Abstract

An eno dyestuff is obtained from grape husks by forming an extract, treating with an alkaline agent and a water-soluble inorganic salt and then separating the precipitated product containing the eno dyestuff. Specified alkaline agents are Na2CO3, NaOH, Ca(OH)2 or KOH. Specified water-soluble salts are NaCl, KCl and CaCl2. Examples are given in which extracts from grape husks are treated with (a) Na2CO3 and CaCl2, (b) Ca(OH)2 and NaCl, and (c) NaOH, Na2CO3 and CaCl2.
