This research is about the natural product of coriander, or the Coriandrum species. The bioactive molecules and the health effects of this plant are constantly discussed. This paper is parallel with those publications, investigating the composition of the herb. The results of current study indicates that the Coriandrum seed is a source of fatty acids. From the publications, petroselinic acid or (6Z)-octadecenoic acid, is the major fatty acid in the coriander extracts. Previous articles reported on coriander’s chemical constituents, biological activities of the coriander’s seeds and leaves, as well as the coriander products in the retail. Indeed, coriander has a lot of uses either as a traditional medicines or spices. Different forms of coriander samples were subjected to a simple maceration by using chloroform. From the chromatographic purification of the seed crude extract, its component could include anisaldehyde, as one of the aromatic aldehyde. It is concluded that the lipid-containing fraction of the coriander seed could also consist of dipetroselin, a diglyceride.
