The study aimed to examine the potential use of ethanol extracts of four medicinal plants to prevent and treat gout disease.Methods. An investigation of some typical compound contents such as polyphenols, flavonoids, and tannins in terms of two bioactive abilities, including anti-xanthine oxidase and antioxidant was carried out in Eclipta prostrata L., Artemisia vulgaris L., Apium graveolens L., and Piper betle L samples. Subsequently, the weight ratios of Piper betle L. and Artemisia vulgaris L. were investigated to reduce the total tannin content and get the most suitable anti-xanthine oxidase activity.Results. As well as having the highest target compound contents, Piper betle L. demonstrated the best anti-xanthine oxidase and antioxidant abilities even while its IC50 values were lower than positive control; however, its high total tannin content can cause some side effects. A mixture with a weight ratio of 1:1 of Piper betle L. and Artemisia vulgaris L. had a total tannin content half that of Piper betle L. as well as demonstrating potential anti-xanthine oxidase and antioxidant activities when IC50 was about 3.94 and 20.85 µg/mL, respectively.Conclusions. Out of the four selected plants, Piper betle L. demonstrated the best potential material for preventing and treating gout disease. However, due to the high tannin content in it, a mix of Piper betle L. and Artemisia vulgaris L. at a weight ratio of 1:1 gave optimal results for application in treatment.</p></abstract><trans-abstract xml:lang="ru"><p>Цели. Изучить потенциальное использование этанольных экстрактов четырех лекарственных растений для профилактики и лечения подагры.Методы. Образцы эклипты простёртой (Eclipta prostrata L.), полыни обыкновенной (Artemisia vulgaris L.), сельдерея пахучего (Apium graveolens L.) и перца бетель (Piper betle L. ) исследовались с точки зрения содержания в них полифенолов, флавоноидов и дубильных веществ, а также наличия биологически активных свойств, включая антиксантиноксидазную и антиоксидантную активность. Далее были найдены весовые соотношения Piper betle L. и Artemisia vulgaris L., позволяющие снизить общее содержание танина и получить наиболее подходящую антиксантиноксидазную активность.Результаты. Помимо самого высокого содержания целевого соединения, Piper betle L. продемонстрировал наилучшие антиксантиноксидазные и антиоксидантные свойства, даже несмотря на то, что его значения IC50 были ниже положительного контроля. Однако высокое содержание общего танина в нем может вызывать некоторые побочные эффекты. Смесь Piper betle L. и Artemisia vulgaris L. с массовым соотношением 1:1 имела общее содержание танина вдвое меньше, чем Piper betle L., а также демонстрировала потенциальную антиксантиноксидазную и антиоксидантную активность, при этом IC50 составлял около 3.94 и 20.85 мкг/мл соответственно.Выводы. Из четырех отобранных растений Piper betle L. является наилучшим потенциальным материалом для профилактики и лечения подагры. Однако из-за высокого содержания в нем танина смесь Piper betle L. и Artemisia vulgaris L. в соотношении по массе 1:1 дала оптимальные результаты для применения в лечении.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь подагра</kwd><kwd>ингибиторы ксантиноксидазы</kwd><kwd>дубильные вещества</kwd><kwd>Piper betle L.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gout disease</kwd><kwd>xanthine oxidase inhibitors</kwd><kwd>tannins</kwd><kwd>Piper betle L.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Мы выражаем признательность за время и средства, предоставленные Технологическим университетом Хошимина (HCMUT) и Вьетнамским национальным университетом Хошимина (VNU-HCM) для этого исследования.</funding-statement><funding-statement xml:lang="en">We acknowledge the support of time and facilities from Ho Chi Minh City University of Technology (HCMUT), VNU-HCM, for this study.</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">Collaborators G.O.D., Bernabe E., Marcenes W., Hernandez C.R., et al.
