Colorimetric Method for Determination of Sugars and Related Substances
TL;DR: In this article, a method was developed to determine submicro amounts of sugars and related substances using a phenol-sulfuric acid reaction, which is useful for the determination of the composition of polysaccharides and their methyl derivatives.
Journal ArticleDOI
New method for quantitative determination of uronic acids
TL;DR: A new method for determination of uronic acids with meta-hydroxydiphenyl is introduced, which is simpler, quicker, more sensitive, and more specific than other methods, and it needs lesser amounts of fluid.
