What is Application and Exploration of Fast Gas Chromatography-surface Acoustic Wave Sensor to the Analysis of Thymus Species about?

species Fragrance pattern analysis Discrimination Headspace solid-phase microextraction (HS-SPME) gas chromatography-mass spectrometry (GC-MS) Pharmacologically active species (thymol) a b s t r a c t Fast gas chromatography combined with surface acoustic wave sensor (GC/SAW) has been applied for the detection of volatile aroma compounds emanated from thymus medicinal plants such as T. quinquecostotus (Jeju and Mt. Gaya in South Korea), T. quinquecostotus var. japonica (Ulreung island in South Korea), T. mongolicus (Northeastern Asia), and T. serpyllum (Europe). The GC/SAW involving the fragrance pattern analysis provides a novel analytical method with a very fast separation and characterization of aromas caused by the delicate difference of chemical composition according to botanical and geographical origin. On the comparison of experiments, the characteristic components and analytical tendency for air-dried thymus species detected by GC/SAW appear to be quite similar to those obtained by headspace solid-phase microextraction (HS-SPME)-GC-MS, but the abundance ratios between these two methods are different. In addition to that, the discrimination of various thymus species by using
