It is well known that some kinds of leaves contain a lot of antioxidants in them; however, little attention has been given to the study on the amount of antioxidants in them and the changes in the amount of antioxidants in them during their growth. Therefore, we examined the antioxidants in the leaves of persimon, moraceae, and trifoliage orange during their growth. The amount of total polyphenol tended to decrease during plants' growth, and each amount was 4.62 g/dried 100 g persimon leaf, 1.70 g/dried 100 g moraceae leaf, and 0.91 g/dried 100 g trifoliage orange leaf in April. The amount of total polyphenol in persimon leaf was 2.7~5.1 times higher than moraceae and trifoliage orange leaf. The amount of ascorbic acid also decreased during plants' growth, and each amount was 2.7~6.0 mg/dried 100 g moraceae leaf, 5.3~9.9 mg/dried 100 g persimon leaf, and 3.7~6.9 mg/dried 100 g trifoliage orange leaf. Persimon leaf was found to contain higher amount of ascorbic acid than moraceae leaf or trifoliage orange leaf. The amount of glutathione tended to decrease during plants' growth, and each average amount was 35.7 mg/dried 100 g trifoliage orange leaf, 15.8 mg/dried 100 g moraceae leaf, and 2.3 mg/dried 100 g persimon leaf. Trifoliage orange leaf contained the highest amount of glutathione. β-Carotene tended to increase during the growth, and each amount was 411.2 mg/dried 100 g moraceae leaf, 198.5 mg/dried 100 g persimon leaf, 144.1 mg/dried 100 g trifoliage orange leaf in September. α-Tocopherol also tended to increase during the growth, and each amount was 52.8 mg/dried 100 g trifoliage orange leaf, 48.6 mg/dried 100 g moraceae leaf, and 61.7 mg/dried 100 g persimon leaf in September.
