M Hassanein MM, El-Shami SM, El-Mallah MH. Investigation of lipids profiles of Nigella, lupin and artichoke seed oils to be used as healthy oils. 1. J Oleo Sci. 2011;60(3):99-107.
Nigella sativa, lupin and artichoke seed oils have been investigated. The oils were subjected to detailed studies using gas chromatographic analysis (GLC) for fatty acids (FA, as methyl esters) and whole sterols (as silyl derivatives). Whereas, high pressure liquid chromatography (HPLC) was employed for determination of molecular species of triacylglycerols (TAG), four sterol lipids (free and acylated sterols, FS and AS, and free and acylated sterylglycosides, FSG and ASG, as their anthroylnitrile derivatives) as well as tocopherol patterns (T). The results showed that the three seed oils are rich in oleic and linoleic acids whereas, lupin had high linolenic acid content. It was found that the TAGs of the three oils showed some similarity with sunflower oil. Lupin oil had higher sterol content and it was very rich in campe- and ?-sitosterol. Nigella sativa oil had a high content of isofucosterol, whereas artichoke oil was unique in having a high content of 5-stigma-, 7-stigma-, and avena- sterol. Concerning the FS and AS, nigella sativa oil had the highest content, whereas artichoke oil had the highest content of FSG and ASG. Nigella sativa and lupin oils contained over 90 % ?-T while, artichoke oil comprised about 100 % ?-T. It is recommended to use the three oils as healthy oils and folk medicine.
