| Summary: | Drug delivery is one of the major applications in the biodegradable polymer science.
Chitosan is a non-toxic and naturally biodegradable polymer. It is soluble in acidic aqueous
media and insoluble in higher pH media. Chitosan has been modified to improve its properties
such as stability and the modified derivatives have been widely used in many applications
especially for drug delivery. There are several kinds of chitosan modification. This study
investigated the modification of chitosan with polyester-types of polymer and the fatty acidbased polymer. The aim of this study is to compare the formation encapsulation of chitosan-oleic
acid conjugate (Ch-OA) and chitosan- polycaprolactone (PCL) copolymer for the encapsulation
of Acalypha indica active compounds for drug delivery by using emulsion-solvent evaporation
technique. The crude extracts have been extracted and the phytochemicals inside the crude
extracts are less stable in nature. These active compounds need to be encapsulated to stabilize
them and delivered well into the body system. As for conclusion, chitosan:PCL is able to form
better encapsulation using this method. |
