Aqueous extract and two flavanone glycosides named 5,7-dihydroxy-4'-methoxy flavanone-5-β-D-glucopyranosyl-(l-→2)-β-D-glucopyranoside (1) and 5,5'-dihydroxy-4',7-dimethoxyflavanone-5,5'-di-0-β-D-glucopyranoside (2) obtained from the flowers of Butea monosperma were studied for evaluate their dyeing properties on cotton fibers. The stem bark of Myrica esculenta was used as natural mordant whereas SnCl2 and FeCl3 as synthetic mordants. The combination of dye with mordants showed interesting shades with excellent washing and light fastness properties. © 2014 ACG Publications. All rights reserved.
