PHYTOCHEMICAL BASIS AND PRODUCT DEVELOPMENT POTENTIAL OF MORUS ALBA L., CICHORIUM INTYBUS L. AND TRIGONELLA FOENUMGRAECUM L. FOR ANTIDIABETIC FUNCTIONAL THERAPEUTIC PRODUCTS

Diabetes mellitus is a major metabolic disorder characterized by persistenthyperglycemia and associated disturbances in carbohydrate and lipid metabolism. Theincreasing global burden of type 2 diabetes has stimulated interest in plant-derivedbioactive compounds and functional products that may complement establishedpreventive and therapeutic approaches. This review evaluates the phytochemicalcomposition, antidiabetic potential, and product-development prospects of Morus albaL. (white mulberry), Cichorium intybus L. (chicory), and Trigonella foenum-graecumL. (fenugreek), with particular emphasis on their suitability as raw materials forantidiabetic functional therapeutic products. Literature analysis indicates that M. albaleaves are characterized by 1-deoxynojirimycin, flavonoids, phenolic acids, andpolysaccharides; C. intybus contains inulin, chicoric acid, chlorogenic acid, othercaffeoylquinic acids, sesquiterpene lactones, and flavonoids; while T. foenum-graecumseeds are rich in galactomannan, 4-hydroxyisoleucine, steroidal saponins, trigonelline,polyphenols, proteins, and dietary fiber. These phytochemicals may influencepostprandial glucose absorption, carbohydrate-hydrolyzing enzymes, insulinsensitivity, oxidative stress, and lipid metabolism through complementary mechanisms.Clinical and systematic-review evidence is particularly developed for mulberry leaf andfenugreek, whereas evidence for chicory remains more heterogeneous and is dominatedby preclinical studies. The comparative analysis suggests that combining standardizedplant materials may provide a rational basis for developing multifunctionalantidiabetic products, provided that botanical authentication, chemicalstandardization, extraction conditions, dose optimization, stability, safety, and qualitycontrol parameters are established. The review proposes a product-developmentframework linking phytochemical markers with biological activity and qualitycharacteristics. Such an approach may contribute to the scientific development of plant-based functional therapeutic products within the framework of commoditychemistry and evidence-based phytotherapy.
