Volatile compounds and antioxidant activity of Rosa canina L., biotypes from spontaneous flora of Albania

Abstract

It is reported that the Rosa canina L. fruit, with its high ascorbic acid, phenolics and flavonoids contents, have antioxidant, antimutagenic and anticarcinogenic effects. The aim of this study was to evaluate the content of polyphenols, vitamin C and antimicrobial and anti-inflammatory compounds. Volatile compounds of wild rose fruit were extracted by the SCFE-CO2 following the method (ISO121.2007E). The composition of the botanical extract was analyzed with 436-GC FID detector (Scion Instrument) in accordance with the standard (ISO 1124/1; 1124/2). The main groups of organic compounds identified by GC in the samples taken for analysis were Alkanes/Alkenes (76.5% ± 2.4), Alcohols (10.6% ± 2), Monoterpene (6.3% ± 1.3), Sesquiterpene/ oxygenated sesquiterpene (1.47% ± 0.6), Eugenol (5.03% ± 0.28). The content of polyphenols varies from 53-248 mg GAE / 100 gr per sample, the content of vitamin C from 545-1756 mg. Ascorbic acid/100 gr of sample. Most of the potential of medicinal plants in Albania are found as a part of spontaneous flora, which makes the quality of medicinal or aromatic plat values they contain to be higher compared to other areas in the region.
