芜菁 (B. rapa) 根因其在提供必需营养素方面的卓越性能而越来越受到营养学家和注重健康的消费者的关注。多糖是白菜根中的主要生物活性物质，含有多种不同摩尔比和糖苷键类型的单糖。根据白菜根多糖（BRP）的来源、提取、分离和纯化方法，阐明了不同的结构特征和药理活性。白菜根中的多糖具有一系列营养、生物和增强健康的特性，包括抗缺氧、抗疲劳、免疫调节、降血糖和抗肿瘤抗氧化活性。本文综述了白菜根多糖的提取纯化方法、结构特征、生物活性以及结构与功能特征之间的相关性。最终，这项工作将为理解多糖结构与生物活性之间的联系以及开发新型基于 BRP 的功能食品提供有用的参考。版权所有 © 2023。由 Elsevier B.V. 出版。

Brassica rapa (B. rapa) roots are attracting increased attention from nutritionists and health-conscious customers because of their remarkable performance in supplying necessary nutrients. Polysaccharides are major biologically active substances in B. rapa roots, which come in a variety of monosaccharides with different molar ratios and glycosidic bond types. Depending on the source, extraction, separation, and purification methods of B. rapa roots, polysaccharides (BRP), different structural features, and pharmacological activities are elucidated. Polysaccharides from B. rapa roots possess a range of nutritional, biological, and health-enhancing characteristics, including anti-hypoxic, antifatigue, immunomodulatory, hypoglycemic, and anti-tumor antioxidant activities. This paper reviewed extraction and purification methods, structural features, and biological activities as well as correlations between the structural and functional characteristics of polysaccharides from the B. rapa roots. Ultimately, this work will serve as useful reference for understanding the connections between polysaccharide structure and biological activity and developing novel BRP-based functional foods.Copyright © 2023.
