Determination of fatty acids and active compounds in some Umbelliferae seeds (parsley, Celery, Coriander and Dill) at Commercial and laboratory oils

Abstract

The current study included using seeds of parsley Petroslinum crispum , Celery Apium graveolens, Coriander Coriandrum sativum and Dill Anethum graveolens belonging to the family of Umbelliferae to extract oils from them, the seeds brought from the local markets of Basrah city, and after that the seeds milled and dried. Oil was extracted from samples of seeds milled and dried using organic solvent extraction method, and used commercial pure oils for their comparison. The fatty acids were analyzed and active compounds in the commercial and laboratory oils by gas Chromotography and spectaophotometer mass, then the data was analyzed statistically we was following results: The fatty acids are effective compounds for commercial and laboratory oils were analyzed by gas chromotography spectaophotometer mass analysis, while was observed that the commercial parsley oil contains Palmitic acid and Stearic acid, commercial oil from celery contains Oleic acid, Linoleic acid, Palmitic acid, Palmitolic acid, Stearic acid and Erucic acid, also commercial oil from coriander contain the Linoleic acid, Oleic acid, Palmitic acid, Stearic acid and Erucic acid. Two acids Octadecadieoic acid and Cis -11-eicosenoic acid on the rated (5.76 and 3.53)% were in commercial oil of dill, and the results showed that the laboratory oils contain ratios of Oleic acid, Palmitic acid and Stearic acid, as well as contain non Common fatty acids . The results pointed that the commercial oils did not have any active compounds. while the active compounds in laboratory oils such as parsley, celery and dill were apoil. However celery and dill oils contained limonene, But the dill oil characted with carphon and coriander oil contained caryophyllene, As well as thier were other active compounds were founded in the laboratory oils, which played a major role in preservation.
