Phenolic compounds in species of the genus Salvia L.

Introduction. Salvia oficinallis L. is a medicinal plant of the Lamiaceae family containing essential oils, flavonoids and tannins. S. oficinallis L. and S. sclarea L. are used in medicine because of their anti-inflammatory, antimicrobial properties. The aim of the work was to conduct comparative qualitative and quantitative analyses of phenolic compounds in the leaves and stems of some species of the genus Salvia L. Material and methods. The object of the study is the leaves and stems of some representatives of the genus Salvia L.: Salvia officinalis L., Salvia nemorosa L., Salvia dumetorum Andrz. ex Besser, Salvia verticillata L., Salvia nutans L. Qualitative determination of flavonoids was carried out by thin-layer chromatography. Quantitative determination of the amount of flavonoids in aqueous-alcoholic extracts from raw materials of some species of the genus Salvia was carried out by differential device in terms of the standard sample of cynaroside. Results and discussion. The diagnostic feature of shas been confirmed. medicinal by the presence of water-alcohol extracts from leaves and stems of apigenin and luteolin on chromatographic profiles. The content of rutin in the leaves and stems of medicinal plants is not undermined by TLC analysis, however, it was reliably detected on chromatographic profiles of S. dumetorum in its leaves and stems. Conclusion. The interspecific features of the spectra in the differential absorption curves make it possible to carry out chemical taxation of medicinal products, which increases the importance of spectrophotometry as a method of detecting authenticity for this type of medicinal plant raw materials
