Abstract

Aloysia polystachya (Griseb. et Moldenke) has not been deeply investigated in past years and currently data about its chemical composition are limited. Phenolic compounds characterization can be very difficult in vegetable matrices, owing to bonds to sugar moieties or conjugation, giving rise to complex structures. In this work, methanolic extracts of Aloysia polystachya leaves were analyzed by HPLC-ESI-MS, the favourite technique for the separation and quantification of their polyphenols. To assess the complete characterization and quantification of the phenylpropanoid fraction, three different MS techniques have been coupled to HPLC: ion trap mass spectrometry (Ion Trap LC/MS), quadrupole-time of flight high resolution mass spectrometry (Q-TOF HRMS) and triple-quadrupole (TQ LC/MS) for the quantification. Eleven phenylpropanoid glycosides were identified and quantified and, among them, the compounds forsythoside A, plantainoside C, purpureaside D, martynoside and its two isomers were detected for the first time to the best of our knowledge. The results presented here could be helpful to assess the quality of this plant and could further contribute to the chemotaxonomy of the genus.
