The antioxidant activities were evaluated by the DPPH Radical Scavenging Activity (RSA) method and the folin ciocalteu reagent was used to determine the total phenolic content. The results showed that pigmented varieties have DPPH RSA, phenolic content, tannin, vitamin E and protein higher than non-pigmented variety. Gando Keta has DPPH RSA 91.59% higher than Latu Kala (80.63%) and Gando Bura (42.13%). In the second harvesting (first ratoon), the DPPH Radical Scavenging Activity of Gando Keta decreased (14.35%), Latu Kala (52.6%) and Gando Bura (52.49%). The total phenolic content of Gando Keta decreased 20.42%, Latu Kala (9.58%) and Gando Bura (41.19%). Thus, this study informs that Gando Keta has the best antioxidant properties compared to other varieties among local Bima-Indonesian sorghum. Copyright@ International Science Community Association
