摘要: In this study, a CE-MS method has been developed to carry out the qualitative characterization of lemon verbena (Lippia citriodora) extract for first time. The CE and ESI-MS parameters were optimized with respect resolution, analysis time peak shape in order maximize number compounds detected sensitivity their determination. use two different MS analyzers, TOF-MS IT-MS, enabled tentative identification major components extract. Thus, using method, 16 determined. Some them have previously identified by HPLC methods, although four also found such as asperuloside, tuberonic acid glucoside or 5'-hydroxyjasmonic 5'-O-glucoside, shanzhiside ixoside. These results demonstrate that generates data complementary those obtainable HPLC-MS it is particularly suited plant metabolites.
