中文摘要:

      花青素是茶树中重要的次生代谢产物, 具有抗氧化、抗炎、预防心血管疾病等显著的健康功效, 是紫茶叶片着色的关键物质, 其生物合成受到内源和外源的共同调控。本文对茶树花青素代谢调控机制进行系统阐述, 重点论述不同紫茶品种及特性、花青素的生物合成、调控网络、外界环境及降解机制对其积累的影响, 并对未来的研究方向进行展望。以期更好解析茶树叶片花青素生物合成的分子调控机制, 为人工精准调控茶树叶色和选育高花青素茶树品种提供参考价值。

英文摘要:

      Anthocyanidins are important secondary metabolites in tea plant with significant health benefits, such as antioxidant and anti-inflammatory properties, as well as prevention of cardiovascular diseases. They play a key role in the coloration of purple tea leaves, and their biosynthesis is regulated by both endogenous and exogenous factors. This paper systematically reviewed the metabolic regulation mechanism of anthocyanin in tea plant, with emphasis on discussing different varieties and characteristics of purple tea, biosynthesis pathways, regulatory networks, the influence of external environments, degradation mechanisms, and prospected the future research direction, so as to better analyze the molecular regulation mechanism of anthocyanin biosynthesis in tea leaves, accurately regulate leaf color in tea plant artificially, and provide reference value for cultivating anthocyanin-rich tea plant varieties.
