Aplicação de métodos de calibração multivariada para a determinação simultânea de riboflavina (VB2), tiamina (VB1), piridoxina (VB6) e nicotinamida (VPP) UV spectrophotrometry and chemometrics methods for simultaneous determinations of riboflavin (VB2), thiamine (VB1), pyridoxine (VB6) and nicotinamide (VPP)

Aplicação de métodos de calibração multivariada para a determinação simultânea de riboflavina (VB2), tiamina (VB1), piridoxina (VB6) e nicotinamida (VPP) UV spectrophotrometry and chemometrics methods for simultaneous determinations of riboflavin (VB2), thiamine (VB1), pyridoxine (VB6) and nicotinamide (VPP)

<abstract language="eng">In this work, the artificial neural networks (ANN) and partial least squares (PLS) regression were applied to UV spectral data for quantitative determination of thiamin hydrochloride (VB1), riboflavin phosphate (VB2), pyridoxine hydrochloride (VB6) and nicoti...
