Electrochemical Identification of Yulania spp. by Fingerprinting of Leaves Using Glassy Carbon Electrode

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