文摘
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. 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 of 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.
