Physicochemical properties were determined using the following methods: phenol-sulfuric acid test [13], a-naphthol reaction [14], iodination reaction [15], Fehling's test [16], carbazole reaction [17], Fe[Cl.sub.3] reaction [18], and Coomassie brilliant blue reaction [19].
The results from the phenol-sulfuric acid test, a-naphthol reaction, iodination reaction, Fehling's test, carbazole reaction, Fe[Cl.sub.3] reaction, and Coomassie brilliant blue test were presented.
