Floral scents and metabolites from cut flowers of 14 peony cultivars (Paeonia lactiflora Pall.) were analyzed todiscriminate different cultivars and to compare the Korean cultivar with the other cut peonies imported to Korea usingelectronic nose (E-nose) and Fourier transform infrared (FT-IR) spectroscopy combined with multivariate analysis,respectively. Principal component analysis (PCA) and discriminant function analysis (DFA) dendrogram of peony floralscents were not precisely same but there were 3 groups including same cultivars. PCA and partial least squares-discriminantanalysis (PLS-DA) dendrograms of peony metabolites showed that different cut peony cultivars were clustered into twomajor groups including same cultivars. Fragrance pattern of Korean ‘Taebaek’ was classified to same group with ‘Jubilee’on the PCA and DFA results and its metabolite pattern was clearly discriminated by the PCA and PLS-DA compared to theother cultivars. These results show that the 14 peony cut flowers could be discriminated corresponding to their chemicalrelationship and the metabolic profile of Korean ‘Taebaek’ has distinctive characteristics. Furthermore, we suggest thatthese results could be used as the preliminary data for breeding new cut peony cultivars and for improving the availabilityof Korean cut peony in cosmetic industry.
