Для определения куркуминоидов используются как современные, так и классические методы анализа. Однако проблема анализа куркуминоидов в составе растительных и лекарственных объектов остается актуальной. Метод анализа куркуминоидов должен быть экономически доступным, но в то же время обеспечивать разделение компонентов для возможности их идентификации и количественной оценки. В настоящей работе в качестве такого метода использован капиллярный электрофорез (HPCE) в варианте мицеллярной электрокинетической хроматографии с диодно-матричным детектированием (MEKC/DAD).</p></sec><sec><title>Цель</title><p>Цель. Целью настоящего анализа является выбор оптимальных условий разделения куркуминоидов с использованием капиллярного электрофореза в варианте мицеллярной электрокинетической хроматографии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Разделение куркуминоидов проводили на приборе для капиллярного электрофореза – Agilent 7100 CE с диодно-матричным детектором и системой контроля и сбора данных Agilent ChemStation. В качестве электролита использован боратный буфер (20 мМ, рН 9,3) с добавкой додецилсульфата натрия – SDS (30 мМ) в соотношениях 1 : 1. Ввод пробы осуществлялся гидродинамическим способом – 50 мБар/3 сек, напряжение на электроде – +25 кВ, капилляр кварцевый – Lэфф./Lобщ. = 30/40 см, ID = 50 µm, температура капилляра – +20 °С. Выход куркуминоидов контролировали при длине волны диодно-матричного детектора – λmax = 425 нм/4 нм, реферируемая длина волны 360 нм/100 нм.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Куркуминоиды в боратном буферном растворе с добавкой SDS практически не разделяются, что связано с высокой активностью электроосмотического потока, для подавления которого добавлялся спирт этиловый 95%-й. В ходе исследований установлено, что добавка спирта этилового в количестве 20 % по отношению к буферному раствору позволяет разделять смесь куркуминоидов.</p></sec><sec><title>Заключение</title><p>Заключение. Таким образом, подобраны условия для разделения суммы куркуминоидов методом HPCE в варианте мицеллярной электрокинетической хроматографии (MEKC). Установлено, что для разделения куркуминоидов данным методом необходимо использование электролита, состоящего из смеси равных объемов боратного буфера (20 mM) и додецилсульфата натрия (30 mM) и спирта этилового в количестве 20 % от объема электролита. Дальнейшее увеличение концентрации спирта этилового в электролите нецелесообразно, поскольку может отрицательно влиять на стабильность мицелл.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Curcuminoids are natural polyphenolic colorants with a wide spectrum of pharmacological activity. Modern hybrid and classical methods are used for the determination of curcuminoids. However, the problem of the analysis of curcuminoids in the composition of plant and medicinal objects remains relevant. In this work, capillary electrophoresis (HPCE) in the variant of micellar electrokinetic chromatography with diode array detection (MEKC/DAD) was used as such a method.</p></sec><sec><title>Aim</title><p>Aim. The purpose of this analysis is the choice of optimal conditions for the separation of curcuminoids using capillary electrophoresis in the form of micellar electrokinetic chromatography.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Separation of curcuminoids was carried out on an Agilent 7100 CE capillary electrophoresis instrument with a diode array detector and an Agilent Chem Station monitoring and data acquisition system. Borate buffer (20 mM, pH 9.3) with the addition of sodium dodecyl sulfate – SDS (30 mM) in ratios of 1 : 1 was used like the electrolyte. The sample was injected hydrodynamically – 50 mbar/3 sec, electrode voltage is +25 kV, quartz capillary – total capillary length/effective capillary length = 30/40 cm, ID = 50 µm, capillary temperature +20 °С. The output of curcuminoids was monitored at the wavelength of the diode-matrix detector – λmax = 425 nm/4 nm, the refereed wavelength is 360 nm/100 nm.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Curcuminoids in a borate buffer solution with the addition of SDS are practically not separated, which is associated with a high activity of the electroosmotic flow, to suppress which 95 % ethyl alcohol was added. In the course of research, it was found that the addition of ethyl alcohol in an amount of 20 % relative to the buffer solution makes it possible to separate the mixture of curcuminoids.</p></sec><sec><title>Conclusion</title><p>Conclusion. Thus, the conditions for the separation of the total curcuminoids by the HPCE method in the variant of micellar electrokinetic chromatography (MEKC) were selected. It has been established that for the separation of curcuminoids by this method, it is necessary to use an electrolyte consisting of a mixture of equal volumes of borate buffer (20 mM) and sodium dodecisulfate (30 mM) and ethyl alcohol in an amount of 20 % of the electrolyte volume. A further increase in the concentration of ethyl alcohol in the electrolyte is unreasonable, since it can adversely affect the stability of micelles.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>куркуминоиды</kwd><kwd>капиллярный электрофорез</kwd><kwd>мицеллярная электрокинетическая хроматография</kwd><kwd>диодно-матричный детектор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>curcuminoids</kwd><kwd>capillary electrophoresis</kwd><kwd>micellar electrokinetic chromatography</kwd><kwd>diode-matrix detector</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ashraf K., Sultan S.
