Poster: Comparing volatile compounds among brands of Argentinian yerba mate (Ilex paraguariensis) using high-resolution GC/Q-TOF

In this study, high resolution GC-QTOF data were used to analyse yerba mate extracts of four different brands

Yerba mate, a traditional South American herbal tea is brewed from the leaves and stems of the Ilex paraguariensis plant. This beverage contains the stimulant caffeine and other bioactive compounds and has gained a wide popularity worldwide.
In this study, high resolution GC-QTOF data were used to analyse yerba mate extracts of four different brands

  • Profiling of yerba mate extracts of four different brands identified 386 compounds using 7250 GC/Q-TOF
  • Heatmap visualization as well as statistical analysis followed by hierarchical clustering identified significant differences between the brands with respect to a variety of compound groups
  • The most dramatic trends were observed with phenolic compounds, furanones, pyrazines and PAHs
