  Abstract:

  Three solvents of different polarities (water, methanol and 1% NaOH

  solution) were used to extract dyes that produced different shades from

  dried sunflower (Helianthus annuus) petal. The extraction procedures

  using different solvent types were carried out separately. The dye extracts

  were thereafter subjected to Fourier Transform Infrared Spectrometry

  (FT-IR) analysis for characterization in terms of functional groups. The

  intensities of the... More
