Essential oil components were analysed in forty seven individual plants of Elsholtzia splendens collected from eight different regions in Korea to identify their chemotypes. Major oil components of chemotype 1 was dihydrotagentone (75%) and naginataketone and elsholtziaketone were not detected at all. Chemotype 2 was naginataketone (NK) type which content was more than 60%. Chemotype 3 had more than 60% of elsholtziaketone (EK) as major volatile oil. EK type and NK type plants selected were maintained stably in their progenies after seed generation. Naginatketone and elsholtziaketone had functional properties such as antioxidation and antibacteria.

Volatile compounds, isolated from Elsholtzia splendens using simultaneous steam distillation extraction (SDE) and headspace solid phase microextraction (HS-SPME), were analyzed by gas chromatography/mass spectrometry(GC-MS). Twenty-nine compounds, comprising 3 aldehydes, 7 alcohols, 11 hydrocarbons, 5 ketones, and 3 miscellaneous ones, were tentatively identified from volatile compounds of Elsholtzia splendens flowers. From leaves, 30 compounds, comprising 3 aldehydes, 6 alcohols, 11 hydrocarbons, 6 ketones, and 11 miscellaneous ones, were tentatively identified. Volatile compounds extracted by HS-SPME in E. splendens flowers were 3 alcohols, 18 hydrocarbons, 3 ketones, and 2 miscellaneous ones. In leaves, 31 compounds, comprising 7 alcohols, 15 hydrocarbons, 7 ketones, and 2 miscellaneous ones, were tentatively identified. Major volatile compounds identified by SDE and HS-SPME were naginataketone and elsholtziaketone, which were identified as aroma-active compounds, representing characteristic aroma of E. splendens.

Volatile compounds in Elsholtzia splendens were extracted by solid phase microextraction (SPME). Two kinds of SPME fiber, carboxen/polydimethylsiloxane (CAR/PDMS) and polydimethylsiloxane (PDMS) were used to determine the selectivity of the fibers to the different flavor compounds present in the Elsholtzia splendens. Identification of volatile compounds was based on the linear retention indices (RI) and the comparison of their mass spectra with those of on-computer library. Thirty compounds were identified in the volatile compounds extracted by CAR/PDMS fiber, including 1 aldehyde, 5 alcohols, 3 hydrocarbons, 17 terpene hydrocarbons, 3 ketones and 1 miscellaneous. And 5 alcohols, 3 hydrocarbons, 18 terpene hydrocarbons, 3 ketones and 2 miscellaneouses were identified in PDMS fiber. These results suggested that the selectivity of PDMS fiber was similar to that of CAR/PDMS fiber in Elsholtzia splendens. The major volatile compounds were naginataketone and elsholtziaketone in Elsholtzia splendens.
