Объектами исследования являлись 5 образцов травы солодки голой, заготовленных в летний период времени в различных местах произрастания и культивирования. В качестве стандартного образца использовали пиностробин. Регистрацию УФ-спектров проводили с помощью спектрофотометра «Specord 40» (Analytik Jena AG, Германия) методом дифференциальной спектрофотометрии.

Количественное определение суммы флавоноидов в траве солодки голой проводили при аналитической длине волны 310 нм в пересчёте на пиноцембрин. Установлены оптимальные параметры экстрагирования суммы флавоноидов из травы солодки голой: экстрагент – спирт этиловый 90%; соотношение «сырье-экстрагент» – 1:50; время экстракции – 60 мин; степень измельчения сырья – 2 мм. Определено содержание суммы флавоноидов для травы солодки голой, которое варьирует от 0,39±0,002 до 3,41±0,015% с учётом влажности растительного сырья от 9,97±0,003 до 10,03±0,003% в зависимости от места произрастания, культивирования и года сбора растительного сырья. Погрешность единичного определения с доверительной вероятностью 95% составляла ±0,73.</p></sec><sec><title>Заключение</title><p>Заключение.

The subjects of research were 5 samples of licorice herb harvested in summer in various places of growing and cultivation. Pinostrobin was used as a standard sample. The registration of the electronic spectra was carried out with a spectrophotometer (Analytik Jena AG, Germany) by differential spectrophotometry, 96% ethanol was used as a solvent.</p></sec><sec><title>Results</title><p>Results. The methods for quantitative determination of total flavonoids in Glycyrrhiza glabra L. was carried out at an analytical wavelength of 310 nm equivalent to pinocembrin. The optimum parameters for the extraction of total flavonoids from Glycyrrhiza glabra L. were as follows: the extractant – 90% ethanol; the «raw material-extractant» ratio was 1:50; the extraction time was 60 min; the degree of atomization was 2 mm. The content of total flavonoids for the Glyccyrhiza glabra L. herb has been determined, it varies from 0.39±0.002 to 3.41±0.015% with the humidity of the vegetative raw material from 9.97±0.003 to 10.03±0.003% depending on the place of the vegetation, cultivation and year of the raw material collection. The error of the single determination with a 95% confidence level was ±0.73%.</p></sec><sec><title>Conclusion</title><p>Conclusion. The developed methods for the quantitative determination of total flavonoids in Glycyrrhiza glabra L. herbs can be used to solve the issues of standardization of these medicinal plant raw materials.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>солодка голая</kwd><kwd>Glycyrrhiza glabra L.</kwd><kwd>трава</kwd><kwd>флавоноиды</kwd><kwd>пиноцембрин</kwd><kwd>стандартизация</kwd><kwd>спектрофотометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>licorice</kwd><kwd>Glycyrrhiza glabra L.</kwd><kwd>herb</kwd><kwd>flavonoids</kwd><kwd>pinocembrin</kwd><kwd>standardization</kwd><kwd>spectrophotometry</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данное исследование не имело какой-либо финансовой поддержки от сторонних организаций.</funding-statement><funding-statement xml:lang="en">This study did not receive any financial support from outside organizations.</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">Егоров М.В., Куркин В.А., Запесочная Г.Г., Быков В.А.
