Разработан метод УФ-видимой спектроскопии для одновременной оценки кверцетина и эллаговой кислоты в суспензии. Валидация метода проведена в соответствии с рекомендациями ICH Q2R2. Построены калибровочные кривые (R2>0.98), демонстрирующие линейный отклик для диапазонов концентраций обоих препаратов. Результаты показали высокий уровень точности и воспроизводимости (RSD% <2%). Данный метод можно внедрить в повседневные лабораторные условия, что облегчает одновременный мониторинг уровней препарата как в объемных, так и в лекарственных формах.

А UV visible spectroscopic method has been developed for the simultaneous estimation of quercetin and ellagic acid in a suspension. Validation of the developed method was done according to ICH Q2R2 guidelines. Calibration curves (R2>0.98) were prepared, demonstrating a linear response for the concentration ranges of both drugs. The results indicated high levels of accuracy and precision (all RSD% values <2%). The findings suggest that this method can be readily adopted in routine laboratory settings, facilitating the simultaneous monitoring of drug levels in both bulk and dosage forms.
