Seasonal variations in essential oil of aerial parts and roots of an Artemisia absinthium L. population from a Spanish area with supramediterranean climate (Teruel, Spain)

摘要: The seasonal variation of essential oil composition aerial parts and roots Artemisia absinthium L. has been investigated. It was obtained from individuals growing wild in Teruel (Spain) by means hydrodistillation (aerial parts) or simultaneous distillation extraction (roots), analyzed GC/MS GC/FID. Results showed a predominance oxygenated monoterpenes (81.4–89.1%) parts; mainly (Z)-epoxyocimene (49.3–71.5%), (Z)-chrysanthemyl acetate (7.6–18%) linalool (0.7–10.4%). In spite the high intrapopulational variability, significant variations were observed for these three compounds. Root amount hydrocarbon (43.8–55.1%) monoterpenic esters (36.6–41.5%) with noticeable stability except some allelopathic monoterpenes. As A. is typical invasive species, knowing compounds may be first step to study their release soil as source natural he...
