普洱熟茶化学成分研究进展

Research progress on chemical composition of Pu-erh tea

普洱熟茶是一种独特的微生物发酵茶,由中国云南省的大叶种茶的晒干叶制成,为中国特有名茶。近年来,普洱熟茶由于其降血脂、抗氧化、减肥、抗菌等多重保健功效而备受欢迎,目前已从普洱熟茶中分离出多种功能性成分并进行了验证。该文综述了近年来国内外对普洱熟茶化学成分及主要化学成分转化的研究,特别是普洱茶中特有的加成儿茶素类成分,为进一步研究普洱熟茶的生物活性物质及其形成机制提供了一定的理论基础。

Pu-erh tea is a special microbial fermented tea produced from sun-dried leaves of large-leaf tea species(Camellia assamica)in Yunnan province,China.Pu-erh tea has become increasingly popular in recent years,which due to its multiple health benefits,such as hypolipidemic,antioxidant,antiobesity and antibacterial effects.Many functional components of Pu-erh tea have been isolated and identified,the chemical constituents and transformations of major chemical components of Pu-erh tea,especially substituted catechins,were reviewed and discussed in this paper.This review aimed to provide a theoretical basis for further investigation on bioactive compounds of Pu-erh tea and their formation mechanisms.
