Quantitative Phytochemical Evaluation and Phenolic Contents Of Extracts Of Citrullus Lanatus seed

Background: Citrullus lanatus (watermelon), a member of the Cucurbitaceae family, contains antioxidant molecules. It is a good source of carotenoids, vitamins, and minerals. Aim: The present study investigated the phenolic contents of aqueous and methanol extracts of C. lanatus seed. Methods: Aqueous and methanol extracts of C. lanatus seed were prepared using standard method. The phenolic contents of the plant extracts were determined using standard procedures. Results: Of the four phytochemicals quantified alkaloids were present in the highest amount, while phytate was completely absent. The methanol extract had significantly higher total phenol, tannins, flavonoids, and proanthocyanidin contents, relative to the aqueous extract (p < 0.05). Conclusion: These results indicate that C. lanatus seed is a good source of phenolic compounds and could be used as a natural constituent of food and medicines.
