This experiment was conducted to obtain basic informations on the growth and the essential oils of Elsholtzia ciliate which is one of the native Korean aromatic plants and will be useful resources for medicinal, aromatic and ornamental uses. Seeds of E. ciliata were collected from Pyoungchang, Kangwon, were sown on April 10, 1997, and cultivated at the experimental plots of Yonam College of Agriculture in Chungnam. E. ciliate was harvested in full boom on Oct. Std. The plant height of harvested E. ciliate was 149cm. The fresh weight which was composed of 8% leaves, 789o stems, and 14% spikes was 1888. The contents of essential oil extracted from dried upper parts of whole plants, leaves, stems, and spikes by SDE method was 2.3%, 6.9%, 2.0%, and 8.3% respectively, which were significantly higher than other aromatic plants. The major components of essential oil analysed by GC/MS were rosefuran (42%), citral (14.88%), limonene (6.1%) as monoterpenesm and α-hamulene (6.4%) and germacrene-D (6.2%) as sesquiterpenes. While the major component of spikes is rosefuran, that of leaves and stems was citral. This experiment showed that E. ciliate was a very good aromatic plant for ornamental uses and as volatile oil crops, and new cultivating method needed to be developed for the future ornamental and aromatic recourses.
