Studies on the extraction, optical characteristics, and ageing of natural pigments from different flower plants- A review
Divya Chandrashekhar Sanas
In order to determine the optimal dye removal process, We detailed the colour extraction procedures and solvents used to extract five distinct flowering plants (ethanol and water). five natural dyes have numerous distinct functional groups present, according to their FTIR spectra. To separate the dyes from their solutions, analytical tests such Vacuum evaporation, column chromatography, and UV spectroscopy were used. Pigment colors in floral extracts were studied using UV-Vis, and the results revealed pronounced bandgaps and higher adsorption maxima in the visible area. One of the pigments under research, Alternanthera ficoidea, has the minimum direct bandgap (1.69 eV) and Absorbed by the material value (6.33 meV) of all the pigments. The yield rate of dye extraction using water solvent increased from 11.7% to 24.7% to 11.3-32.4%.
