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.

The liver is the organ in charge of homeostasis and metabolism of sundry substances (endogenous and exogenous, including drugs); but when these are metabolized, they generate more toxic and/or reactive metabolites, that can damage the liver causing cirrhosis, steatosis and/or hepatocarcinoma. Human have been used several medicinal plants (MP) since ancestral times to treat their ailments, diseases and liver disorders, including Sylibum marianum. This MP is used in the treatment of jaundice and other biliary diseases, as well as in support therapy for edible mushrooms poisoning and in the treatment of some hepatic diseases. From this medicinal plant, silymarin (SLM, mixture of flavonoids) is obtained, it has an important antioxidant, anti-inflammatory and hepatoprotector effect. The last activity has been demonstrated through several preclinical and in some clinical studies. To date, a few clinical studies describe the hepatoprotective and/or nephroprotective effect of SLM against the damage caused by anti- TB drugs, methotrexate and in cases of type II diabetes mellitus or chronic hepatitis C. Nevertheless, this type of research is more frequent in preclinical trials (using rats or mice) or in vitro assay.

Introduction: Diabetes mellitus (DM) is an endocrine disorder characterized by high blood glucose levels. One of the approaches for treating DM is by regulating the postprandial blood glucose via inhibition of \α-glucosidase enzymes. Seagrass is known as a plant containing bioactive compounds, especially for therapy antidiabetic. This research aims to evaluate the \α-glucosidase inhibition activity of three species seagrasses (Enhalus acoroides, Thalassia hemprichii and Cymodocea rotundata) from the Banten Bay, Indonesia. Methods: The extracts of all parts (root, leaf, and stem) from three seagrasses were prepared with maceration method using 80\% ethanol solvents. The \α-glucosidase inhibitory activity was conducted by microplate reader at 400 nm using acarbose as a positive control. Furthermore, the kinetics of \α-glucosidase inhibition, phytochemical screening, and total phenolics content were evaluated against extract which has the most potential \α-glucosidase inhibition. Results: The result showed that the 80\% ethanol extracts of Enhalus acoroides (IC50 values 168.15 \± 2.71 g/mL) had the most potential \α-glucosidase inhibitors activity compared with the positive control acarbose, Thalassia hemprichii and Cymodocea rotundata (IC50 values 197.27 \± 3.07 g/mL, 425.86 \± 5.15 g/mL and 429.28 \± 8.89 g/mL). The kinetic type of inhibition against \α-glucosidase was noncompetitive inhibition. The phytochemical compounds were phenols, flavonoid, terpenes, and tannin with the total phenolic content was 28.76 \± 2.46 mgGAE/g. Conclusion: Enhalus acoroides has the strongest inhibitor of \α-glucosidase and can be further developed for DM therapy agents.

Background: Advanced glycation end products(AGEs) are formed by non-enzymatic glycation of proteins that enhance vascular permeability in both micro and macro vascular structures by binding to specific macrophage receptors. AGEs affect nearly every type of cells and molecule in the body and play causative role in the vascular complication in diabetes mellitus. Materials and Method: AGE reaction solution was constituted with 10mg/ml bovine serum albumin in 50mM sodium phosphate buffer (pH 7.4) and 0.02\% sodium benzoate into 0.2M fructose and 0.2M of glucose. 2.5 ml of the reaction mixture was treated with lutein (10, 20, 40, 60, 60, 80, 100, 120, 140 \μ g/ml in methanol). Amino guanidine was used as the positive control. After incubating at 37\°C for 7 days, the fluorescence intensity of the reaction was determined at excitation and emission wavelength of 350 nm and 450 nm, respectively, using a multimode reader. The percentage activity was calculated with respect to solvent control. Result: 7 days of exposure to lutein showed a maximum inhibition of 89.27\±0.24 \% at 140\μg/ml and Amino guanidine exhibited 90\% of inhibition. The IC50 of Lutein for AGE inhibition was found to be 77.78\μg/ml and for AG, 72.66\μg/ml.Conclusion: The non-enzymatic adduct formation between the keto group of sugar and amino group of proteins is one of the molecular basis of diabetic complications in hyperglycaemic state. Inhibition of this process will be useful in the management of diabetic complications. Lutein showed dose dependent inhibitory effect on the protein glycation.Hence, it may be used for the management of diabetic complication.

