Гиперицин представлен единственным хроматографическим пиком с временем удержания 23.10 мин, имеющим в масс-спектре характерный сигнал молекулярного иона [M - H+]- с m/z 504.05. В электронных спектрах поглощения настойки “Диагиперон” и экстракта травы зверобоя продырявленного Hypericum perforatum в метаноле помимо характерных для гиперицина полос при 550 и 590 нм наблюдается полоса поглощения при 665 нм, обусловленная наличием хлорофилла. Показано, что при возбуждении гиперицина (λвозб = 470 нм) в спектре испускания настойки “Диагиперон” присутствуют характерные для гиперицина полосы при 593 и 640 нм, а в спектре испускания экстракта травы зверобоя продырявленного в метаноле кроме полос испускания гиперицина наблюдается незначительная по интенсивности полоса испускания хлорофилла при 670 нм. Установлено, что спектрофотометрическое и спектрофлуориметриче-ское определение гиперицина в настойке “Диагиперон” и в траве зверобоя продырявленного дает схожие результаты, которые соответствуют нормированному содержанию гиперицина в исследуемых образцах.</p></abstract><trans-abstract xml:lang="en"><p>For use as a standard sample, hypericin was isolated from the “Diahyperon” tincture. The chromatographic purity of the hypericin sample was confirmed by high-performance liquid chromatography/mass spectrometry. Hypericin is represented by a single chromatographic peak with a retention time of 23.10 min, which has a characteristic signal of the molecular ion [M - H+] - with m/z 504.05 in the mass spectrum. In addition to the band characteristic of hypericin at 550 and 590 nm, the electronic absorption spectra of the “Diahyperon” tincture and a methanolic extract of Hyperici herba (Hypericum perforatum) show an absorption band at 665 nm due to the presence of chlorophyll. It was shown that upon excitation of hypericin (λex = 470 nm), the emission spectrum of the “Diahyperon” tincture contains bands characteristic of hypericin at 593 and 640 nm. In addition to the hypericin emission bands, the emission spectrum of the methanolic extract of Hyperici herba demonstartes a low intensity chlorophyll emission band at 670 nm. It was found that the spectrophotometric and spectrofluorimetric determination of hypericin in “Diahyperon” tincture and in Hyperici herba gives convergent results, which are consistent with the standardized values of the hypericin content in the studied samples.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гиперицин</kwd><kwd>трава зверобоя продырявленного</kwd><kwd>электронная спектроскопия</kwd><kwd>флуоресцентная спектроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypericin</kwd><kwd>Hyperici herba</kwd><kwd>electron spectroscopy</kwd><kwd>fluorescence spectroscopy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках задания “Разработать методику спектрофлуориметрического определения гиперицина в лекарственных средствах” подпрограммы “Фармакология и фармация” Государственной программы научных исследований “Химические технологии и материалы” на 2016—2020 гг.
