The aqueous extract of flavanone glycosides were obtained from the flowers of Butea monosperma (Lam) Kuntze (Palash) as: 5,7-dihydroxy-4¹-methoxy flavanone-5-D-glucopyranosyl-(1→2)-B-D-glucopyranoside (I) and 5,5¹-dihydroxy-4¹-7-dimethoxy flavanone-5,5¹-di-O-β-D-glucopyranoside (II). The present investigation were carried out for the evaluation of their dyeing properties on cotton fibers. Flowers dye showed interesting shades with excellent washing and light fastness properties and had remarkable absorption percentages.
