"Crataegus sinaica" Boiss. grows in the mountains near Saint Catherine in South Sinai, Egypt, where it is known as Za'rur or Za'rur al-awdiyah. [Täckholm, V. (1974). Students' Flora of Egypt, Published by Cairo University.] Gas-liquid chromatography of lipoidal matter of the seeds of "C. sinaica" indicated that the seeds consist mainly of a mixture of a series of n-alkanes (75.75%). Sterols only represent 7.17% of the total unsaponifiable fraction. Analysis of the fatty acids from "C. sinaica" as methyl esters showed that the oil is rich in unsaturated fatty acids (86.86%). The major fatty acid is linolenic acid (C18:3) representing 38.43% of the total fatty acids mixture, followed by oleic acid (C18:1) 27.53%, and linoleic acid (C18:2) 20.89%. In addition, the results revealed the presence of stearic acid (3.69%) and palmitic acid (9.45%). [Refaat A. et al. (2008). Phytochemical and Biological Investigations of "Crataegus sinaica" Boiss. (Rosaceae). Master thesis, Cairo University, p.108. Egypt.]
