Influence of Abiotic Factors on the Phytochemical Profile of Two Species of Artemisia: A. herba alba Asso and A. mesatlantica Maire

The species of Artemisia are well known in the Mediterranean region, especially Morocco, for their traditional uses and health benefit. In this study, we were interested two Artemisia, namely A. herba alba Asso mesatlantica Maire. These collected from different soils Central Middle Atlas (loamy, stony, limestone rocky soil) with atmospheres. Extraction essential oils leaves flowering tops was carried out by hydrodistillation Clevenger apparatus. Chemical composition analysis further using gas chromatography coupled mass spectrometry (GC-MS). Principal component (PCA) performed to determine similarities dissimilarities chemical compositions these six oils. results obtained showed that oil contents extracted vary one another according place harvest, altitude, soil type climate. yield is between 0.84% 2.19% (mL/100 g). revealed chemotype a subhumid humid atmosphere trans-thujone (33.78%), while camphor (46.19%) semi-arid atmosphere, vetivenic acid (14.91%) davana ether (14.64%) arid (18.39%) loamy stony atmosphere. As on main (44.86%), (41.08%). addition, HCA affirmed PCA allowed us distinguish four groups. Our findings observed differences isolated most likely related many factors such as climates regions samples collected, altitudes types.
