Sorbus domestіca, Sorbus graeca, phenolic compounds, hydroxycinnamic acids, flavonoids.Abstract
Introduction. Sorbus domestіca and Sorbus graeca from the Rosaceae family are cultivated in Ukraine in gardens and parks. Their chemical composition is investigated insufficiently.
The aim of the study – to research the composition and the content of phenolic compounds of leaves of Sorbus domestіca and Sorbus graeca.
Research Methods. The content of phenolic compounds in leaves of Sorbus domestіca and Sorbus graeca was carried out by the high performance liquid chromatography method on Agilent Technologies chromatograph.
Results and Discussion. In leaves of Sorbus domestіca chlorogenic acid, rutin, quercetin-3-O-glucoside and quercetin were identified; in leaves of Sorbus graeca chlorogenic and neochlorogenic acids, rutin and 4'-methoxyquercetin-3-O-sophoroside were identified. The content of hydroxycinnamic acids in leaves of Sorbus domestіca is 389 mg/100 g, in leaves of Sorbus graeca – 147 mg/100 g (in terms of chlorogenic acid). The content of flavonoids in leaves of Sorbus domestіca is 1888 mg/100 g, in leaves of Sorbus graeca – 727 mg/100 g (in terms of rutin).
Conclusions. The composition and the content of phenolic compounds of Sorbus domestіca and Sorbus graeca were studied by the HPLC method. Leaves of Sorbus domestіca are more perspective for further pharmacological studies.
