  • * Hot and cold mate infusions were prepared with 80°C and 5°C water, respectively.

  • The infusion made with yerba mate was removed and fresh water at the appropriate temperature was added to the leaves every 5 min. The results are shown for infusions 1, 3, 6, and 12, which correspond to the infusions removed at 5, 15, 30, and 60 min.

  • The estimated totals were calculated by fitting regression lines between the four measurements.
