ObjectiveThe use of natural phytoconstituents for food and as nutritional supplements is an easiest way to be healthier. Anthraquinone pigments have been traditionally used for various purposes viz. food colorants, textile staining, color paints and medicines. Rubia cordifolia L. is a perennial, herbaceous climbing plant belonging to family Rubiaceae. This plant contain substantial amounts of anthraquinones, especially in the roots. The present study deals with the bioactivity evaluation of phytoconstituents viz. alizarin and purpurin from Rubia cordifolia.MethodsThe DNA protective and antioxidant potential of alizarin and purpurin was evaluated using different in vitro assays viz. DNA protection assay, ABTS assay, DPPH assay, Ferric ion reduction potential and Phosphomolybdenum assay.ResultsAlizarin and purpurin exhibited good free radical scavenging activity in various assays. In DNA protection assay, alizarin showed more DNA protection against hydroxyl radicals generated by Fenton's reagent in comparison to purpurin.ConclusionsBeing potent antioxidants, these natural coloring compounds can be boon to the food industry as nutraceuticals. Further, these phytochemicals can be explored for their anticancer activity and may serve as potent cancer chemopreventive molecules.
