Abstract

Chemical composition and physicochemical analysis were established in carrot (Daucus carota) seeds from Zaria, Kaduna to investigate their potential uses. The oil extraction from Carrot seed was achieved through Soxhlet extraction method. Some of the physicochemical analysis was iodine value (67.007 /100 gram of KOH), saponification value (78.94 KOH/ gram), acid value (9.54 mg), relative density (0.9797), and free fatty acid (4.797%). The analysis of the seed oil is performed by FTIR and has allowed us to identify 3 functional groups in the oil of daucus carota of cultivated seeds in Zaria. These chemical compositions are carbonyl group for a cyclic 5-membered ring (C=O), methylene group (C-H), and aromatic alkenes (C=C). From the analysis of the chemical composition, it can be concluded that the active composite of cultivated carrot seed oil are C=O, C=C, and C-H.
