Conteúdo: 	bstract: Samples of cotton parts are extracted with boiling water and analysed colorimetrically by auto-analyser using a modification of the Greiss-Ilosvay reaction. Incorporation of a dialyser enables the method to be extended to a range of plant material including highly coloured tissue such as extracts of beetroot tuber. The method overcomes interferences due to potassium, sulphur, chloride and eliminates problems associated with precipitation of hydroxides. The procedure is sensitive, precise, and suitable to rapid analysis of large numbers of samples.
