Abstract
- The essential oils extracted from the cone scale (CS), seed (SE), and thin branch with leaf (BL) of Taxodium distichum harvested during the winter season were analyzed by gas chromatography-mass spectrometry. Up to 37 components were identified, accounting for more than 96% of the total oil volume in all samples. Monoterpenes (CS 93.4%, SE 85.2%, and BL 72.8%) represented the major constituents of the essential oils, followed by smaller quantities of sesquiterpenoids. Monoterpene hydrocarbons (MH) dominated, with limonene (CS 56.5%, SE 50.5%, and BL 43.8%) and a-pinene (CS 31.7%, SE 26.1%, and BL 16.2%) being the main constituents. Representative minor constituents in the CS oil are camphene (1.3%) and bornyl acetate (2.6%); in the SE oil, ß-myrcene (1.7%) and bornyl acetate (5.1%) were found; and in BL essential oil, ß-myrcene (3.1%) and bornyl acetate (6%). Sesquiterpene hydrocarbons (CS 4.6%, SE 7.8%, and BL 12.9%) were the other major subclasses of components, with caryophyllene (CS 4.1%, SE 6.8%, and BL 9.3%) as the main constituent. The only oxygen-containing sesquiterpene found was caryophyllene oxide (CS 1.5%, SE 5.5%, and BL 8.3%). The compounds could be of great interest in food, cosmetics, and pharmaceutical applications.
