| Tartalmi kivonat: | In this work, a study on phytochemical profiles of comfrey (Symphytum officinale L.) root extract obtained by subcritical water extraction (SWE) has been carried out. Chemical composition was assessed by high-performance liquid chromatography coupled with electrospray time-of-flight mass spectrometry (HPLC-ESI-TOF-MS) identifying 22 compounds including organic acids, phenolic acids, flavonoids and fatty acids. Great number of phenolic acids and flavonoids were found in the extract obtained by SWE, with citric acid, caffeic acid and derivative, salvianolic acid B, hydroxybenzoic acid, syringetin-3-O-glucoside and quercetin 3-O-malonylglucoside as the most abundant compounds. Moreover, quercitin-3- malonylglucoside isomers, hydroxybenzoic acid glucoside, cirismaritin isomers, p-coumaric acid, hydroxycoumarin and methylcoumarin, among others, were identified for the first time in S. officinale root. Overall, the results indicate the potential of SWE for the production of highquality plant extracts from S. officinale root. |
