The instrumental development and analytical applications of UV regions absorption spectrophotometry produced in the last 10 y (since 2006) are reviewed. The methods were classified according to the spectra data used, including zero order absorption, derivative and ratio amplitudes. The proposed methods were applied to solve different complex pharmaceutical mixtures and the obtained results were accepted when compared to other reported methods. � 2016 The Authors.EnglishAbsorptivityAmplitudeDifferentialRatio spectraSpectral ManipulationSuccessivehumanultraviolet spectrophotometryReviewhttps://doi.org/10.22159/ijpps.2016v8i10.13537PubMed ID :
