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

Abstract

re-Abstract 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 ab-sent. 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.
