Many monoterpen-erivatives are contained in edible plants. Some monoterpen-derivatives have been assessed as negative factors in the food safety. Among them thuone and 4-caranone are important toxic constituents of many plant essential oils. In this study, convenient detection methods of thujone and 4-caranone in oil were developed. The colour reactions of toxic thujone and 4-caranone were performed in oder to detect those in foods and oils. Sodium pentacyanonitrosylferrate (II) react with thujone to produce thujzoximinocarboxylic acid which becomes the six ligand in the ferrate complex (red colour reaction for thujone). Sodium pentacyanonitrosylferrate (II) cleaves 4-caranone to the red ferrate complex of caranketonic acid.

This study investigated the chemical composition of Artemisia princeps var. orientalis (Pampan) Hara (ssuk in Korea) essential oil and the quantitative changes of major terpene compounds according to the time of harvest. The essential oils obtained by hydrodistillation extraction from the aerial parts of ssuk were analyzed by GC and GC-MS. The essential oil composition of ssuk was characterized by higher contents of mono- and sesqui- terpene compounds. Ninety-nine volatile flavor compounds were identified in the essential oil from ssuk harvested in 2010, with camphor (11.9%), ${\beta}-caryophyllene$ (9.11%), dehydrocarveol (8.51%), and borneol (7.72%) being the most abundant compounds. Eighty-three compounds were identified in the essential oil from the plant harvested in 2011, with borneol (12.36%), caryophyllene oxide (12.29%), ${\beta}-caryophyllene$ (10.24%), camphor (9.13%), and thujone (8.4%) being the most abundant compounds. Eighty-four compounds were identified in the essential oil from the plant harvested in 2012, with ${\beta}-caryophyllene$ (20.25%), caryophyllene oxide (14.63%), and thujone (11.55%) being the major compounds. Eighty-nine compounds were identified in the essential oil from the plant harvested in 2013, with thujone (23.11%), alloaromadendrene oxide (12.3%), and ${\beta}-caryophyllene$ (11.48%) being the most abundant compounds. Thujone and aromadendrene oxide contents increased significantly from 2010 to 2013, while camphor and dehydrocarveol contents decreased significantly during those 4 years. The quantitative changes in these 4 compounds according to the time of harvest can served as a quality index for ssuk essential oil. The ecological responses to recent climate changes may be reflected in the chemical components of natural plant essential oils.

In this study, changes in the volatile compounds of Artemisia capillaris essential oil were investigated under six different storage conditions for 6 months. The essential oil was collected by steam distillation and analyzed by a gas chromatography-mass selective detector (GC-MSD). Seventy-five volatile compounds were identified from the fresh essential oil of Artemisia capillaris. During storage, the total levels of aldehydes, alcohols, and ketones slightly decreased and the level of hydrocarbons greatly decreased; the total level of esters also decreased in the essential oil. Notably, the levels of carvacrol, eugenol, myrcene, 1,8-cineole, caryophyllene, coumarin, ${\alpha}-thujone$, ${\beta}-thujone$, borneol, and ${\gamma}-terpinene$, known as antioxidants and antimicrobial agents, decreased during storage. Finally, aerobic storage conditions caused greater reductions in some compounds even at low temperatures.

Volatile aromatic compounds collected from raw and roasted mugwort (Artemisia asictica nakai) leaves by the Tenax trap and some major volatile compounds were separated and identified by GC-MS. The identified compounds were tested for the antimutagenic and mutagenic activities against aflatoxin B$_1$(AFB$_1$) using their authentic compounds. Six compounds (myrcene, cineole, camphor, caryophyllen, coumarin, and farnesol) showed antimutagenic activities, but 2-pyrrolidine and thujone showed mutagenic activities. 1-Acetylpiperidine formed during roasting mugwort leaves exhibited mutagenic activities. When the mutagens and antimutagens were mixed, the mixture reduced the mutagenicity of AFB$_1$. These results suggested that the extract of mugwort leaves is not mutagenic and so the mugwort leaves might be used as a food and as medicinal sources without mutagenicity.
