Abstract:Although tea leaves are predominantly yellow-green，green，dark green，and so on，purple leaf tea cultivars are also known to exist in nature.The variety in the color of tea leaves is due to the presence of pigments such as anthocyanin.A significant positive correlation was found between tea color and anthocyanin content.According to traditional knowledge，the quality of tea made from anthocyanin-rich purple bud leaves is poor.However，recent research has shown that Pu'er tea made from purple bud leaves possesses characteristics of high quality tea，such as green tea，black tea and Pu'er tea.Although their characteristics differ from those of green bud leaves，purple bud leaves have high antioxidant activity and confer certain health benefits，including free radical removal and blood pressure reduction.Therefore，anthocyanin-rich purple bud leaf tea is considered to be highly valuable for scientific research and economic development.Its favorability among researchers and consumers worldwide has led to the popularization of the cultivation of purple bud leaf tea varieties and the development of purple bud leaf tea products.In this study，purple bud leaf tea was reviewed on aspects including anthocyanin types，influencing factors，health benefits，and product development to provide reference for its comprehensive utilization.
