Phenolic compounds of leaves of Sorbus domestіca and Sorbus graeca
2018
Introduction. Sorbus domest і ca 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 domest і ca and Sorbus graeca . Research Methods. The content of phenolic compounds in leaves of Sorbus domest і ca and Sorbus graeca was carried out by the high performance liquid chromatography method on Agilent Technologies chromatograph. Results and Discussion. In leaves of Sorbus domest і ca 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 domest і ca 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 domest і ca is 1888 mg/100 g, in leaves of Sorbus graeca – 727 mg/100 g (in terms of rutin). Conclusion s . The composition and the content of phenolic compounds of Sorbus domest і ca and Sorbus graeca were studied by the HPLC method. Leaves of Sorbus domest і ca are more perspective for further pharmacological studies.
