Phytochemical Analysis of the Essential Oil from Aerial parts of Pulicaria undulata (L.) Kostel from Sudan

The yield of steam distillation of aerial parts of Pulicaria undulata essential oil (2.5%); and its chemical constituents were determined. The Gas Chromatography-Mass Spectrometery (GC/MS) technique was used for the analysis of the oil. Several oil components were identified based upon comparison of their mass spectral data with those of reference compounds published in literature or stored in a computer library. The oil was characterized by the high content of the oxygenated monoterpenes which constituted 68.28 % in which (+)-carvotanacetone (55.87 %) was the major constituent. Pulicaria undulata oil was characterized by the presence of many components which could have numerous applications in food, pharmaceutical and perfume industries
