Diabetes mellitus is one of the largest global health problems demanding preventive and new therapeutic interventions. Currently, there is a need for safe, effective, and less costly antidiabetic medications, and investigating medicinal plants for new antidiabetic medication is an interesting research area. Thus, the present study was done to evaluate the antidiabetic activities of 80% methanolic leaf extract of Calpurnia aurea (Ait.) Benth. subspecies aurea (Fabaceae) in mice. Hypoglycemic and antihyperglycemic activity of the three doses (100mg/kg, 200 mg/kg, and 400 mg/kg) of crude hydromethanolic leaf extract was studied on normoglycemic, oral glucose loaded, and streptozotocin-induced diabetic mice models. The effect of the extract on body weight and diabetic dyslipidemia was also studied on streptozotocin-induced diabetic mice. Glibenclamide (5 mg/kg) was used as a standard drug in all cases. A glucose meter and an automated chemistry analyzer were used to measure blood glucose and serum lipid level respectively. Data were analyzed using one-way analysis of variance followed by Tukey’s post hoc multiple comparison test. All the three doses of the plant extract (100mg/kg, 200 mg/kg, and 400 mg/kg) showed a significant (p<0.05) antihyperglycemic activity in the diabetic mice at the 7th and 14th day of repeated daily dose administration as compared to the negative diabetic control. But, the extract did not show significant blood glucose lowering activity in normoglycemic, oral glucose loaded, and diabetic mice after single dose administration, and it did not significantly improve the body weight loss and diabetic dyslipidemia of diabetic mice after repeated daily dose administration for 14 days. This study revealed that the hydromethanolic extract of Calpurnia aurea leaves possesses significant antihyperglycemic activity justifying the traditional use of the plant for diabetes.

Background: Diabetes mellitus is a metabolic disorder associated with relative or absolute insulin deficiency or resistance, characterized by hyperglycemia. Modern prescriptions such as pioglitazone have better therapeutic potential, but its side effects and financial burden for developing countries have motivated the researchers to find alternative natural drugs to compete hyperglycemia in patients with diabetes. The present study was conducted to explore the therapeutic potential of selected medicinal plants for the treatment of diabetes as an alternative to allopathic medicines. Method: In present study, hydroalcoholic extracts of Curcuma longa, Lavandula stoechas, Aegle marmelos, and Glycyrrhiza glabra and their polyherbal preparation (PHP) as compound drug were investigated for their antihyperglycemic potential in alloxan-induced diabetic mice. The study subjects (mice) were divided into different groups as normal control, diabetic control, pioglitazone treated (standard drug), test groups (plant extract treated 50, 100, and 150 mg/kg body weight), and PHP-treated group. Blood glucose concentration of all the study animals was determined by Glucose strip test. Qualitative phytochemical analysis of all the plant extracts was also performed following standard methods. Result: It was investigated that treatment of alloxan-induced diabetic mice with hydroalcoholic extracts of studied medicinal plants showed significant ( P < .05) effects on fasting blood glucose levels (from baseline to normal range) in a manner comparable to that of the reference drug, pioglitazone (1 mg/kg body weight intraperitoneal). The tested plant extracts significantly ( P < .05) reduced the glucose concentration in blood of diabetes-induced mice in a dose-dependent manner. Conclusion: It could be concluded that studied medicinal plants have antihyperglycemic activity. The study findings favor the use of traditional herbal medicinal practices for the management of diabetes that might due to the presence of bioactive phytoconstituents in plants. However, larger studies are required to identify, isolate, and characterize the bioactive phytoconstituents responsible for antihyperglycemic activity of studied medicinal plants.

