Lipid Profiles of Tunisian Coriander (Coriandrum sativum) Seed

Coriander (Coriandrum sativum L.) seeds were harvested from the region of Korba (North-East Tunisia) in order to characterize their fatty acids, phytosterols, tocopherols and tocotrienols (tocols) profiles. Nine fatty acids, with petroselinic acid accounting for 76.6% of the total fatty acids, follo...

Zusammenfassung:Coriander (Coriandrum sativum L.) seeds were harvested from the region of Korba (North-East Tunisia) in order to characterize their fatty acids, phytosterols, tocopherols and tocotrienols (tocols) profiles. Nine fatty acids, with petroselinic acid accounting for 76.6% of the total fatty acids, followed by linoleic, oleic and palmitic acids, accounting for 13.0, 5.4 and 3.4%, respectively, of the total fatty acids were identified. Neutral lipids (NLs) were mainly composed of triacylglycerols (98.4%). Polar lipids were mainly composed of phosphatidylcholine as the major phospholipid (PL) subclass, whereas digalactosyldiacylglycerol was the major galactolipid (GL). Total sterols content was estimated to be 36.93 mg/g oil. Stigmasterol accounted for 29.5% of the total sterols. Other representative sterols were β-sitosterol, Δ⁷-stigmasterol and Δ⁵, 24-stigmastadienol, which accounted for 24.8, 16.3 and 9.2%, respectively. Gamma-tocotrienol was the predominant tocol at 238.40 μg/g seed oil. This was equivalent to 72.8% of the total tocols followed by γ-tocopherol (8.06%) and α-tocopherol (7.6%).
