Для определения качественного и количественного состава основных компонентов настоя использовали обращенно-фазовую высокоэффективную жидкостную хроматографию на фазе Kromasil 100-5C4. Замена традиционно используемой для этого фазы С18 была связана с необходимостью исключить модифицирование привитой фазы β-циклодекстрином при работе с настоями, в которых хлорогеновые кислоты образуют комплексы типа «гость – хозяин» с β-циклодекстрином для снижения степени сорбции кофеина на бентонитовой глине. Направленный подбор основных модификаторов подвижной фазы позволяет управлять положением кофеина среди монокофеоилхинных кислот, а градиентный режим элюирования дает возможность детектировать кофеин, монокофеоилхинные и дикофеоилхинные кислоты одновременно. При использовании бентонитовой глины в Na+-форме удается удалить более 95% кофеина, но с потерей как монокофеоилхинных (порядка 25%), так и дикофеоилхинных (порядка 50%) кислот. Учитывая, что по литературным данным именно дикофеоилхинные кислоты образуют более устойчивые комплексы включения с β-циклодекстрином по сравнению с монокофеоилхинными кислотами, в напиток было предложено добавлять β-циклодекстрин. Отметим, что и подготовленные бентонитовые глины (как эффективные интеросорбенты) и β-циклодекстрин разрешены в использовании в пищевой и фармацевтической промышленности. В результате было установлено, что потери моно- и дикофеоилхинных кислот удается снизить более чем в 2 раза.</p></abstract><trans-abstract xml:lang="en"><p>This study examines a method for decaffeinating mate tea, an infusion made from Ilex paraguariensis leaves. A popular beverage in South America, mate is now available on the Russian market. Reversed-phase high-performance liquid chromatography on a Kromasil 100-5C4 phase was used to analyze the major components of the infusion. The conventional C18 phase was replaced to prevent modification by β-cyclodextrin, as chlorogenic acids in the infusion form host–guest complexes with it, thereby reducing caffeine adsorption on bentonite clay. The targeted adjustment of key mobile phase modifiers controlled the elution position of caffeine relative to monocaffeoylquinic acids. A gradient elution mode enabled the simultaneous detection of caffeine, mono-, and dicaffeoylquinic acids. The use of Na+-form bentonite clay removed over 95% of the caffeine. However, this process incurred substantial losses of approximately 25% of monocaffeoylquinic and 50% of dicaffeoylquinic acids. Since dicaffeoylquinic acids form more stable inclusion complexes with β-cyclodextrin than their monocaffeoyl counterparts, the addition of β-cyclodextrin to the beverage was proposed. Both bentonite clay (an effective enterosorbent) and β-cyclodextrin are approved for food and pharmaceutical use. This approach reduced the losses of both mono- and dicaffeoylquinic acids by more than half.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>напиток мате</kwd><kwd>декофеинизация</kwd><kwd>сорбция на бентонитовой глине</kwd><kwd>комплексы включения в β-циклодекстрин</kwd><kwd>обращенно-фазовая высокоэффективная жидкостная хроматография</kwd><kwd>С4-фаза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mate beverage</kwd><kwd>decaffeination</kwd><kwd>sorption on bentonite clay</kwd><kwd>inclusion complexes with β-cyclodextrin</kwd><kwd>reversed-phase high-performance liquid chromatography</kwd><kwd>C4 phase</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">Peres R.G., Tonin F.G., Tavares M.F.M., Rodriguez-Amaya D.B.
