A DSC study of some biomaterials relevant to pharmaceutical industry

The present investigation concerns with thermal analysis of biomaterials such as Chitosan, Xanthan gum, Guar gum Pectin, Karaya gum, Sodium alginate, and Psyllium husk mucilage. The DSC curve of the natural polymers showed its specific endothermic peaks and Delta H (f) values, and these will be helpful in determining the fitness of the polymers with active drug. The drug and natural polymer compatibility study is now one of the recognized methods for preformulation step in pharmaceutical drug development. All the natural polymers showed endothermic peak below 150 A degrees C, and this make them suitable with a wide class of therapeutic drugs.
