Adenosma bracteosum Bonati. (A. bracteosum) has been used in traditional and modern medicine in Vietnam for curing hepatitis. In this study, ethanol and aqueous extracts of A. bracteosum were evaluated for their α-glucosidase inhibitory activities and anti-hyperglycemic effects on glucose loaded hyperglycemic and streptozotocin (STZ) induced diabetic mice. The α-glucosidase inhibition of the extracts was evaluated by colorimetric assays, and the anti-diabetic activity was tested on a STZ-induced diabetic mice model. The ethanol and aqueous extracts showed a significant α-glucosidase inhibitory activity, which was more effective than acarbose at the same concentration. In the STZ-induced diabetic mice, both extracts showed a strong anti-hyperglycemic activity, with the group receiving 50 mg/kg of ethanol extract and the group receiving 50 mg/kg of aqueous extract presenting 64.42% and 57.69% reductions, respectively, in the blood glucose levels when compared with the diabetic control group, on day 21 (p > 0.05). Isoscutellarein-8-O-β-D-glucopyranoside (IG) was identified from the ethanol extract, which showed a strong inhibitory activity against α-glucosidase, with a ten times higher potency compared with the positive control acarbose. The anti-hyperglycemic effect of IG was effectively similar to the standard drug, glibenclamide, at the same dose of 10 mg/kg (p > 0.05). These results indicated that A. bracteosum has a great antidiabetic potential.

Antiplasmodial and analgesic effects of crude ethanol extract ofPiper guineensewas investigated in mice. The antiplasmodial and analgesic efficacy of the extract was judged on its ability to reduce parasitemia and writhing, respectively, in mice. The antiplasmodial screening involved treating infected mice with 200, 400, and 600 mg/kg body weight of extract while the positive control group was given standard artesunate drug. The analgesic test was carried out by administering 1000, 1500, and 2000 mg/kg body weight of extract to three groups of healthy mice, respectively, after induction of pain with 0.75% acetic acid. The positive control group was given aspirin drug. Parasitemia was reduced by 28.36%, 43.28%, and 62.69% in a dose-dependent pattern in the curative test which was significantly different (P<0.05) from 96.03% of the standard drug. The reduction of writhing by mice given the extract was also dose-dependent (36.29, 45.43, and 59.07%). Aspirin drug was however more effective (86.36%). The extract was safe at 2000 mg/kg body weight. Phytochemical screening revealed the presence of flavonoids, tannins, phlobatannins, terpenoids, and coumarins. Result obtained in this study demonstrated the efficacy of ethanol extract ofPiper guineenseas an antiplasmodial and analgesic agent.

Antidiabetic activity of Vernonia amygdalina and its possible synergism with glibenclamide was checked. Forty eight rats were used for the research, for hypoglycermic study of V. amygdalina alone, they were grouped into five of six rats each. Group 1 was the negative control and was administered distilled water orally. Groups 2, 3, and 4 were the treatment groups which received 100, 200 and 300 mg/kg body weight of the V. amygdalina extract respectively orally by intubation. Group 5 was the positive control group which received a known antidiabetic drug, glibenclamide. Diabetes was induced with alloxan. For the synergism study, another 18 rats grouped into 3 of six rats each was used. Both groups of glibenclamide only and glibenclamide plus V. amygdalina extract were dosed for 14 days orally by intubation, thereafter were sacrificed and blood collected from heart for analysis. There were 5 replicates grouped by weight throughout the study and both single and synergistic studies had the same controls. Effect of V. amygdalina extract was checked on blood glucose and its possible synergism with glibenclamide. All results in treatment groups were compared with the normal control at statistical confidence of p<0.05. Result shows that V. amygdalina extract reduced blood glucose level in the test groups as dose of extract increased. Combination of V. amygdalina with glibenclamide demonstrated further deduction in blood glucose levels in the treatment rats groups. Therefore addition of V. amygdalina into glibenclamide increased efficacy in the diabetic rats. The interaction between V. amygdalina and glibenclamide in this work was additive and therefore synergistic.

Diabetes mellitus is a metabolic disorder disease characterized by increased blood glucose levels due to impaired insulin secretion or increased insulin resistance. The study was performed to investigate the blood glucose lowering effect of Musa acuminata Colla fruit peel (MACFP) ethanol extract in experimentally induced diabetic rats. 25 rats were divided into five groups, i.e negative control group (0.5% NaCMC), positive control group (glibenclamide), and treatment group of MACFP ethanol extract with dose 250, 375, and 500 mg/kg body weight (mg/kg BW). The blood sample was taken from the lateral vein of the tail, and then blood glucose level was observed on 0, 30, 60, 90, and 120 minutes. The results provide information that MACFP ethanol extract with dose 250, 375, and 500 mg/kg BW have the same effect with a positive control (glibenclamide) in lowering blood glucose level on diabetic rats (p>0,05). MACFP ethanol extract with dose 500 mg/kg BW had the highest percentage of decrease in blood glucose level (42,62%), followed by doses 375 mg/kg BW (37,26%) and 250 mg/kg BW (24,12%).

