Study of the component composition of essential oils of pentaphylloides Fruticosa (L.) О. Schwarz (Dasiphora fruticosa (L.) Rybd.) raw materials

Pentaphylloides fruticosa (L.) О. Schwarz (Dasiphora fruticosa (L.) Rybd.) is one of the most common species in Eurasia. There are about 150 known varieties of Pentaphylloides fruticosa, which are used as an ornamental plant. The content of tannins, polyphenols, flavonoids, and macro- and microelements was detected and determined in the above-ground part of some varieties of Pentaphylloides fruticosa. Studies on the content and composition of essential oils have not been conducted. The aim. The aim of the work was to study the quantitative composition and identification of components of essential oil from raw materials Pentaphylloides fruticosa. Materials and methods. Hydrodistillates obtained from dried raw materials of Pentaphylloides fruticosa, collected from different growing sites in Ivano-Frankivsk and Vinnytsia regions (Ukraine), were analyzed by gas chromatography-mass spectrometry. Research results. Up to 91 essential oil components were identified and quantified in the studied raw materials. The content of essential oils was from 0.52 to 3.11 mL/kg, depending on the type of raw material. The predominant essential oil compounds in the raw material of Pentaphylloides fruticosa were linalool, geraniol, (E)-β-damascenone, (E)-geranylacetone, (E)-β-ionone, L-β-elemene, germacrene D, hexahydrofarnesyl acetone, phytol, benzyl benzoate. The largest amount of essential oil components was found in shoots with yellow flowers of Pentaphylloides fruticosa. The results of the study revealed strong positive correlation links (> 0.9) between such pairs of compounds as L-carvone and hexahydrofarnesyl acetone, benzyl benzoate and 1,2-diphenoxyethane; L-β-pinene and α-muurolene, L-β-pinene and hexahydrofarnesyl acetone; L-bornyl acetate and L-β-elemene, L-bornyl acetate and benzyl benzoate, L-bornyl and 1,2-diphenoxyethane, D-limonene and eucalyptol, L-β-pinene and L-carvone. Conclusions. In connection with the obtained research results and the identification of such compounds as linalool, geraniol, (E)-β-damascenone, (E)-geranylacetone, (E)-β-ionone, germacrene D, phytol, benzyl benzoate, it is advisable to further study the species Pentaphylloides fruticosa, its pharmacological activity and possibilities for further application in medicine
