Abstract: Two stocks; with and without seed coat, of dried Crotonpenduliflorus seeds were analyzed using standard methods for proximate and mineral compositions. Oils were also extracted from the two different stocks and their physicochemical properties were determined. Results of these analyses were compared to study the effects of absence of seed coat on the chemical composition of croton seeds. This work revealed that the sample without coat is less susceptible to microbial degradation and rich in minerals. In addition, oil from sample with coat is not fit for human consumption and more susceptible to oxidative rancidity.
