**4. Conclusions**

The quality of edible oil was decided based on physico-chemical properties. Wood apple seed oil values were represented an overall acceptance with respect to oil purity, stability, flavor, degree of unsaturation, and natural antioxidants. The viscosity of oil indicated that the degree of saturated fatty acids was approximately equal to the degree of unsaturated fatty acids and is assessed as of suitable quality for cooking and industrial purposes. GCMS characterization resulted in a greater amount of unsaturated fatty acids compared to saturated fatty acids. Hence, the seed is a remarkably good source to obtain essential fats and for cooking and frying. The presence of tocopherol in the seed oil indicated its potential as a good source for scavenging the free radicals. Nutritional and nutraceutical analysis of seed cake revealed a rich content of protein, carbohydrate, and total phenols, which are helpful in maintaining good health. The utilization of such underutilized fruit seeds facilitates an extra economic benefit to the local people.
