Quantificação de ácidos fenólicos em chás de Plectranthus neochilus por cromatografia líquida de alta eficiência com detector eletroquímico

Abstract

Plectranthus neochilus Schlechter is a plant used by popular medicine to cure and/or treat diseases, symptoms and signs related to the digestive tract and abdômen and is also known by the names of “boldo miúdo”, “boldo gambá”, “boldo rasteiro”, among others. It has the largest amount of bioactive compounds with pharmacological characteristics, including phenolic acids from secondary metabolismo: gallic, protocatechuic, vanillic, p-coumaric, caffeic and ferulic acids. Several factors alter the production of secondary metabolites of the plants and consequently their quality and therapeutic value, such as rhythmocircadian, development, temperature, water availability, among other. As a result, the concentration of the six phenolic acids mentioned in Plectranthus neochilus leaf samples under different cultivation and harvesting conditions affected the synthesis of secondary metabolites of the medicinal plant studied, according to their metabolic characteristics.
