    Three solvents of different polarities (water, methanol and 1% NaOHsolution) were used to extract dyes that produced different shades fromdried sunflower (Helianthus annuus) petal. The extraction proceduresusing different solvent types were carried out separately. The dye extractswere thereafter subjected to Fourier Transform Infrared Spectrometry(FT-IR) analysis for characterization in terms of functional groups. Theintensities of the...
