Mint herb, commonly used in traditional medicine, is mainly consumed in the form of teas. Mint is characterized by antioxidant, antibacterial, hypoallergenic and immunomodulatory effects, as well as is benecial to the digestive tract. It is an excellent cholagogue, low diastolic, carminative and appetite stimulant. Used in the form of inhalation against runny nose, pharyngitis and bronchitis, it works weakly antiseptic. The aim of this study was to evaluate and compare the quality
characteristics of selected mint teas from diferent producers. 19 peppermint teas, in bags and without bags, were tested. Color measurements of dried leaves were made and the qualitative and quantitative analysis of the main polyphenolic compounds in 50% methanol extracts by high-performance liquid chromatography. In addition, the content of major polyphenolic compounds in aqueous infusions was determined. Based on the results obtained, it was found that mint teas difer significantly from each other. It was observed that leaf teas have higher quality than teas in bags.
