Green Extraction, Characterization, Applications and Antimicrobial Analysis of Natural Dye from Phyllanthus emblica

Abstract

Global consciousness towards the organic value of eco-friendly products has attracted the interest of people towards the use of naturally dyed textiles and organic mordants. The present study has been focused not only on exploring the bio-colourant activity of Phyllanthus emblica (Amala) but also on the application of natural mordant for textile dyeing and analysis of its medicinal properties. It has been discovered from the investigation that biomordants like extract of Aloe vera’s as well as extract of mango’s bark extract were able to evince their characteristic colour ameliorate behaviour close to synthetic ones. Besides, the disparity in absorbance band in ultraviolet spectroscopy, distinction in functional groups and differences in surface morphology of two extracted dyes were observed that provided information on colour variation in the cotton fabrics. An eagle gray shade and brown-hued on the cotton fabric were noticed from water and ethanol extracted dyes, respectively. Further, it is confirmed that the natural dyes contain bioactive phytochemicals like tannins, phenols and flavonoids that provide a significant antibacterial activity which will help it to be beneficially utilized in protective medical clothing.
