Chemical composition and bioactive compounds of Cucurbitaceae seeds: Potential sources for new trends of plant oils

4. Conclusion 
The present study demonstrated that pumpkin, watermelon, and melon seeds contain 
many nutrients as protein, fibers and minerals which indicate their potential uses as dietary 
supplement in relevant applications. When compared to pumpkin and watermelon seed oils, 
melon seed oil was a rich source of many bioactive substances such as phytosterols and 
phenolic compounds. These bioactive compounds may be used as natural antioxidants for 
industrial applications. Besides, the high-unsaturated fatty acid level makes the watermelon 
seed oil nutritionally valuable. In the light of these favourable characteristics, appropriate use 
of melon, watermelon, and pumpkin seeds makes them a good example for the valorisation of 
processing fruits’ by-products.
