The aim of this work is to establish simple economical, and rapid spectrophotometric and chromatographic identification method for qualification of captopril in Active Pharmaceutical Ingredient. The work was carried out to for estimation of captopril in bulk pharmaceutical from by utilizing area under curve (AUC)method using UV –Visible Spectrophotometry .For this purpose the wavelength range 200-400 nm was selected. Thin-Layer chromatography (TLC) is a chromatography used to separate non-volatile mixtures. TLC can be used for monitoring the progress of a reaction ,identification compounds present in a given mixture, and determination of active pharmaceutical ingredient .TLC analysis of captopril in pharmaceutical and for using this method of analysis in future for the development of bio analytical method .for TLC the mobile phase with different concentration was used .we have established that the most perfect RF observed using mobile phase .chloroform –methanol are used (9:1)and (8:2) ratio .the development method was found to be simple ,linear ,precise ,accurate and sensitive which can be used for routine analysis for spectrophotometric and Thin-layer chromatographic method estimation of active pharmaceutical Ingredient.

Adult mammals undergo minimal regeneration having cardiac injury or ongoing burden of heart failure. Recent studies have established the importance of several evolutionary conserved mechanism of heart renovation by cyclic division of differentiated cardiomyocyte, cardiomyocyte proliferation, angiogenesis, extracellular matrix and heart regeneration, tissue engineering, transcription profile of cardiomyocytein development and regeneration, stem cell derived cardiomyocyte, and there transplantation. The c-kit-expressing cardiomyocyte stem cell also provide. The DNA translation is also occurs in regeneration process. In the review is part of special issue related to continuous renovation on cardiomyocyte and there related mechanism involved and gives future concept about novel biotechnology and tissue engineering.

The current work is carried out to for estimation of Chlorcyclizine Hydrochloridein bulk by utilizing area under curve (AUC) method using UV-Visible spectrophotometry. For this purpose the wavelength range 220-240nm was selected. Distilled water was used as a solvent throughout the work. Linearity was observed in concentration range 5-25µg/ml (R2=0.996) for the method. The present method was found to be simple & linear which can be used for routine quality control analysis for spectrophotometric estimation of Chlorcyclizine Hydrochloride in bulk.
