Table 5: Concentration of caffeine, rutoside and astragalin in P-1–P-10 products after methanol and water extraction. The letters next to values represent [PERSON]’s HSD post hoc results, different letters (a–i) indicate significant differences between homogeneous groups of yerba mate products for each organic compound (\(p<0.05\)).
