The examined Alzheimer’s drugs are donepezil and rivastigmine. The used chemometric methods are partial least squares regression (PLS) and principal component regression (PCR). PLS and PCR were successfully applied for chemometric analysis of </span> <span lang="en-au" style="font-size:12pt;font-family:’Times New Roman’, serif;" xml:lang="en-au">metronidazole and moxifloxacin </span> <span lang="en-au" style="font-size:12pt;font-family:’Times New Roman’, serif;" xml:lang="en-au">in synthetic mixtures and pharmaceutical tablets.

The accuracy and precision of the developed method were validated by analyzing synthetic mixtures containing the examined drugs. As a result of the determination, high recoveries and low standard deviations were found. Absorbance and concentration values were used in Minitab and other chemometric programs to calculate estimated concentrations with PCR and PLS.  The second step, in drug tablets (Avelox and Flagy), was calculated amounts for </span> <span lang="en-au" style="font-size:12pt;font-family:’Times New Roman’, serif;" xml:lang="en-au">metronidazole and moxifloxacin </span> <span lang="en-au" style="font-size:12pt;font-family:’Times New Roman’, serif;" xml:lang="en-au">. </span>}, number={2}, publisher={Ağrı İbrahim Çeçen University}
