Abstract

The aim of this study was to assess the antioxidant activities of B. rapa var. parachinensis leaves and seeds. The aqueous extraction of leaves and seeds were analysed for total amount of phenolic, flavonoids, ascorbic acid, chlorophylls, carotenoids, 2, 2-diphenyl-1-picryl-hydrazil (DPPH) radical scavenging activity and reducing power capacity. The total amount of biochemical compounds showed different variety between leaves and seeds. The content of vitamin C was incredibly higher in seeds while the quantity of chlorophyll, carotenoids and phenolic contents was higher in leaves. DPPH scavenging activity of seed extraction displayed higher percent of inhabitation in comparison with leaves. The reduce power of seed and leaves at 10 mg extract were 0.46±0.024 and 1.03±0.058, respectively. The data were analysed by one-way ANOVA multiple comparison test followed by Duncan’s multiple range test.
