Characterization of gum was done by scanning electron microscopy-energy dispersivse X-ray and spectrophotometer infrared. Gum refluxed with HCl 2 N for 14 h would be the monomer. Galactose and mannose were used as standard. Purity test was done by the thin-layer chromatography (TLC) and <em>Luff Schoorl </em>method.</p><p><strong>Results: </strong>The study results obtained that the modification methods (4.8%) and centrifugation (4.6%). Identification of functional groups with the spectrophotometer infrared provided the same spectrum forms between the two methods. Purity test by TLC with the best eluen butanol: ethanol:water 2:2:2. <em>Luff Schoorl's </em>method gives results of 87.46%, whereas the raw comparison galactose-mannose standard 96.69%.</p><p><strong>Conclusions: </strong>The modification method gives more results with the same purity rate as the centrifugation method.</p> ER -
