High performance liquid chromatograms of standards and major alkaloids of five tea plant cultivars. A Standard. B Chromatograms of the main purine alkaloid substances of BXZ. C Chromatograms of the main purine alkaloid substances of FDDB. D Chromatograms of the main purine alkaloid substances of KC3H. E Chromatograms of the main purine alkaloid substances of XH3H. F Chromatograms of the main purine alkaloid substances of YSXL. G Main alkaloid components of different tea plant cultivars. The data represent the mean from three replicates. ND, not detected. Different small letters indicate a significant different difference among different treatments (P < 0.05).
