Abstract
Nigella sativa is the plant raw material that is used in almost all branches of medicine because of its composition, which is rich in different types of vitamins and oils. The main product is black seed oil, used widely in medicine. This product has been known since ancient times and has been used for immunity, not knowing that this plant contains a range of main components that are very healthy. Different methods have been used to obtain oils in ancient times as well as in modern times, starting from the preparation of black seed, which was subjected to pressing by directly squeezing black seed oil without knowing exactly about its constituent conductive substances, as well as pressing of undesirable substances that accompany it. This increases the need to carry out a technological process controlled in such a way that the amount of ingredients is precisely known, at the same time, the black seed oil has complete purity without any conductive material. An advanced extraction method would enable a controlled extraction during which the process would be carried out in two stages. The first stage will be the extraction of the black seed with a suitable solvent, and in the second stage, the separation of oil from conducting materials of the black seed, which requires a complex process for separating the phases, and on the other hand, the use of an adequate solvent that has no contraindications during its use. The application of the extraction method by maceration is an excellent method for extraction, with the help of other extraction factors such as temperature, solvent, extraction time, and the rotation rate of the mixer. Good preparation of the raw material goes in favor of extraction, as well as the preliminary removal of moisture, which prevents the separation of the black seed oil phase from undesirable conductive materials.
