Radish ( L.) greens are consumed as a source of nutrition, and their polysaccharides such as rhamnogalacturonan-I possess certain beneficial properties. This study investigated the prebiotic effects of a radish green polysaccharide (RGP) on gut health and obesity. The prebiotic activity of RGP was evaluated based on the pH changes and short-chain fatty acids (SCFAs) concentration. The results showed that 0.5% RGP had a higher prebiotic activity score than inulin and increased SCFAs production in all five prebiotic strains. Moreover, RGP inhibited fat accumulation in 3T3-L1 adipocytes, indicating its potential to reduce obesity. Overall, these findings suggested that the polysaccharide of radish greens has prebiotic effects and may serve as a beneficial prebiotic for gut health and obesity.
萝卜（L.）叶作为一种营养来源被食用，其多糖如鼠李半乳糖醛酸聚糖-I具有一定的有益特性。本研究调查了萝卜叶多糖（RGP）对肠道健康和肥胖的益生元效应。基于pH变化和短链脂肪酸（SCFAs）浓度评估了RGP的益生元活性。结果表明，0.5%的RGP比菊粉具有更高的益生元活性评分，并增加了所有五种益生元菌株中SCFAs的产生。此外，RGP抑制了3T3-L1脂肪细胞中的脂肪积累，表明其具有减轻肥胖的潜力。总体而言，这些发现表明萝卜叶多糖具有益生元效应，可能作为一种有益的益生元促进肠道健康并减轻肥胖。
