ABSTRACT:
The prospects of natural polymers are brighter as synthetic polymers have certain disadvantages such as high cost, toxicity, environmental pollution during synthesis, non-renewable sources, side effects, less patient compliance, etc. Mucilages form slimy masses in water. Mucilages are typically heterogeneous in composition. Mucilages are polysaccharide complexes formed from sugar and uronic acid units. Mucilages form slimy masses in water, are typically heterogeneous in composition. The rhizomes of Eulophia herbacea contain a high proportion of mucilage and it also being used for different therapeutic purposes. However there are no reports on isolation and characterization of mucilage of Eulophia herbacea. Hence, the present study is planned to isolated and characterized for its morphological characteristics, identification by chemical tests, Solubility, melting range, pH, Swelling index, Ash values, presence of foreign organic matter, test for lead and arsenic, Loss on drying, Density, compressibility index and angle of repose etc. which will be standardizing parameter for future scientist.
