中文摘要:

      花青素是一种水溶性天然色素和抗氧化剂, 具有抗肿瘤、防衰老、防辐射等功能。紫娟茶则因富含花青素而具有紫茎、紫叶、紫芽的特点。紫娟茶因具有很强的抗氧化活性和显著的降血压效果而逐渐成为备受消费者青睐的新兴保健饮品。近年来, 对紫娟茶花青素的研究相对增多, 本文概述了紫娟茶花青素的提取、分离纯化、组分鉴定、稳定性和生理功能等方面的研究进展, 也就目前的研究现状指出了存在的问题及解决对策, 以期为紫娟茶花青素的深度开发和综合利用提供一定参考。

英文摘要:

      Anthocyanin is a kind of water-soluble natural pigment and antioxidant, which has many functions, such as anti-tumor, anti-aging, radiation and so on. The stem, bud and leaf of Zijuan tea are purple, because of its rich in anthocyanin. Zijuan tea gradually becomes a popular emerging health drink due to its strong antioxidant activity and significant antihypertensive effect. In recent years, the research on the anthocyanin from Zijuan tea has been increased. This paper summarized the research progress of extraction, isolation and purification, component identification, stability and physiological function of anthocyanin from Zijuan tea, and pointed out the existing problems and solving methods in the current research, in order to provide some references for the exploitation and utilization of anthocyanin from Zijuan tea.
