Equilibrium headspace analysis connected with gas chromatography/mass spectrometry was used to identify volatile compounds released from the leaves of 73 individual plants of Agastache rugosa collected from 11 sub-regions in South Korea. Chemometric investigation of the infra-specific variability in volatiles led to identify five main chemotypes; elaborated estragole (Type 1) as the major component, and the other four chemotypes, characteristically contain monoterpenois compounds, isomenthone (Type 2), pulegone (Type 3), limonene (Type 4) and isomenthone+pulegone (Type 5), In these chemotypes, pulegone, limonene and isomenthone+pulegone types revealed that the diversity of new chemotypes were present in Korea.

Changing lifestyles in developed countries have led to dramatic increases in demand for natural products, particularly over the last decade. More varied use has been made of oils and herbs in cooking, and oil components are now being regarded as safe alternatives to synthetic food additives and crop protection substances. Volatile compounds among the secondary metabolites in plants have a great potential for their industrial application. With the development of advanced analytical technologies, various studies have been conducted on chemical properties, biosynthetic pathways, and functional bioactivity of the essential oil compounds in plants. Genetic studies, however, for these compounds have not been actively conducted, which is mainly due to difficult methodologies and their high cost of analytical instruments. One of the most difficult procedures for analysis of volatile compounds is the step of their extraction from plants. A few methodologies of extraction and trapping for these compounds have been introduced in terms of different experimental purposes. Recently, either equilibrium headspace autosampler or solid-phase microextraction(SPME) coupled with gas chromatography-mass selective detection was introduced to be a rapid and reliable method for qualitative evaluation of volatile compounds including terpenes and phenylpropenes in the aromatic plant germplasms and comparison between natural and synthetic compounds. In this study, we described the chemical properties of volatile compounds extracted from plant resource and introduced the various analytical techniques for their isolation and identification. We would discuss later the possibility of these analytical technologies for application to quality evaluation of volatile oil compounds and cultivar development.
