Quantitative Phytochemical Profiling, Nutritional Composition and Antioxidant Activity of Carica papaya (paw-paw) Leaves

Abstract

Introduction: Carica papaya commonly known as pawpaw is a rich medicinal plant with high nutritional value. This study focused on assessing the phytochemical composition, proximate analysis, and in vitro antioxidant activities of the leaves of Carica papaya to unravel its potential health benefits. Methods: The phytochemical composition, proximate analysis and DPPH free radical scavenging assay were determined using standard methods. Result: Quantitative phytochemical analysis of the leaves of C. papaya revealed the presence of daidzin, epicatechin, baicalin, myricetin, isorhamnetin in substantial quantity. Proximate analysis revealed significant carbohydrate content followed by ash, moisture, protein, fat and fibre content.  The scavenging property elucidated the antioxidant potential of Carica papaya leaves with more scavenging activity at concentrations of 10, 20, 40, and 80 mg/ml. Conclusion: Results from these findings suggest that Carica papaya leaves exhibit a rich phytochemical profile and a considerable nutritional value, thereby making them an important supply of bioactive compounds and nutrients. The study revealed that C. papaya leaves can be a good source of antioxidants which could help decrease oxidative stress and alleviate some complications associated with health ailments.
