抗氧化能力和ace抑制活性

对9个国产萝卜品种的种子进行了植物化学成分、抗氧化性能和ace抑制活性分析。萝卜籽含油量为36.87 ~ 43.06% (w/w)，单不饱和脂肪酸占64.55 ~ 69.26%，多不饱和脂肪酸占20.33 ~ 25.11%。不同品种的δ-生育酚(552.24 ~ 670.31 μg/g)和叶黄素(4.82 ~ 8.95 μg/g)含量存在差异。9个品种的总酚类物质、总黄酮和游离酚酸含量存在差异，但原花青素含量无差异。杂种63号、头心红和杂种72号种子提取物对DPPH自由基的清除能力、ORAC和FRAP均强于其他品种(p<0.05)。烟治2号提取物具有较强的ace抑制活性，其抑制活性与香草酸含量呈正相关(r = 0.890, p = 0.001)。它为开发萝卜种子或种子馏分(如油和面粉)作为营养品或功能性食品成分的增值利用提供了证据。

期刊介绍： The Journal of Applied Botany and Food Quality is the Open Access journal of the German Society for Quality Research on Plant Foods and the Section Applied Botany of the German Botanical Society. It provides a platform for scientists to disseminate recent results of applied plant research in plant physiology and plant ecology, plant biotechnology, plant breeding and cultivation, phytomedicine, plant nutrition, plant stress and resistance, plant microbiology, plant analysis (including -omics techniques), and plant food chemistry. The articles have a clear focus on botanical and plant quality aspects and contain new and innovative information based on state-of-the-art methodologies.
