Abstract

|
The compositional changes of wormwood (Artemisia princeps var. orientalis) essential oils were studied under 4different storage conditions i.e., being exposed to air at 20 and 40oC. Sixty-four volatile compounds consisting of 24 terpenehydrocarbons, 18 alcohols, 11 ketones, 6 esters, 1 aldehyde, 2 hydrocarbons, and 2 oxides were identified on the basis of theirmass spectra characteristics and retention indices in original wormwood essential oils. Identified compounds constituted80.53% of the total peak area. Borneol (12.13%) was the most abundant compound, followed by α-thujone (8.66%), T-cadinol(6.67%), and 1,8-cineole (6.21%) in original wormwood essential oils. Under the condition of 40oC of temperature with thecap being opened for 3 min everyday respectively during 6 months of storage, the total amount of functional groups inessential oil determined by peak area percent were decreased by 79.45%, at most. The total level of monoterpenehydrocarbons decreased markedly in the aerobic condition and high temperatures. Whereas the total level of esters increasedsignificantly. Wormwood essential oils were stored in experimental conditions, with the changes in the volatile compounds ofessential oils being accelerated by high temperatures and contact with the atmosphere.
