Crataegus × sinaica is a hawthorn that originated as a hybrid between two other hawthorn species, C. azarolus in series Orientales and C. monogyna in series Crataegus. It has been placed in the nothosection Orientaegus.[1] It grows in the central and eastern parts of the 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
[edit]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]
