The study was conducted to evaluate the antioxidant activity by DPPH assay in leaves of Aloe vera with different developmental stages and preconditioning processes such as cutting direction, washing water temperature, and dry period for promoting bioactive utility. Antioxidant activity was increased in longer leaves than younger leaves. However, there were no significant differences in the antioxidant activities by DPPH assay of leaves with different cutting directions which was segmented transversely or longitudinally and washing water temperature at 10℃ and 40℃, and dry period at room temperature for 7 days after harvesting and first-washing. The results indicated that leaf developmental stages might be the most important factor compared to preconditioning processes in terms of the bioactive utility of Aloe vera.
