Phytochemical Screening and Antimicrobial Activity of Curcuma longa Natural Dye

Abstract

Spectrometric and antimicrobial activities of natural colourants and dyed silk have been studied. Textile materials and clothing are known to be susceptible to microbial attack, as these provide large surface area and absorb moisture required for microbial growth. Natural dye Curcuma longa were tested against common pathogens Escherichia coli and Staphylococcus aureus. Curcuma longa dye was most effective and showed maximum zone of inhibition thereby indicating best antimicrobial activity against all the microbes tested. These textiles dyed with these natural dyes can be very useful in developing clothing for infants, elderly and infirm people to protect them against common infections.
