Abstract: The invention provided herein a pharmaceutical process used for an extraction of proteins from pancreatic sample and estimation of the extracted proteins. Moreover, the invention provides a use of suitable is selected from citrate-phosphate buffer and bicarbonate buffer capable to extract proteins from pancreatic sample. The invention further provides an analytical method to perform estimation of extracted proteins. This process provides an improved extraction method to quantify protein present in the pancreatic sample.

Abstract: The present invention provides an improved method for analysis of pancreatic protein mixture comprises at least more than one biological active protein selected from amylase, protease and lipase, wherein the analysis and quantification of pancreatic protein mixtures is performed with Size Exclusion High Performance Liquid Chromatography (SE-HPLC). Also, the present invention provides the process for the separation, analysis and quantification of low molecular weight and high molecular weight enzymes present in pancreatic protein mixture.
