The aim of this study was to investigate the effects of three different drying methods (tray drying, drum drying, and freeze drying) on some physicochemical properties and antioxidant activity of Cnidoscolus aconitifolius. Freeze-drying resulted in the dried Cnidoscolus aconitifolius showing the lowest moisture content and the highest lightness and green color. In addition, freeze-dried Cnidoscolus aconitifolius had higher contents of total phenolics, total flavonoids, and antioxidant activity (FRAP Assay) than Cnidoscolus aconitifolius dried by tray drying and drum drying. However, phytochemicals were not affected by the different drying methods. Therefore, freeze-drying the leaves of Cnidoscolus aconitifolius gave higher values in physicochemical properties and antioxidant activity.
