В составе лекарственных средств ретинол анализируется преимущественно методом высокоэффективной жидкостной хроматографии (ВЭЖХ) с предварительной очисткой и выделением витамина методом жидкостной экстракции. Однако в научной литературе встречаются и другие способы подготовки пробы и анализа этих соединений. Важным аспектом является также разделение витамина А с другими жирорастворимыми витаминами, которые наряду с витамином А входят в состав поливитаминных препаратов. Цель работы - анализ и обобщение данных литературы о современных методах определения витамина А и его производных в лекарственных препаратах. Проведен анализ номенклатуры препаратов, содержащих витамин А и зарегистрированных в Российской Федерации, а также методов анализа, используемых согласно нормативной документации производителей этих препаратов. Показано, что наиболее распространенным методом анализа эфиров ретинола является ВЭЖХ в изократическом режиме элюирования на октадецилсилильных сорбентах в обращенно-фазовом режиме, реже на аминопропилсилильных сорбентах в нормально-фазовом режиме элюирования. Бетакаротен в лекарственных средствах определяется преимущественно методом спектрофотометрии.</p></abstract><trans-abstract xml:lang="en"><p>Vitamin A is present in multivitamin products mainly in the form of retinol esters: retinyl acetate, retinyl palmitate, and beta carotene—retinol precursor (dimer) found in plants, which is capable of converting into retinol in liver cells. Retinol is determined in medicinal products primarily by high performance liquid chromatography (HPLC), with preliminary purification and vitamin isolation by liquid-liquid extraction. However, scientific literature also describes other methods of sample preparation and analysis of such compounds. An important issue is differentiation of vitamin A from other fat-soluble vitamins often included as components in multivitamin products. The aim of the study was to analyse and summarise data on current methods used for determination of vitamin A and its derivatives in medicinal products. The authors analysed the range of vitamin A products authorised in the Russian Federation, and the test methods described in their product specification files. The study demonstrated that the test method most often used for determination of retinol esters was HPLC with isocratic elution mode using octadecylsilyl packing in the reverse-phase mode, and, less frequently, aminopropylsilyl packing in the normal phase mode. Determination of beta carotene in medicinal products is most often performed using spectrophotometry. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>ВЭЖХ</kwd><kwd>ретинол</kwd><kwd>бетакаротен</kwd><kwd>ретинола ацетат</kwd><kwd>ретинола пальмитат</kwd><kwd>лекарственные формы</kwd><kwd>нормативная документация производителей лекарственных средств</kwd></kwd-group><kwd-group xml:lang="en"><kwd>HPLC</kwd><kwd>retinol</kwd><kwd>beta carotene</kwd><kwd>retinyl acetate</kwd><kwd>retinyl palmitate</kwd><kwd>dosage forms</kwd><kwd>product specification files</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания ФГБУ «НЦЭСМП» Минздрава России № 056-00005-21-00 на проведение прикладных научных исследований (номер государственного учета НИР 121021800098-4).</funding-statement><funding-statement xml:lang="en">The study reported in this publication was carried out as part of a publicly funded research project No. 056-00005-21-00 and was supported by the Scientific Centre for Expert Evaluation of Medicinal Products (R&amp;D public accounting No. 121021800098-4).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Rucker RB, Suttie JW, McCormick DB, eds.
