Felodipine is a vasoselective calcium channel antagonist of the dihydropyridine class used in the management of hypertension. It is chemically described as ethyl methyl 4-(2‚3-dichlorophenyl)-1‚4-dihydro-2‚6-dimetylpyridine-3‚5-di-carboxylate. Estimation of felodipine in biological samples and human plasma has been reported by gas chromatographic (GC) (Soons et al 1990) and liquid chromatographic (LC) methods. Estimation and separation of the metabolites of felodipine in biological samples have been

centrifugation. This will separate the protein crude from the liquid. (Campbell) After protein purification‚ the crude now undergoes characterization. Activity assay‚ Bradford assay‚ and Warburg-Christian method can be used to characterize proteins. Spectrophotometric analysis are usually used to determine some properties of the protein such as protein concentration. Results Discussion A. Invertase from yeast The prepared yeast is first washed with hexane to defat the protein. After it‚ the yeast
