EXTRACTION OF CURCUMIN PIGMENT AND STUDY ITS EFFICIENCY IN DYEING OF SCOURED COTTON FABRIC AND AS ANTIBACTERIAL AGENT

Abstract

Extraction of curcumin pigment as dyestuff and Antibacterial agent from
Tumeric (Curcuma xanthorrhizia) tubers was studied .also, the Qualitative chemical
tests was done for determine active materials in crud turmeric extract.
The curcumin pigment was isolated and partially scrubbed by using organic
solvents. Detection by HPLC and TLC proved the isolated pigment is Curcumin
with partial purity compared to the standard curcumin.
The curcumin showed ahigh efficiency of dyeing for scoured cotton fabric at
concentration 25% of curcumin and active biological effect against Gram – positive
pathogenic bacteria with large inhibition zones from 12mm to 33mm by using Agar
wells diffusion method.
The results proved ability of curcumin on dyeing of cotton cloth fabric and
antibacterial activity against bathogenic bacteria
