Physicochemical characteristics of Nigella seed (Nigella sativa L.) oil as affected by different extraction methods.

The physicochemical properties of crude Nigella seed (Nigella sativa L.) oil which was extracted using Soxhlet, Modified Bligh-Dyer and Hexane extraction methods were determined. The effect of different extraction methods which includes different parameters, such as temperature, time and solvent on...
