Selected phenolic compounds in fruits of wild growing Cornus mas L.

The aim of the present study was to determine the content of six phenolic compounds, natural anti-oxidants, in fruits of wild growing Cornus mas L. Fruits were sampled from two different locations. The extracts were obtained from fresh fruits and subjected to LC-MS/MS analysis to identify and quantify the content of neochlorogenic acid and five derivatives of quercetin. All of the analyzed phenolic compounds were detected in total sample of C. mas fruits, and their occurrence and content were clearly locality-dependent. Out of analyzed compounds, the prevailing was neochlorogenic acid (5-O-CQ) in samples from Avala, whereas glucuronide (Q-3-O-GlcA) dominated in samples from Zlatar lake. These results showed that wild growing populations are rich source of natural antioxidants, especially those with proved pharmacological activity in humans, such as glucuronide. As indicated by data on traditional usages and ethnopharmacological knowledge, C. mas fruits collected in wild are valuable source of natural antioxidants and deserve attention in preservation of genetic and biological diversity
