[en] The Nigella Sativa, eastern plant from the Mediterranean basin and other areas of
the world, is very much used as condiment and medicinal application. The
microwave extraction allows to obtain oils in a very short time and with a better
quality and yields. The GC and GC/MS analysis of oils shows that are rich in volatile
of biosynthesis compounds such as the p-cymene and the thymoquinone which have
medicinal properties. The undesirable products caused by the reactions of hydrolysis
and the heating effect such as acids, alcohols and oxides are relatively reduced. The
monoterpenes and ketones constitute the principal classes of our oils.
In addition, the analytical study reveals that the seeds cultivated in the arid regions
are rich in thymoquinone which constitutes the principal active component of Nigella
Sativa seeds .
