Abstract
Natural pigments from Crocus sativus stigmas were used for the dyeing of cotton and wool fibres after treatment with the enzymes alpha-amyla se and trypsin, respectively, The separation of various compounds and pigment constituents of the stigmas was effected by fractionation of t he methanolic extract on a silica gel column, and the use of these fra ctions for dyeing is described, The dyeing properties of the fractions were compared with those of commercial trans-beta-carotene. Wash and light fastness of the dyed samples after the enzymatic pretreatment we re also studied. (C) 1997 Elsevier Science Ltd.
