The double divisors used are normalized spectra of diphenhydramine /N-oxide degradate of diphenhydramine binary mixture for both paracetamol and p-aminophenol and paracetamol/p-aminophenol binary mixture for both diphenhydramine hydrochloride and its N-oxide degradate. The double divisors binary mixtures contain 40 μg/mL of each component. The selected wavelengths are 243-233 nm, 223.8-270.2 nm, 237-250 nm and 265-234.6 nm for the 4 compounds, respectively. Both methods were successfully applied for the quantification of the four components in labor
