摘要: 在体外模拟人体消化环境,研究分析杀青、不杀青茶鲜叶和茶花水提液在体外对各种胆酸盐的结合能力,同时探讨杀青、不杀青茶鲜叶和茶花中的主要功能性成分茶多酚与胆酸盐结合的相关关系。结果表明:杀青茶鲜叶的水提液结合胆酸盐的能力最强,其次是茶花水提液、不杀青茶鲜叶的水提液。结合各种胆酸盐能力与各种水提液的茶多酚含量呈显著性相关关系,结果初步证明茶叶、茶花的功能性成分对人体具有降血脂功能。

Abstract: The bile salt-binding capabilities of water extracts from fresh tea leaves, fixed fresh tea leaves and tea flowers were compared. Meanwhile, the correlation between tea polyphenol content and bile salt-binding capacity in vitro in a simulated human digestive environment was also explored. The results revealed a significant correlation between bile salt-binding capacity and tea polyphenol content. Water extract from fixed fresh tea leaves exhibited the strongest bile salt-binding capability, followed by water extracts from tea flowers and fresh tea leaves. Therefore, water extracts from fresh tea leaves and tea flowers have functional components that can reduce blood lipid.

Key words: fresh tea leaves, tea flower, tea polyphenol, bile salt, binding
