Antioxidant, Antimicrobial Activities and Fatty Acid Compositions of Wild spp. by Different Techniques Combined with Chemometrics (PCA and HCA).

Interest in medicinal plants and fruits has increased in recent years due to people beginning to consume natural foods. This study aims to investigate the total phenolic flavonoid content, antioxidant activity, condensed tannin content, oil content, and fatty acid compositions of five local breeds of spp. from Bayburt, Turkey, and their antioxidant and antimicrobial activities. The fatty acid composition of samples was performed with gas chromatography-mass spectrometry (GC-MS), and the total fatty acid content of samples was between 6.12% and 8.60%. The main fatty acids in spp. samples were α-linolenic acid (32.85-37.88%) and linoleic acid (30.98-34.28%) followed by oleic acid (12.85-19.56%). Two antioxidant assays produced similar results, demonstrating that extracts of wild L. had the highest ferric reducing antioxidant power (FRAP) (621.02 μmol FeSO.7HO/g) and 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) (0.10 SC mg/mL) values. According to principal component analysis (PCA), four components were determined. In addition, two main groups were determined according to hierarchical cluster analysis (HCA), and wild and culture of L. were in different subgroups. This is the first original report about the fatty acid composition and oil content of spp. grown in Bayburt, Turkey. The obtained results indicate that Bunge and , which have especially remarkable fatty acid content, antioxidant, and antimicrobial activity, could be potential sources for these properties in different areas of use.
