Effect of Ecotype and Environment on Oil Content, Fatty Acid, and Sterol Composition of Seed, Kernel, and Epicarp of the Atlas Pistachio

The Atlas pistachio fruits are an important source of food due to their high fat content and medicinal interest in arid lands. For a better use, it is necessary understand the diversity distribution lipids fruit. purpose present study determine oil content, fatty acid, phytosterol composition using gas chromatography three ecotypes Algeria during two consecutive years. seed contents ranged from 32 47.8% depending on both year ecotype. Unsaturated acids (FA) represent at least 71% total FA. fruit contains considerable level phytosterols. highest unsaturated FA were observed Bechar regardless part indicated that quality varies according genotype environmental conditions, findings could help breeders for selection program management.
