| Abstract:
Equilibrium in combination with gas chromatography/mass spectrometry (GC/MS) was used to identify volatile compounds from the leaves of 76 individual plants of Agastache rugosa representing 16 regions in South Korea. Chemometric investigation of the intraspecific variability in volatiles led to identify five main chemotypes; estragole (Type 1) as the major component, and the other four chemotypes; methyleugenol (Type2), methyleugenol+limonene (Type 3), menthone (Type 4) and menthone+pulegone (Type 5). The Soraksan region collection was classified as methyeugenol type; Hambaeksan region collection, as methyleugenol +limonene type; Bongpyeong and Inje regions (two of three sample) collection as menthone type; Hongcheon and Inje regions (one of three sample) collection as menthone+pulegone type; and all of the others collections as estragole type. | |
