Phytochemical Investigations in Antidiabetic Natural Products
Summary
Natural products have long served as a reservoir for antidiabetic agents, with phytochemical investigations elucidating the structures, biological activities and mechanisms of action of diverse plant metabolites. Phenolic compounds, such as phenolic acids and flavonoids, exhibit inhibition of carbohydrate-digesting enzymes, enhancement of insulin secretion and protection against oxidative stress induced by chronic hyperglycaemia. Terpenoids and alkaloids, meanwhile, have been shown to modulate insulin sensitivity and glucose uptake via interaction with cellular receptors and transporters. Recent methodological advances in extraction, chromatography and spectroscopic characterisation have accelerated the discovery workflow, while bioassay-guided fractionation and in silico modelling have refined target identification. Micro- and nanoencapsulation techniques are increasingly applied to improve the stability and bioavailability of key phytoconstituents. Collectively, these studies underscore the global significance of plant-derived antidiabetic leads, offering potential for cost-effective interventions in regions where traditional herbal medicine remains central to diabetes management.
