A simple and rapid colorimetric method for separate quantitative analysis of KDO and 3,6-DDH in mixtures has been described. The method is based on periodate-TBA reaction with deoxy sugars before and after reduction with sodium borohydride. The absorbance of the color material was found to be a lin
