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]References1. ^1 2 Christensen, K.I. (1992). Revision of Crataegus sect. Crataegus and nothosect.
