Extraction and characterization of black seeds oil (Nigella sativa Linn)

Sarra Talab

Abstract :

Black seed oil is an essential oil extracted from the seeds, Nigella sativa Linn. Black seeds oil extracts from seeds via extraction with cyclohexane. The resulted oil was subjected to some characteristic tests. A positive test with the disappearance of the purple KMnO4 indicated the presence of double bond. The reddish own color appeared from reaction of oil with H2SO4 which confirm the presence of unsaturated bond. Also some physichemicals properties were examined: the color of the oil is yellowish own color, the density is 0.7 g/mL, peroxide value is 0.22 Meq/K, acid number is 7.9 mg/g and saponification value is 144.45 mg/g. The IR–spectroscopy indicates the presences of some expected functional groups.
