Phytochemical Properties and Antidiabetic Applications of Syzygium Species

Syzygium, a genus within the Myrtaceae family, harbours a diverse array of secondary metabolites that underpin its traditional and emerging antidiabetic uses. Across species such as Syzygium cumini and related congeners, seeds, fruits, leaves and bark yield rich profiles of phenolic compounds, flavonoids, tannins, alkaloids and triterpenoids. These phytoconstituents exhibit potent antioxidant and anti-inflammatory activities, modulate glucose-metabolising enzymes and enhance insulin sensitivity. In vitro studies have demonstrated that extracts inhibit α-amylase and α-glucosidase, key enzymes in carbohydrate digestion, thereby reducing post-prandial hyperglycaemia. In vivo experiments reveal that seed powders and purified compounds attenuate diet-induced obesity, improve lipid profiles and protect against oxidative damage in pancreatic and hepatic tissues. Collectively, this body of work underscores the global significance of Syzygium species as a source of bioactive agents for managing type 2 diabetes and its complications, while ongoing research aims to refine extraction methods, elucidate mechanisms of action and advance clinical evaluation.
