Abstract

Watermelon (Citrullus vulgaris L.) is a summer fruit typical to help fatigue systemic absorption is getting better. The goal of this study is to screen antioxidant activity to ensure the possibility as a functional material for exocarp of watermelon. Watermelon was extracted with 70% methanol, 70% ethanol, chloroform:methanol (CM, 2:1, v/v). Total phenol contents were 12.01 mg/g, 8.89 mg/g, 3.53 mg/g in the 70% methanol, 70% ethanol, CM, in that order, respectively. Total flavonoid content, DPPH radical scavenging activity, ABTS radical scavenging activity, ferric reducing antioxidant power (FRAP), ${\beta}$-carotene bleaching assay were 70% methanol extract remarkably higher than the other extracts. And these results showed the same trend of total phenol content. From the above results shows that watermelon was effective on the antioxidative activity.
