A green approach towards utilization of Floral wastes for the extraction of Natural Colorants

The present study is focused on the utilization of floral wastes for the extraction of natural colorants. Waste flowers were collected from various sites of temples, garden, domestic and decorative areas and identified as Rosahybrid, Tageteserecta, Spathodeacampanulata, Bougainvilleaglabra, and Euphorbiamili. Identification and characterization of extracted colorants was done using thin layer chromatography (TLC), UV Spectroscopy and Fourier Transform Infra-red spectroscopy (FT-IR) analysis. Antimicrobial and antioxidant properties of extracted natural colorants were evaluated. Applicability of extracted colorants as natural dye and biofertilizer was also evaluated. It can be concluded that the natural colorants extracted from the floral wastes can be used in textile and pharmaceutical industries. In addition, contamination free natural colorants can also serve as safe biofertilizer.
