Methods: Spectrophotometric and high performance liquid chromatography were used.
Results: A high vitamin C content was found mainly in brand A. A high total phenolic content was
observed in brand A, and there was no significant difference in flavonoid content between the two
brands. Cajuína had high antioxidant activity, which was confirmed by two methods. The highest
value was found for brand A by the DPPH method.
