摘要： Purple teas are gaining popularity due to their significant health benefits. This study analyzed flavonoid metabolites in the second leaves of three purple tea varieties with stable purple shoots-'Hongfei' (HF), 'Danfei' (DF), and 'Ziya 24 ' (ZY24)-using UPLC-MS/MS, with 'Yinghong 9 ' (YH9), a green tea, as the control. The most abundant anthocyanins were cyanidin-3-O-glucoside, cyanidin-O-syringic acid, and pelargonidin-3-O-glucoside in HF, while ZY24 and DF accumulated additional delphinidin and petunidin derivatives. DF also contained malvidin-3-O-galactoside. Furthermore, 22 significantly enriched non-anthocyanin flavonoids were identified as potential co-pigments contributing to the vibrant leaf coloration. These findings reveal key anthocyanin and flavonoid profiles responsible for the distinct purple hues in the tender shoots of different purple tea varieties.
