        abstract = {Natural dyes and pigments are produced by living organisms such as plants, animals, fungi, and microorganisms. Dyes and Pigments are chemical compounds that absorb light in the wavelength range of the visible region. The need for dyes and pigments has increased according to the human desire for colors in the required amounts used in food, medicine, textiles, etc. The main objective of this study was to isolate natural pigments from Hibiscus rosa sinensis (Malvaceae) and Tagetes erecta (Asteraceae) and predict of antioxidant compounds from plants. The ethanolic extracts were used for the isolation and separation of antioxidant compounds using different chromatographic techniques, such as column chromatography, thin layer chromatography, and spectroscopic analytical methods. The antioxidant activity of the isolated pure compounds was determined using the modified 1,1-diphenyl-2- picrylhydrazyl (DPPH) and reducing power methods. The main mechanism of action of antioxidants is to improve the immune system in the human body by preventing the formation of free radicals. The isolated pure pigment fractions obtained from the ethanolic extracts of the selected plant species could be a good source of natural antioxidants.},