Background and objectives: Anwar Ratol is one of the most famous cultivar of mango in South Asia, especially Pakistan. Mango leaves are left as food waste. This study evaluated the potential of mango (Anwar Ratol) leaves for their use against diabetes mellitus. Material and Methods: In this study, hydro-alcoholic extract of the plant leaves was prepared and evaluated by electrospray ionization mass spectroscopy (ESI-MS) and high-performance liquid chromatography (HPLC) for the presence of phytochemicals. The plant extract was administered to Alloxan induced diabetic mice followed by evaluation through oral glucose tolerance test; determination of postprandial glucose, body weight, lipid profile and histopathological evaluation of pancreas. Results: Chemical evaluation revealed the presence of mangiferin, rhamnetin, catechin, epicatechin, iriflophenone 3-C-β-D-glucoside, gallic acid and other phenolic and flavonoid compounds. The plant extract exhibited a decrease in postprandial blood glucose following seven days therapy in diabetic mice. The extract also prevented the rise in blood glucose level as determined by glucose tolerance test in diabetic mice. Furthermore, therapy of diabetic mice with the extract prevented a decrease in body weight and decline in beta-cell mass associated with alloxan and improved lipid profile. Conclusion: The findings of the study clearly suggested that the leaf extract of the plant might possess anti-diabetic activity possibly due to the presence of mangiferin and other phytochemicals such as phenolic and flavonoid compounds. This study will serve as a basis for the use of mango leaf extract against diabetes. Furthermore, this study will also provide basis for the bioassay-based fractionation and isolation of active principles responsible for the antidiabetic potential of mango leaves.

The present study was designed to test whether the precursor of serotonin (i.e.5-HTP) and dopamine (i.e. L-DOPA) can influence Body weight and certain hematological constitutes (i.e. blood glucose, glycosylated hemoglobin and serum protein) in streptozotocin induced diabetic mice. In the study, animals were divided into 6 groups. After 10 days at the termination of experiment body weight and blood glucose taken. Blood was collected from left ventricle and deposited to pathology for haematological analysis (i.e. blood Glucose, glycosylated heamoglobin, serum protein, triglyceride total cholesterol, HDL-cholesterol, LDC-cholesterol, and VLDL-cholesterol). Statistical analysis were done with the help of student’s ‘t’ test followed by analysis of variance (ANOVA). The result of the present study suggest that peripheral administration of 5-HTP (a precursor of serotonin) and L-DOPA (a precursor of dopamine) influences the body weight gain and lipid profile (i.e. triglyceride, total cholesterol, HDL-cholesterol , LDL-Cholesterol, VLDC-cholesterol) in streptozotocin induce diabetic mice. The finding of the present study supports the concept that insulin alone does not fully control diabetes. Other chemical substance like neurotransmitter/hormones may involve in controlling the diabetes.

Purpose: To investigate Heliotropium strigosum whole plant extract for its potential to reduce the blood glucose level of alloxan-induced diabetic mice.Methods: Preliminary phytochemical analysis was carried out using standard  procedures. Diabetes was induced in Balb/c mice by injecting alloxan (200 mg/kg i.p.). The crude methanol extract of Heliotropium strigosum (Hs.Cr, 30, 100 and 300 mg/kg doses) was administered daily to alloxan-induced diabetic mice for 15 days and its effect on fasting blood glucose levels, body weight and oral glucose tolerancewas evaluated. Two control groups (non-diabetic control and diabetic control)  received normal saline (0.2 ml). Metformin (500 mg/kg) was used as reference standard.Results: Heliotropium strigosum showed positive for the presence of alkaloids, tannins and flavonoids. The extract (30, 100 and 300 mg/kg) caused significant reduction in the fasting blood glucose level of alloxan-induced diabetic mice on days 5, 10 and 15 compared to diabetic control (p < 0.001). In this regard, the  anti-hyperglycemic effect compared to the reference (metformin). The extract also timedependently decreased the body weight of the treated animals as well as improved tolerance of the oral glucose overload.Conclusion: These results indicate that Heliotropium strigosum possesses  anti-hyperglycemic effect, reduces body weight and enhances the tolerance of  glucose overload in mice. Further studies are therefore required to determine its  feasiilty as an alternate herbal medicine in the management of diabetes in humans.Keywords: Heliotropium strigosum, Anti-hyperglycemic, Alloxan-induced diabetic mice, Blood glucose, Oral glucose tolerance, Body weight

