Разработана и валидирована спектрофотометрическая методика оценки суммы тритерпеноидов и стероидов в экстрактах трутовиков, основанная на реакции Либермана—Бурхардта. Оптимальные условия проведения анализа: использование хлороформа в качестве экстрагента, соотношение экстракт:реактив 1:1, аналитическая длина волны 665 нм, время реакции 90 мин. Методика показала удовлетворительные характеристики специфичности, правильности (восстановление 100.6—108.6 %), прецизионности (RSD ≤ 3.4 %) и линейности в диапазоне 31.25—1000 мкг/мл (R2 &gt; 0.99). Полученные данные подтверждают возможность применения разработанного подхода для стандартизации грибного сырья и контроля качества продуктов на его основе.</p></abstract><trans-abstract xml:lang="en"><p>Polypore fungi represent a promising source of biologically active triterpenoid and steroid compounds; however, their quantitative determination is complicated by the lack of reference standards as well as the variety and structural similarity of the compounds. In this study, a spectrophotometric method based on the Liebermann–Burchard reaction was developed and validated for the determination of total triterpenes and steroids in polypore extracts. The optimal analytical conditions were established as follows: chloroform as the extraction solvent, extract-to-reagent ratio of 1:1, analytical wavelength of 665 nm, and reaction time of 90 minutes. The method demonstrated satisfactory specificity, accuracy (recoveries of 100.6–108.6%), precision (RSD ≤ 3.4%), and linearity in the range of 31.25–1000 μg/mL (R2 &gt; 0.99). The obtained results confirm the applicability of the proposed approach for the standardization of fungal raw materials and the quality control of polypore-based products.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>трутовые грибы</kwd><kwd>тритерпеноиды</kwd><kwd>стероиды</kwd><kwd>спектрофотометрия</kwd><kwd>реакция Либермана—Бурхардта</kwd><kwd>валидация методик</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polypore fungi</kwd><kwd>triterpenoids</kwd><kwd>steroids</kwd><kwd>spectrophotometry</kwd><kwd>Liebermann–Burchard reaction</kwd><kwd>method validation</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">U.
