Abstract

Plukenetia conophora fresh leaves were obtained from a farm in the Surulere Local Government Area of Oyo State, Nigeria. The plant is a climber which normally found support in kola nut or cocoa tree. Standard method was used for the extraction of the oil. The oil was analyzed using gas chromatographic and gas chromatography coupled with mass spectrometric methods. Fifteen compounds were identified in the leaves. The most abundant compounds in the oil were oleic (9-octadecenoic) acid (29.8%) and palmitic (hexadecanoic) acid (14.36%), while the less abundant compounds are 6-tridecenoic acid (9.05%) and 9-octadecenoic acid,1,2,3-propanetryl ester (6.24%). The characteristic of this oil is the presence of long chain fatty acids. This study seeks to evaluate the chemical constituents of the oils of P. conophora leaves and how to harmonize them in pharmaceutical and industrial uses.

 

Key words: Plukenetia conophora, leaves, oil, gas chromatography (GC), gas chromatography coupled with mass spectrometric methods (GC-MS).
