The determination of Vitamin B6 (VB6) derivated in tea plant was described by using high performance liquid chromatography with fluorescence detector. The results indicated that, the contents of VB6 in tea leaves, tender stem and roots are 3.36 μg/g, 1.27 μg/g and 0.18 μg/g fresh weight, respectively. The constituent ratio of VB6 derivatives are as follows: pyridoxine 21%, pyridoxal 2.4%, pyridoxamine 19.3%, pyridoxal 5´-phosphate 40.8% and pyridoxamine 5´-phosphate 17.9%. The content of VB6 in tea leaves increased with maturity of leaf, and decreased with aging of leaf.
