Natural aspirin of some members of the Rosaceae and Salicaceae families

White willow Salix alba L., a member of the family Salicaceae is characterized by presence phenolic compounds and their glycosides (1.5–11.0 %), such as salicin, salicortin, salireposide, picein, triandrin, syringin, tremulacin, flavonoids (1–4 %) namely luteolin, apigenin, quercetin, quercimeritrin, cosmosin, diosmetin, tannins (8–20 i.e. catechins, anthocyanidins, halotanines organic acids, ascorbic acid. Preparations white bark are used an antipyretic, anti-inflammatory, diaphoretic, analgesic, diuretic, astringent. The rhizomes with roots commonly known dropwort or fern-leaf Filipendula vulgaris Moench., Rosaceae phenologicoside gaulterin, hydrolysis which produces salicylic aldehyde, (up to 33 flavonoids, acid, polysaccharides, starch. herbs flowers anti-rheumatic, vasodilator, gastric, antiulcer agents. aim work determine composition L. tincture, Salicaceae, using gas-liquid chromatography (GLC) HPLC tincture root Moench. Rosaceae. Materials methods. Raw materials (underground organs) were harvested in July 2020 at ZSMU research site. Tinctures prepared according production recipe (1:5) (extractant was 70 % ethanol), investigated gas chromatograph Agilent 7890B mass spectrometric detector 5977B. spectra library NIST 14 identify components. (70 ethyl alcohol extractant) content acid derivatives. study performed (high-performance liquid chromatography) MS. Results. Qualitative quantitative analysis components chromatography, 39 different classes biologically active have been identified, among 10 predominated content. main one Salicin (39.53 %). GC roots, identified 34 groups compounds, dominated 11 components, Ethyl.alpha.-d-glucopyranoside (34.55 confirmed (flavonoids quercetin) derivatives (glycoside salicin) (Salix L.). Conclusions. By predominated, apigenin MS
