Chemical Compositions of the Essential oil of Aerva javanica Leaves and StemsKeywords: Aerva javanica , Amaranthaceae , Essential oil , Dry steam distillation , GC-MS Abstract: The essential oils from leaves and stems of Aerva javanica was extracted through dry steam distillation and the chemical composition of the oil was determined by Gas Chromatography-Mass Spectrometry (GC-MS). Total nineteen compounds were identified, representing 82.96% and 78.92% of the leaves and stems, respectively. The essential oil of Aerva javanica leaves was found to be rich in hentriacontane (21.48%), nonacosane (20.59%), heptacosane (19.78%), pentacosane (5.58%), octacosane (3.47%), triacontane (2.81%) and hexacosane (2.04%). Whereas the essential oil of stems was determined to be rich in nonacosane (23.26%), heptacosane (22.48%), hentriacontane (18.32%), octacosane (3.42%), triacontane (2.24%) and squalene (2.07%). Thirteen chemical constituents were common in the essential oil of both leaves and stems of Aerva javanica.
