Chemical composition of Nigella sativa L. seeds

Nigella sativa L. is an annual herbaceous plant which is cultivated for its seeds and is classified as an edible plant. The proximate chemical composition of Turkish N. sativa L. seeds was investigated. The compositions of fatty acids and sterols of the extracted oil were studied. The contents of total polyphenols and tocopherols of the oil were also determined, and an analysis of water-soluble vitamins and minerals in the seeds was carried out. © 1993
