Evaluation of some Turkish ce:italic>Salvia/ce:italic> species by principal component analysis based on their vitamin B2, mineral composition, and antioxidant properties

摘要

In this study, 14 TurkishSalviaspecies, 12 of which are endemic, were characterized based on their vitamin B2, mineral, total phenolic contents, and antioxidant activities. Determination of vitamin B2 inSalviaspecies was achieved by a fast and sensitive capillary electrophoresis technique using a laser induced fluorescence (LIF) detector. All samples contain vitamin B2 ranging from 0.165 to 1.19 mg/100?g. Fifteen elements (Ca, K, Na, Mg, Fe, Mn, Zn, Li, Cu, Co, Al, V, Sr, Sn, and Ni) were determined in eachSalviasample by inductively coupled plasma-mass spectrometry (ICP-MS). Total phenolic contents of theSalviasamples, ranging from 11.8 to 119?mg gallic acid equivalents (GAE)/g, were determined using the Folin-Ciocalteu's method. The antioxidant activities were evaluated by 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activity and ferric reducing antioxidant power assay (FRAP). Analysis data were evaluated by principal component analysis (PCA) and differentiation amongSalviaspecies was shown.
