Abstract
Abstract: In this study, three of Egyptian Artemisia monosperma and two Tetraena simplex plants genotypes were selected from sinai, Egypt and used to cold pressing method for extract crude oil from Artemisia monosperma and Tetraena simplex dry plants., the obtained results could be summarized as the following:- the genotypes to north Sinai under study produced about 28% of crude oil by weight per kg of the dry Artemisia plant. But with regard to, estimation of fatty acids concentration in Artemisia plant of north Sinai so that to the fatty acids (FAA) and also are the genotypes to South Sinai under study produced crude oil by weight per kg of the dry Tetraena simplex plant. But with regard to, estimation of fatty acids concentration in Artemisia plant of north Sinai so that to seven to fatty acids (FAA) so that to the results showed that the genotypes were different in concentrations of fatty acids to Artemisia monosperma plant. So, genotype No. 2 (G. 2) showed a highest concentrations of sample, as 2.73% capric acid, 4.42% Palmitic acid, 5.32% Lauric acid, 39.19% Heneicosanoic acid and also the results showed that the genotypes were different in concentrations of fatty acids to Tetraena simplex plant, so showed a highest concentrations of sample (G2) 7.34% Stearic acid and 2.9 Oleic, than also to (G1).64 Stearic acid and .49 Oleic.