Context: The leaves of Lagerstroemia speciosa (L.) Pers. (banaba) have been consumed traditionally in several Southeast Asian countries for the treatment of diabetes mellitus. The plasma glucose lowering actions of this medicinal plant were proposed to be linked with several mechanisms of action. However, its inhibitory actions against \α-amylase and \α-glucosidase, which play a major role in the regulation of postprandial plasma glucose, have not been clearly established. Aims: This study thus aimed to investigate the effects of Lagerstroemia speciosa (L.) Pers. aqueous and ethanolic leaf extracts (LSA and LSE extracts, respectively) on in vitro carbohydrate-digesting enzyme activities and enzyme kinetics. Settings and Design: In vitro carbohydrate-digesting enzyme activity assay. Materials and Methods: The activities of \α-amylase and \α-glucosidase were indicated by the amounts of maltose and p-nitrophenol generated in the reactions, respectively. Statistical analysis used: The data were analysed by using one-way ANOVA, followed by Bonferroni post-hoc test. Results: The LSA extract significantly inhibited both \α-amylase and \α-glucosidase enzymes with the IC50s of 1.21\±0.16 and 49.71\±0.86 \μg/mL, respectively. Meanwhile, the LSE extract selectively inhibited \α-amylase activity (IC50 = 22.21\±4.00 \μg/mL) with no apparent inhibition against \α-glucosidase activity. Both LSA and LSE extracts inhibited \α-amylase enzyme in a mixed inhibition manner whilst the LSA extract also acted as a mixed inhibitor against \α-glucosidase enzyme. The extracts possessed higher binding affinities toward the enzymes, indicated by the lower Ki values, when compared to acarbose (positive control). Conclusion: These results suggest the potential use of the extracts for a control of postprandial plasma glucose.

Background: Diabetes mellitus become one of the biggest global health problems of the 21st century. Type 2 diabetes play role for the majority of cases of diabetes worldwide which is characterized by the increase of postprandial blood glucose level. Maintaining postprandial glucose level through inhibition of \α-glucosidase is one of the essential strategies in the treatment of diabetes. Inhibitory effect of \α-glucosidase was commonly used to identify active compounds potentially to treat diabetes. Natural resources have potency as antidiabetic that can be used in diabetes treatment. Objective: The objective of the study is to separate active fraction in the crude extract of Garcinia hombroniana leaves to facilitate obtaining a pure biologically active compound as the \α-glucosidase inhibitor. Methods: Fractionation to separate active fraction was performed using column and thin layer chromatography methods while \α-glucosidase inhibitory activity assay was performed in vitro using spectrophotometric methods at \λ 400 nm. Results: Ethyl acetate and methanol extract of G. hombroniana yielded 14 and 12 fractions, respectively. Two fractions with the higher percent inhibition compared to other factions are fraction 8 from ethyl acetate extract (FEA8) and fraction 3 from methanol extract (FM3). The IC50 values of FEA8, FM3 and acarbose are 16.370 \μg/mL, 59.042 \μg/mL, and 39.534 \μg/mL respectively. Conclusion: Fraction 8 from ethyl acetate extract of G. hombroniana leaves (FEA8) was separated and known in this study as the most bioactive \α-glucosidase inhibitor agent compared with another extract, fractions, and acarbose.

Enzyme, inhibiting carbohydrate metabolism and thereby decreasing glucose level is a class of drugs helpful in the management of type 2 Diabetes mellitus. Naturally existing \α-amylase and \α-glucosidase inhibitors from medicinally significant plants are shown to be effective in the management of postprandial hyperglycemia. In this investigation, leaf extract (BRLE), stem extract (BRSE), fruit extract (BRFRE) and flower extract (BRFLE) of Basella rubra were subjected to evaluate their antioxidant potential and their possible inhibitory effects on \α-amylase and \α-glucosidase. BRLE, BRSE, BRFRE, BRFLE (at concentration 100\μg/ml) exhibited 65.78, 56.84, 63.1, 61.03\% of \α-amylase inhibitory activity respectively with IC50 values of 71.66, 89.69, 73.68, 80.37 \μg/ml respectively. In the same way BRLE, BRSE, BRFRE, BRFLE (at concentration 100 \μg/ml) exhibited 97.63, 92.79, 82.17, 92.71 \% of \α-glucosidase inhibition with an IC50 value of 26.97, 28.53, 41.30, 38.80 \μg/ml respectively. Among the samples, the leaf extract of B. rubra registered higher content of total phenolics and flavonoids and also higher antioxidant activity in DPPH, nitric oxide and NBT radical scavenging assays. Though all the parts had shown potent inhibitory effects on \α-amylase and \α-glucosidase, the highest inhibitory potency was observed in the leaf extract of Basella rubra\ (p\<0.001).
