Abstract

A Fourier transform infrared (FT-IR) spectrometric method was developed for the rapid, direct measurement of dehydropeiandrosterone. Conventional KBr spectra and KBr + 2.0 mg microcrystalline cellulose (MCC) spectra were compared for best determination of active substance in drug formulation. Two chemometric approaches, partial least-squares (PLS) and principal component regression (PCR+) methods were used in data processing. The best results were obtained with PCR+ method.
