Extraction and Characterization of Phenolic Compounds from Rose Hip (Rosa canina L.) Using Liquid Chromatography Coupled with Electrospray Ionization - Mass Spectrometry

Wild berry are a rich of natural compounds which provide them high antioxidant potential. The compounds which provide them these proprieties are known CO be vitamins, flavonoids, anthocyanins and phenolic acids. The aim of this study was to extract, identify and characterize bioactive compounds from rose hip (Rosa canina L.) currently found in Romania. A qualitative high-performance liquid chromatography coupled with electrospray ionization mass spectrometric (ESI-MS) detection in positive ion mode has been used to identify phenolic compounds from rose hip crude extract. The chromatograms revealed the presence of a large number of compounds (19), identified and grouped as phenolic acids and flavones/ols, flavan-3-ols and also anthocyanins. Based on obtained results these berries can be highly recommended as part of our diet. Also this finding represents a contribution CO the chemical characterization of phenolic profile of rose hip.
