The present investigation was carried out to determine the nutritional and functional properties of T. cucumerina. Water extracts of freeze dried flowers, fruits, and leaves of T. cucumerina were evaluated for their total phenolic content (TPC), total flavonoid content (TFC), antioxidant activity, α-amylase inhibitory activity, and fiber and mineral contents. Antioxidant activity, TPC, and TFC were significantly higher () in leaves than in flowers and fruits. A significant linear correlation was observed between the TPC, TFC, and antioxidant activities of plant extracts. Although, leaves and flower samples showed a significantly higher () amylase inhibitory activity than the fruit samples, the overall amylase inhibition was low in all three parts of T. cucumerina. Soluble and insoluble dietary fiber contents were significantly higher () in fruits than in flowers and leaves. Ca and K contents were significantly higher () in leaf followed by fruit and flower and Mg, Fe, and Zn contents were significantly higher () in leaves followed by flowers and fruits. In conclusion, T. cucumerina can be considered as a nourishing food commodity which possesses high nutritional and functional benefits for human health.
