Simultaneous Determination and Classification of Riboflavin, Thiamine, Nicotinamide and Pyridoxine in Pharmaceutical Formulations, by UV-Visible Spectrophotometry and Multivariate Analysis
Soft Independent Modeling of Class Analogy (SIMCA) e Regressão por Mínimos Quadrados Parciais foram usados nesse trabalho para a identificação e quantificação de tiamina, riboflavina, nicotinamida e piridoxina, por espectrofotometria UV-Vis, sem realizar os procedimentos analíticos de separação e pré-concentração. Para a quantificação, os intervalos de trabalho estabelecidos foram 1-14 mg L par...
متن کاملSimultaneous Determination of Losartan and Hydrochlorothiazide in Pharmaceutical Preparations by Derivative and Ratio Derivative Spectrophotometry
Background & Aims: Losartan is a non-peptide potent antihypertensive agent that acts through blocking angiotensin II receptors. Hyzaar® is a combination product that contains two drugs, losartan and hydrochlorothiazide, used to lower high blood pressure. There are some reports regarding simultaneous measurement of the drugs in pharmaceutical and biological samples which includes HPLC, CE, CEC, ...
متن کاملSimultaneous Determination of Potassium Clavulanate and Amoxicillin Trihydrate in Bulk, Pharmaceutical Formulations and in Human Urine Samples by UV Spectrophotometry
A simple and sensitive UV spectrophotometric method was developed and validated for the simultaneous determination of Potassium Clavulanate (PC) and Amoxicillin Trihydrate (AT) in bulk, pharmaceutical formulations and in human urine samples. The method was linear in the range of 0.2-8.5 μg/ml for PC and 6.4-33.6 μg/ml for AT. The absorbance was measured at 205 and 271 nm for PC and AT respectiv...
متن کاملSimultaneous spectrophotometric determination of Rifampicin, Isoniazid and Pyrazinamide in a single step
Three antituberculosis medications are investigated in this work consist of rifampicin, isoniazid and pyrazinamide. The ultra violet (UV) spectra of these compounds are overlapped, thus use of suitable chemometric methods are helpful for simultaneous spectrophotometric determination of them. A generalized version of net analyte signal standard addition method (GNASSAM) was used for determinatio...
