Guava is native to the tropics of the Americas and is widely distributed throughout the subtropical region. It is known to be effective in diabetes. Guava is one of the subtropical crops currently grown in Jeju and other regions. In order to search another physiological activities, we investigated the antioxidant activity of extracts after hot water extracts of Guava (Psidium guajava L.) at four stages of development. As a result, antioxidative activity was found in all leaf extracts. The highest antioxidant activity was observed in the youngest leaves at the drying, and in the Old Red and Mature Green leaves at the freezing storage.
