چکیده (انگلیسی):

A Fourier transform infrared (FT-IR) spectrometric method was developed for the
rapid, direct measurement of diosmin in different pharmaceutical drugs. Conventional KBr-spectra
were compared for best determination of active substance in commercial preparations. The Beer–
Lambert law and two chemometric approaches, partial least squares (PLS) and principal component
regression (PCR+) methods, were tried in data processing.
