紫娟茶主要化学成分及药理活性研究进展

Research advance in chemical constituents and pharmacological activities of Zijuan tea

紫娟茶为云南大叶群体茶树品种中的一种变种,其化学成分包含花青素类、儿茶素类、黄酮及其苷类、氨基酸、微量元素等物质,特别是含其有丰富的花青素成分。紫娟茶具有抗氧化、清除自由基、降压、抗炎、抑菌和降脂等作用,其药理活性逐渐受到学者们的关注。与其他茶相比,紫娟中含有丰富的花青素类成分,其作为一种水溶性天然色素和抗氧化剂,具有抗癌、抗肿瘤、抗炎、增强免疫能力等功能,在保健品、饮料、药品等领域受到越来越多的重视。近年来,对紫娟茶的研究逐渐增多,本文概述了紫娟茶的化学成分以及主要药理活性研究迚展,以期为紫娟茶更深入的研究和开发提供理论依据。

Zijuan tea is a kind of tea tree variety in Yunnan Daye tea(Camellia sinensis var.assamica(Mast.)).Its chemical compositions include anthocyanins,catechins,flavonoids and their glycosides,amino acids and traces trace elements and other substances,especially its abundant anthocyanins.Zijuan tea has anti-oxidation,free radical scavenging,antihypertensive,antibacterial and lipid-lowering effects,and its pharmacological activity has gradually attracted the attention of scholars.Compared with other teas,Zijuan tea is rich in anthocyanin,which acts as a water-soluble natural pigment and antioxidant,and has anti-cancer,anti-tumor and anti-inflammatory functions.More and more attention is paid in the fields of health care products,beverages,and medicines.In recent years,the research on Zijuan tea has gradually increased.This paper summarized the research progress of the chemical constituents and main pharmacological activities of Zijuan tea,in order to provide a theoretical basis for the more in-depth research and development of Zijuan tea.
