Abstract Rutabaga (Brassica napus L.) belonging to Brassicaceae family, is a rich source of polyphenols and glucosinolates. Its consumption in human diet is highly appreciated for its nutritional contribution and health benefits. Brassica napus L. is recognized as the world's most widely grown temperate oilseed crop containing erucic acid for industrial applications, plants germination, animal feed and fuel. In this work we prepared two different extracts of Rutabaga root’s pulp and peel, e.g. ultrasound assisted extract (UAE) and homogenizer assisted extract (HAE). The four extracts have been analyzed by HPLC-MS to assess the phytochemical characterization and tested by antioxidant and enzyme inhibitor assays. Rutabaga pulp and peel extracts possess tyrosinase and glucosidase inhibitory activities together with a moderate antioxidant ability. Our results show a high level of glucosinolates, in particular neoglucobrassicin in the peel extract, which let us suppose a potential application as crop in industry and as supplement in human diet.

大头菜根的果肉和果皮 (Brassica napus L.) 的化学特征、抗氧化特性和酶抑制作用

摘要 大头菜（Brassica napus L.）属于芸苔科，是多酚和硫代葡萄糖苷的丰富来源。它在人类饮食中的消费因其营养贡献和健康益处而受到高度赞赏。欧洲油菜被认为是世界上种植最广泛的温带油籽作物，含有芥酸，可用于工业应用、植物发芽、动物饲料和燃料。在这项工作中，我们制备了大头菜根的果肉和果皮的两种不同提取物，例如超声辅助提取物 (UAE) 和均质器辅助提取物 (HAE)。四种提取物已通过 HPLC-MS 进行分析，以评估植物化学特性，并通过抗氧化剂和酶抑制剂测定进行测试。大头菜果肉和果皮提取物具有酪氨酸酶和葡萄糖苷酶抑制活性以及中等抗氧化能力。
