Chlorogenic acids (CGAs) are known as an important class of natural products found in different plant species and are of great interest in diverse research fields. Described as powerful antioxidant agents, these compounds can be found in high concentrations in commonly consumed foods and beverages and in herbal preparations traditionally used in Chinese, Ayurvedic, European, and popular medicines from the new world and are responsible for several pharmacological activities. Considering that diverse mechanisms may possibly be involved in plant metabolite production, herein we evaluated if CGA postharvest accumulation can be a consequence of processes other than anabolism. The objective was to compare the concentrations of chlorogenic acids in leaves subjected to different time-controlled periods of drying at room temperature. A quantitative method, using ultraperformance liquid chromatography tandem mass spectrometry, was developed to monitor the content of CGAs in coffee, lemon, Brazilian cherry, and rose...
