Crataegus × sinaica is a hawthorn that originated as a hybrid between two other hawthorn species, C. azarolus in series C. monogyna in series Mediterranean region on rocky mountain slopes^[1]. In Egypt it grows in the mountains near Saint Catherine in South Sinai, where it is known as Za'rur or Za'rur al-awdiyah.^[2]

Chemistry

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%).^[3]
