In this communication, we used electrochemical sensor for recording the electrochemical profiles of eleven species of Yulania spp. from leaf extract. Two solvents and two buffer conditions were used for electrochemical fingerprints collection. Their electrochemical fingerprints can be converted to different patterns and consequently for species recognition. The results indicate the pattern recognition is much convenient than that of the recognition of species directly using voltammetric signal. The current information in electrochemical fingerprinting represents the type and amount of electrochemically active molecules, which linked to the genetic differences among the plants. Therefore, the electrochemical fingerprints were applied for further phylogenetic study. The phylogenetic tree deduced from voltametric curves is divided into three main groups. The first clade contains Y. denudate, Liriodendron chinense, Y. cylindrica, Y. biondii, Y. sprengeri. The second clade contains Y. zenii, Y. liliiflora, Y. kobus, and Y. amoena. The third clade contains Y. × soulangeana, Manglietia fordiana and Y. sinostellata. In addition, Y. salicifolia is not in these main clades. The results demonstrate that electrochemical fingerprinting can be used as a com-plementary tool in the study of phylogenetics.
