Abstract

The mango (Mangifera indica L.), an economically significant tropical fruit, is widely valued for its nutritional, flavor and health benefits. While mango fruit is consumed extensively, other parts of the mango tree, such as leaves, are rich in bioactive compounds and hold untapped therapeutic potential. This study conducts a comparative analysis of the bioactive properties in the leaf extracts of ten mango cultivars (Surangudi, Fatkiri, Kalepad, Banganappalli, Imampasand, Malgoa, Peter, Neelam, PKM - 1, Kottur sinnarasam) from Tamil Nadu, India, to evaluate their antioxidant and antidiabetic activities. Fresh leaves were collected and processed using cold maceration for crude extraction, with their morphological traits, nutrient profiles and bioactive compound concentrations examined. Key compounds, including polyphenols and flavonoids, were quantified using standard methods to assess their total phenolic content (TPC) and total flavonoid content (TFC), with Malgoa and Imampasand showing higher concentrations. The antioxidant activity of the leaf extracts was determined via DPPH and superoxide radical scavenging assays, where Malgoa exhibited superior radical scavenging properties. Additionally, the antidiabetic potential was assessed by measuring ?glucosidase enzyme inhibition, with Malgoa and Imampasand demonstrating potent inhibition, suggesting their utility in managing diabetes. These findings emphasize the potential of mango leaves as a source of functional ingredients with health-promoting properties, supporting sustainable use of agricultural byproducts and the valorization of underutilized mango cultivars for therapeutic applications. This study highlights the significant bioactive diversity among cultivars, with implications for breeding programs aimed at enhancing mango's health benefits.
