Introduction: Diabetes mellitus is a common and complex metabolic disorder associated with high blood glucose levels leading to complications. Adopting a sedentary lifestyle characterized by low physical activity and consumption of high-energy diets contributes to the development of diabetes mellitus. Lifestyle changes and the use of pharmacological agents that target particular biochemical pathways involved in nutrient metabolism are currently used as management guidelines for managing risk factors associated with diabetes mellitus. The use of prescription medications for an extended period is linked to several negative side effects. Alternative management strategies of risk factors linked to diabetes mellitus involve the use of African leafy vegetables. African leafy vegetables contain a variety of biologically active compounds that provide health benefits. These crops have the potential to be a valuable source of new oral hypoglycemic agents for diabetes management. This review analyses the antidiabetic activities of nine African leafy vegetables whilst also defining the gap areas for future research. Methods: Data was acquired via electronic search engines of which only peer-reviewed papers published in journals were considered. Results: African traditional vegetables showed diverse in vitro and in vivo antidiabetic activities. Conclusions: There is an urgent need to document and use the knowledge of African leafy vegetables that have potential in the treatment and management of diabetes mellitus.

Carissa macrocarpa is commonly known as Natal plum. Its fruits are palatable and used in manufacture of jams while other parts of the plant are used in traditional medicine to treat various diseases. The main objective of current study was to screen the presence of and isolate the various phytochemicals applying standard procedures and to evaluate the in vitro antidiabetic activity using α-amylase inhibitory assay. The total methanol extract of flower (TMEF) of Carissa macrocarpa was subjected to several chromatographic procedures. Results demonstrated that TMEF of Carissa macrocarpa is characterized by the content of different constituents such as flavonoids, steroids, saponins, tannins and carbohydrates at different levels. Chromatographic isolation led to the isolation of kaempferol-3-O-robinobioside and caffeic acid, which were confirmed via using 1H, 13C, DEPT, COSY, HMQC and HMBC NMR spectroscopic analyses. TMEF exhibited α-amylase inhibitory activity with IC50 value of 65.4 μg/ml when compared to that of the acarbose (standard) (IC50 = 39.6 μg/ml). In conclusion, current investigation endorses the traditional use of Carissa macrocarpa as antidiabetic herb. Hence, the studied TMEF of Carissa macrocarpa may have the potential being nutraceuticals products for pharmaceutical applications as antidiabetic herbal remedy.

Introduction: Fruits of Litsea cubeba (Lour.) Pers. has been reported to be used traditionally in the treatment of diabetes in Darjeeling Himalayan region of India; though the hypoglycemic potential of the fruit has not been assessed till now, and the active constituents are yet to be discovered. Therefore, there is a necessity for the appraisal and characterization of the hypoglycemic properties of the fruits. Methods: Fresh fruits were collected and sequentially extracted with solvents of gradient polarity. In vitro antidiabetic activity was performed by α-amylase and α-glucosidase inhibitory assays. Free radical scavenging activity was performed by DPPH, ABTS, TPTZ (FRAP assay), NO and OH radical scavenging assays. To identify the bioactive components, GC-MS analysis was also performed. Result: Phytochemical screening of secondary metabolites in different solvent extracts showed the presence of phenols, flavonoids, alkaloids, cardiac glycosides, tannins, saponins, and anthocyanins. Methanolic extract exhibited highest antidiabetic potential with IC50 values of 514.9 μg/ml and 1435.7 μg/ml in α-amylase and α-glucosidase inhibition assay respectively followed by ethanol extract. Significant free radical scavenging activities were also found in the alcohol extracts. GC-MS analysis revealed the presence of principle compounds like oleic acid, morin, apigenin etc. which might be responsible for hypoglycemic activity. Conclusion: Here we report the appraisal of traditional usage of L. cubeba (Lour.) Pers. fruits based on in vitro antidiabetic and antioxidant assays along with GC-MS characterization of potent molecules. Our study confirms the traditional knowledge of the people of Darjeeling Hills regarding the use of the fruit of this plant in curing diabetes.

Introduction: Chicory(Cichoriumintybus) commonly known as kasni has health benefits such as improving liver health, digestion, boosting immune system possibly because of its water soluble dietary fibres and polyphenols. A diet rich in polyphenols and fibers helps in lowering cholesterol leading to less plaque formation, preventing blockage and risk of stroke. Owing to the fact that these polyphenols may reduce the elevated glucose the present research work was undertaken to extract the polphenols from Chicory roots and evaluate their antioxidant and hypoglycemic potential. Materials and Methods: Polyphenol rich fraction of root extract was subjected to estimation of total phenolic estimation and free radical scavenging activity using various antioxidant assays. The antidiabetic potential of the polyphenol rich fraction was also estimated using Alloxan Induced Diabetic Rat model. Results: The total phenolic content of the polyphenolic fraction was found to be 30.23\μg/ml. The IC50 values for DPPH and ABTS assay for the polyphenolic fraction were found to be 60\µg/ml and 4.2mg/ml respectively. The TEAC value was found to be 1.178 mm. Administration of polyphenol rich fraction (30 mg/kg, p.o.) decreased elevated SG from 122mg/dl to78.66mg/dl on 14th day (***p\<0.001). Also a significant reduction in triglycerides (**P\<0.01), total cholesterol (**P\<0.01), serum LDL (**P\<0.01) and serum alkaline phosphatase (**P\<0.01) was observed at 30 mg/kg, p.o. However, serum HDL was found to be elevated with no change in serum insulin (*P\<0.05). Conclusion: It can be concluded that the polyphenol rich fraction of Chicory roots possess a strong hypoglycemic potential probably due to their antioxidant activity.