Objective: Okra (Abelmoschus esculentus (L.) Moench) has potential antidiabetic activity. This study created a nanoemulsion of okra extract (NOE) and examined its activity on alloxan-induced diabetes mellitus in mice. Methods: Okra was macerated with 70% ethanol and dried in a rotary evaporator into the crude extract. The extract was encapsulated in a solution of glyceryl caprylate, propylene glycol, and glycerine to form a nanoemulsion. To determine the antihyperglycaemic effect of okra extract, 35 male mice (Mus musculus L.) were divided into seven groups: a non-diabetic normal control group and six diabetic mice groups (untreated negative control, glibenclamide-treated positive control, and four treatments with okra ethanol extract (OEE) at 200 and 400 mg/kg BW and NOE at 200 and 400 mg/kg BW). Results: The group treated with NOE at 400 mg/kg BW (NOE400) had the lowest average blood glucose level of 93.4 mg/dL among hyperglycaemic mice. The decrease in blood glucose levels in NOE400 (52.05%) was significantly different from those in the positive control (42.63%) and OEE treatments (39.32%). The nanoemulsion used in this study fulfills quality requirements, with a mean particle size of 134.7 nm, a polydispersity index of 0.512, and a zeta value of −26.72 mV. Conclusion: NOE reduced blood glucose levels in alloxan-induced hyperglycaemic mice better than OEE. Nanoemulsion can improve the antidiabetic activity of okra extract by increasing penetration of active compounds into interstitial space so that their delivery and bioavailability are higher.

Aims: Presently the medicinal world is rapidly turning more on the therapeutic health benefits of natural product and medicinal plants in the management of major crucial disease and their complications. Medicinal plant, Stephania japonica has been studied for exploring antidiabetic potentiality as an alternative source of medicine against the global threat of Diabetes mellitus (DM). Methods: The extraction of S. japonica leaf was carried out by acetone and ethanol. Phytochemical screening and quantitative analysis of S. japonica leaf extracts were evaluated through chemically forming characterized color formation and calibration method respectively, by using standard reference substances (ascorbic acid, gallic acid, and quercetin) to assess the probable compounds present in the extract. Anti-diabetic potentiality of highest phytochemicals containing two extracts were investigated in in vitro as a ⍺-amylase inhibitors and in vivo through alloxan-induced Swiss albino diabetes mice model. Results: Alkaloids, carbohydrates, steroids, flavonoids, resins, saponins, tannins and coumarins were present in the leaf extracts. The estimated amount of total phenolics, flavonoids, flavonols and proanthrocyanidins contents of acetone and ethanol extract were 92.12±0.64 and 56.54±1.05 mg of gallic acid equivalent (GAE)/gm of dry extract, 66.02±1.42 and 46.17±0.54 mg of catechin equivalent (CAE)/gm of dry extract, 7.05±0.108 and 5.26±0.083 mg of quercetin equivalent (QUE)/gm of dry extract, 35.19±0.67 and 9.55±1.11 mg CAE/gm of dry extract, respectively. In 3, 5-dinitrosalicylic acid method, acetone and ethanol extract showed α-amylase inhibition of 51.02% and 46.62%, respectively at the concentration of 1000 µg/mL whereas in starch iodine color assay, acetone and ethanol extract showed inhibition of 57.32% and 52.12%, respectively at the concentration of 800 µg/mL. In contrast, both of the leaf extracts significantly (p<0.05 to p<0.001) improved the lipid profile parameters, blood glucose level and serum hepatic marker proteins in alloxan-induced diabetic mice. Conclusion: The present study strongly concluded that S. japonica leaf extracts process potent antidiabetic potentiality that might be significance for the management of diabetes and its complications.

Background: Nowadays obesity recognized as chronic or non-communicable disease. Pathophysiology of obesity caused by an imbalance between energy intake and expenditure. Obesity was known to be a risk factor for the development of metabolic syndrome. The aim of this study is to evaluate activity of ethanol extract of red spinach (EERS) to prevent obesity in diet-induced zebrafish. Materials and Methods: Acclimatization period for zebrafish was carried out for 2 weeks. After the acclimatization, zebrafish were divided into 6 groups (n = 10 in each group) such as normal group (negative control); obese group (positive control); standard drug (orlistat 4,5 µg/ml); EERS group (50 µg/ml); EERS group (100 µg/ml); and EERS group (200 µg/ml). During a period of 4 weeks, normal group received a standard diet and didn’t received EERS administration. Positive control group received Artemia. Treated group received Artemia and were combined by administration of EERS. To determine obesity criteria we calculated of zebrafish BMI. Results: Based on BMI calculation, EERS 50 µg/ml, 100 µg/ml and 200 µg/ml showed a preventive effect on obesity compared to the positive control group. In addition, EERS 50 µg/ml was able to reduce BMI lower than the other extract groups. Conclusion: It can be concluded that EERS 50 µg/ml has strength preventive effect on diet-induced obese zebrafish. This effect might be influenced by the presence of phytochemical compounds of extract such as flavonoid, saponins, and tannins.
