Abstract
The current work aims to study three seed cultivars of rapeseed (Brassica napus), as well as trying to provide a phytochemical insight of different rapeseed cultivars to be potentially cultivated as natural alternative hydrocarbon sources to petroleum hydrocarbons. The three seed cultivars, namely Heros, Sultan and Reandy were purchased from Britain, India and Sweden, respectively. After being cultivated, the seeds were collected, dried, and crushed. Oils from the crushed seeds were extracted with n-hexane as a solvent, and the attained oils were analyzed by GC-MS. The results showed that the tested oil seeds exhibited valuable phytochemical constituents, possessing increased percentages of long chain hydrocarbons. The 2,4-Decadinal (E,E)-(CAS) was the superior phytochemical compounds in Heros (18.73%) and sultan (29.35%) seed oils, However, it was the second prevalent compound in Reandy seed oils. Also, percentage of the hydrocarbons content of the reandy seed genotype was (39.91%) higher than that of the Sultan (17.78%) seed oils. The most prevalent fatty acids were shown to be 9-Octadecenoic acid all the three tested gen verities. Based on the obtained data, Good hydrocarb plant yields can be offered by Heros and reandy cultivars. Also as a seed oil, could be considered as efficient plant oil for the industrial utilization as non-edible oils or in the biodiesel production as a low emission renewable energy.
