研究人员首先在计算机模型中测试了他们的理论，随后在实验中证实，表儿茶素没食子酸酯能阻止变形 链球菌在塑料牙齿及模拟牙齿上形成生物膜，从而抑制其对牙齿的伤害。 据新华社北京电 （记者李雯）美国《微生物学谱》杂志日前发布的研究显示，枫糖浆中的一种天然化 合物可能有助于对抗蛀牙，未来有望开发出成分更天然的口腔护理产品。 美国怀俄明大学的研究人员介绍，他们发现引起食物中毒的李斯特菌可以在大多数植物和木材上生长并 形成生物膜，但在枫树上却不行。于是他们利用枫树汁液和稀释的枫糖浆，分离出抑制李斯特菌附着的 化合物——表儿茶素没食子酸酯，并测试它是否会对变形链球菌产生类似的效果。变形链球菌是龋齿的 主要致病菌，它会通过在牙齿上形成生物膜（牙菌斑）并产生破坏牙釉质的酸来引发蛀牙。 《 人民日报 》（ 2025年08月16日 05 版） (责编：岳弘彬、牛镛) 关注公众号：人民网财经 ...
