The aim of this research was to assess the nutraceutical potential of Hura crepitans seed oil in food chemistry. For that, we determined the phytochemical composition, physicochemical parameters, mineral composition, as well as proximates of the oil under study. The yield of the oil obtained by the Soxhlet method was 47.8 ± 0.2%. According to the phytochemical screening result, the oil contained saponin, alkaloid, terpenoids, steroids, and cardenolides. Quantitative analysis of proximates for the Hura crepitans seed oil displayed 10.1 ± 0.4% of protein, 19.4 ± 0.1% of crude fibres, 14.5 ± 0.5% of carbohydrates, 5.3 ± 0.2% of water, and 2.9 ± 0.1% of ash. Some selected physicochemical parameters such as refractive index, pH, and specific gravity were 1.47; 5.2; and 0.80, respectively. Cloud point was 6.20°C. Metal content determination revealed the presence of mineral substances such as magnesium (119.51 ± 0.25 mg/kg), potassium (4.25 ± 0.04 ppm), iron (4.01 ± 0.03 mg/kg), manganese (3.66 ± 0.02 ppm), sodium (2.18 ± 0.02 ppm), calcium (0.11 ± 0.001 ppm), zinc (0.04 ± 0.001 μg/g), and cadmium (0.0028 ± 0.0004 mg/kg). However, such minerals as nickel and lead were not detected. The structural analyse was carried out based on physicochemical properties and spectroscopic data of the Hura crepitans seed oil. The results of the research proved the nutraceutical potential of this oil to use as raw materials in various areas of industry.
