Sixty-three different compounds, amounting to 88.8% of the total oil contents, were identified in the oil of M. charantia. It comprised of (Z)-3-hexenol (34.7%), (E)-2-hexenol (10.1%), and phytol (8.3%) as the major compounds. Linalool (5.8%) was the only monoterpenoid identified in a significant amount. Results from analysis of the oil of P. amarus revealed that eighty-two identified compounds were responsible for 87.6% of the oil content. The “stone-breaker” shrub oil was characterized by the dominance of linalool (36.4%) and phytol (13.0%). Moreover, compounds such as hexahydrofarnesyl acetone (3.4%), pentacosane (2.5%), and naphthalene (2.4%) occurred above 1%.

The needle oil of pinus caribaea morelet from Nigeria / Dorcas O. Moronkola in The journal of essential oil research, Vol. 21 N° 4 (Juillet/Août 2009)

The 44 oil constituents, obtained by hydrodistillation, were largely dominated by monoterpene hydrocarbons (83.6%). The present investigation revealed the abundance of limonene (42.9%) and β-phellandrene (24.4%). β-Caryophyllene (7.6%) occurred in a significant proportion among the sesquiterpenes.
