Callus was derived from the seedlings of Agastache rugosa(Labiatae). The growth rate of callus and the production of essential oil were studied with the variation of culturing conditions. 2, 4-D 2ppm in the medium was more effective for the production of essential oil than NAA 2ppm. The growth rate of callus and the production of essential oil were inhibited by the illumination of the light. The essential oils from Agastache rugosa and the callus cultivated on the medium containing 2, 4-D 2 ppm and kinetin 0.2 ppm were analysed by TLC, gas chromatography and mass spectrometry. These two oils showed different compositions. The main component of the plant oil, methyl chavicol was not contained in the callus oil.

Headspace solid phase trapping solvent extraction (HS-SPTE) and GC-MS was applied for the characterization of volatile flavors from fennel, anise seed, star-anise, dill seed, fennel bean, and Ricard aperitif liquor. Tenax was used for HS-SPTE adsorption material. Recoveries, precision, linear dynamic ranges, and the limit of detection in the analytical method were validated. There were some similarities and distinct differences between fennel-like samples. The Korean and the Chinese fennels contained trans-anethole, (+)-limonene, anisealdehyde, methyl chavicol as major components. The volatile aroma components from star anise were characterised by rich trans-anethole, (+)-limonene, methyl chavicol, and anisaldehyde. Additionally, principal component analysis (PCA) has been used for characterizing or classifying eight different fennel-like samples according to origin or other features. A quite different pattern of dill seed was found due to the presence of apiol (dill).

Background: In Korea, Agastache rugosa (Fisch. & C. A. Mey.) O. Kuntze is one of the well-known perennial plants belonging to Lamiaceae. This mint-fragranced plant has long been used for the treatment of abdominal pain, congestion, chills, and diarrhea since the Goryeo Dynasty. Although this plant has various medicinal properties, it is only used as a spice and for landscape purposes. Methods and Results: The objective of this paper was to review the chemical composition and biological properties of the essential oil of A. rugosa. Several studies reported that the essential oil contains more than 60 different chemical components of monoterpene and sesquiterpene hydrocarbons and oxygenated hydrocarbons. The major component is methyl chavicol (estragole), accounting for 64% - 88% of the oil. The chemical composition of this essential oil vaired widely according to the planting time, environmental conditions, planting distance, fertilizer application, and harvesting time. Conclusions: The essential oil of A. rugosa possesses various pharmacological properties such as antioxidant, antibacterial, anticancer, antiviral, nematicidal, antifungal, insecticidal, wrinkle improver, stress reliever, and Alzheimer's disease alleviator. Hence, the essential oil from A. rugosa could be used for the development of high value-added industrial products in the near future.
