Abstract

This study analysed 100 plants employed in Brazil as ingredients to infusions for their caffeic acid, 3-caffeoyl-quinic acid (3-CQA), 4-caffeoylquinic acid (4-CQA), 5-caffeoylquinic acid (5-CQA), 3,4-dicaffeoylquinic acid (3,4-DQA), 3,5-dicaffeoylquinic acid (3,5-DQA), and 4,5-dicaffeoylquinic acid (4,5-DQA) contents. The samples were collected from public markets and analysed using ultra-high performance liquid chromatography (UPLC). The highest concentrations of chlorogenic acids were found in yerba mate (Ilex paraguariensis), 9,2 g.100 g(-1), white tea (Camellia sinensis), winter's bark (Drimys winteri), green tea (Camellia sinensis), elderflower (Sambucus nigra), and Boeluneria caudata (known as assa-peixe in Brazil), 1,1 g.100 g(-1). The present work showcased the investigation of chlorogenic acids in a wide range of plants not yet studied in this regard and also resulted in a comparative table which explores the content of six isomers in the samples.
