EXTRACTION AND EVALUATION OF A NATURAL DYE FROM BISTORTA AMPLEXICAULE


 Natural pigments extracted from plants are raised as a vital substitute to artificial dyes. The present study was conducted extract pigment Bistorta amplexicaule and evaluate its dyeing property, antimicrobial activity toxicity. extraction done by maceration sonication methods with 7.5% 5% yield, respectively. appeared bright- amber colored which used for fabrics food using traditional methods. suitable dying achieved 4g dye powder in 100ml water 250mg 26.2g of rice. did not indicate antibacterial against Staphylococcus aureus, Klebsiella sp., Escherichia coli Serratia marcescens disc-diffusion method. Dye albino mice assay show any mortality throughout the period (15 days). natural plant B. had potential fabric.
