Abstract

Glyceride structure of SOS-7 halophyte oil was studied using the lipase hydrolysis technique. This halophyte sample was obtained from 1988 harvest planted in Ghardaka, on the border of the Red Sea, Egypt. The oilseed was ground and extracted for its oil using commercial hexane in Soxhlet extractor. The unsaturated fatty acids were found centralized in the 2-position of triglycerides, whereas oleic and linolenic acids showed more preference for this position. It was found that P₃ was the major component of GS₃, whereas P₂L and PStL; PL₂, POL and StL₂ are predominating among GS₂U and GSU₃ respectively. L₃ manifested itself as the principal constituent of GU₃ type. Sterol composition of the halophyte oil was determined by GLC as TMS derivative. It was found that the oil contains campsterol, β-sitosterol, stigmasterol and 7-stigmasterol of which 7-stigmasterol is the major sterol and constitute 52.4%.
