High performance liquid chromatography (HPLC) and flow-injection mass spectrometric (FIMS) fingerprinting techniques were tested for their potential in differentiating organic and conventional peppermint samples. Ten organic and ten conventional peppermint samples were examined using HPLC-UV and FIMS methods. The principal component analysis (PCA) showed that both HPLC and FIMS fingerprints could determine the difference in the commercial organic and conventional peppermints. FIMS fingerprinting provided a rapid test to differentiate organic and conventional peppermints in 1 min analysis, and has potential for high-throughput applications. On the other hand, HPLC fingerprints provide more information about the chemical composition of the samples, but take a longer time to differentiate organic and conventional peppermint samples.
