Chemical analysis of the essential oils from punica granatum, vitis vinifera and cuburbita maxima seeds grown in Lebanon by GC/MS+

Abstract

Eight major chemicals are identified after analyzing the essential oil of the seeds of three medicinal plants Punica granatum, Vitis vinifera and Cucurbita maxima, using Gas Chromatography/Mass Spectrometry (GC-MS). Only three of the identified chemicals (Farnesene, Docosane and Tetracosane) were found in all three samples, but in varying proportions. Trans-Squalene was found in Cucurbita maxima and Punica granatum only. The remaining four compounds (Octanoate ethyl ester, Doconoate ethyl ester, Palmiate ethyl ester, and Linoleic acid ethyl ester) were found exclusively in the Vitis vinifera seed oil, being probably the reason behind the precise application of this oil in traditional herbal medicine. A deep investigation of the medicinal uses of the identified constituents justifies many traditional beliefs concerning these seed oils.
