الملخص

The oil content of the seeds of Lepid/"um sativum (Brassicaceae) known asGarden cress was detennined by extraction with Petroleum ether 40 — 60 QC ina Soxl1let extraction apparatus. The physical properties such as colour,refractive index, relative density and viscosity were determined as well as thechemical properties namely: acid, saponification, iodine, peroxide andunsaponfication values. Some of the detennined values were in agreementwith published data in the literature.Phytochemical and TLC screening of the seeds confirmed the presence oftriterpenes, sterols, flavonoid aglycones and Phenolic compounds.The composition of oil was determined by GC/MS analysis and the followingcompounds were fotmd:-Unsaturated fatty acidsSaturated fatty acidsHydrocarbons (heptacosane)Acetylenic compoundSterolsTriterpenes79.56%l6.87%0.18%0.'l3%2.24%0.14%The unidentified compounds represented approximately 1.23%. The lowcontent of emcic (8.76%) in comparison with linolenic acid (52.55%) wasobserved and the persence of the triterpene derivative of gedunin (0.09) wasdiscussed in relationship to its biogenetic origin.Data in the literature based on previous studies showed some differences inthe composition and yield, which may be due to variations in climaticconditions, soil or geographic location.
