Quantification of saponins in extractive solution of mate leaves (Ilex paraguariensis A. St. Hil.).
Mate (Ilex paraguariensis A. St. Hil.) is a raw material used to prepare popular beverages in South America, whose healthy effects have been pointed out. ⋯ The inter-day coefficient of variation was 6.77% and 7.79% for matesaponin 1 and matesaponin 3, respectively. The analysis of plants from Brazilian States Mato Grosso do Sul and Rio Grande do Sul showed the predominance of matesaponins 1, 2, and 3 in the corresponding extractive solution. The sum of these three saponins ranged between 3 and 10 mg/g for mature leaves in the majority of sampled plants.
