Essential Oil Variability and Biological Activities of Tetraclinis articulata (<scp>Vahl</scp> ) <scp>Mast</scp> . Wood According to the Extraction Time

In the present work, the hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD) kinetics of essential oil extracted from Tetraclinis articulata (Vahl) Masters wood was conducted, in order to assess the impact of extraction time and technique on chemical composition and biological activities. GC and GC–MS analyses showed significant differences between the extracted essential oils, where each family class or component presents a specific kinetic according to extraction time, technique and especially for the major components: camphene, linalool, cedrol, carvacrol and α-acorenol. Furthermore, our findings showed a high variability for both antioxidant and anti-inflammatory activities, where each activity has a specific effect according to extraction time and technique. The highlighted variability reflects the high impact of extraction time and technique on chemical composition and biological activities, which led to conclude that we should select essential oils to be investigated carefully depending on extraction time and technique, in order to isolate the bioactive components or to have the best quality of essential oil in terms of biological activities and preventive effects in food.
