The anthrone method was used for the quantification of the carbohydrate content of EPS [35]. In brief, 160 µL of anthrone reagent (0.125% anthrone [wt/vol] in 94.5% [vol/vol] H 2 SO 4 ) was mixed .
4. Estimation of total carbohydrate - Introduction The total saccharides moiety in a sample can be estimated by the anthrone method which is a simple colorimetric method. The first step in total carbohydrates measurement is to hydrolyze the polysaccharides and to dehydrate the monomers. When anthrone it reacts with monomers to give colored .

The carbohydrate is estimated using the anthrone method Among many colorimetric methods for carbohydrate determination, the anthrone–sulfuric acid [9] is one of the most commonly used techniques. This method has been used to measure the soluble sugars in samples of different vegetal tissues of apple trees [10], in maize plants [11] and spider hemolymph [12].
