Guava leaf extract in this study to evaluate the efficacy of the antioxidant content of total polyphenols was measured and electron donating ability. Total polyphenol content of 333.1 mg / g, 38.74% of the electron donating capacity, respectively. Extracts of the general composition of carbohydrates per unit to 0.2 g/100g of heavy metals appeared was not detected.