Glucose Reduction

The leaf latex of Aloe pulcherrima has been used as remedy for diabetes mellitus. This was carried out to determine in vitro and in vivo antidiabetic activities of the leaf latex of Aloe pulcherrima. Methods. Sucrase and maltase inhibitory activity of the leaf latex of A. pulcherrima was determined in glucose oxidase assay, and α-amylase inhibitory activity was determined in dinitrosalicylic acid assay. Normoglycemic, glucose-loaded, and streptozotocin-induced diabetic mice were treated orally to determine blood glucose lowering activity of the latex. Effect of the latex on serum lipid level and body weight was measured in streptozotocin-induced diabetic mice. Additionally, DPPH assay was used to determine free radical scavenging capacity of the latex. Results. Antioxidant activity of the latex was concentration dependent; the strongest inhibition was measured at 800 μg/ml (80.57%). The leaf latex of A. pulcherrima inhibited sucrase (IC50 = 2.92 μg/ml), maltase (IC50 = 11.81 μg/ml) and α-amylase (IC50 = 14.92 μg/ml) enzymes. All doses of the leaf latex induced hypoglycemic effect after 4 h in normal mice, and low dose of the latex did not show significant effect after 6 h. Glucose reduction of the leaf latex of A. pulcherrima was significant (p<0.05) in oral glucose-loaded mice compared to the vehicle control. Blood glucose level of diabetic mice was significantly (p<0.05) reduced on week one and weak two in a streptozotocin-induced diabetic mouse model. Glucose reduction increased with increasing the doses of the leaf latex of A. pulcherrima on week one (p<0.05 (200 mg/kg), p<0.01 (400 mg/kg), and p<0.001 (600 mg/kg)). Administration of the leaf latex of A. pulcherrima for two weeks significantly (p<0.05) improved diabetic dyslipidemia and body weight of diabetic mice. Conclusion. The study confirmed that the leaf latex of the plant showed a significant antidiabetic activity justifying the traditional uses of the plant.

The objective of present study was to analyze and compare the nephroprotective effects of petroleum ether extracts of seeds of Nigella sativa and Silybum marianum in Swiss albino mice. Petroleum ether extracts of seeds of Nigella sativa and Silybum marianum were administered (200 mg kg–1) orally for 14 days following one dose of cisplatin injection (16 mg kg–1 i.p.) on 4th day. Cisplatin toxicity was identified in mice by loss of body weight, reduced triglycerides levels, elevated blood glucose, blood urea nitrogen and creatinine levels (P < 0.05). Silybum marianum and Nigella sativa significantly enhanced the body weight (9%) of diabetic rats. Silybum marianum had significantly reduced the elevated blood glucose (–106%), and BUN levels (–9%) as compared to the Nigella sativa administration. Silybum marianum extract also significantly elevated the levels of triglycerides (257%) which were much reduced after the cisplatin injection. Histological study showed that the cisplatin treated group demonstrated the necrosis signs in the glomerulus of Bowman’s capsule, hyalinization and severe cellular damage. The animals administered with extracts showed nearly normal kidney architecture, however, the kidney tissues of Silybum marianum-treated animals showed some improvement with slight signs of cellular damages.

Aim. The efficacy of triphala on lipid profile, blood glucose and anthropometric parameters and its safety were assessed. Methods. Databases such as PubMed, ScienceDirect, Web of Science, and Thai Library Integrated System (ThaiLIS) were systematically searched to review current evidence of randomized controlled trials (RCT) on triphala. RCTs investigating the safety and efficacy of triphala on lipid profile, blood glucose and anthropometric parameters were included. Study selection, data extraction, and quality assessment were performed independently by 2 authors. Results. Twelve studies on a total of 749 patients were included. The triphala-treated groups showed significantly reduced low-density lipoprotein-cholesterol, total cholesterol and triglyceride in 6 studies. Five RCTs demonstrated triphala-treated groups led to statistically significant decrease in body weight, body mass index and waist circumference of obese patients. Moreover, triphala significantly decreased fasting blood glucose level in diabetic patients but not in people without diabetes. No serious adverse event associated with triphala was reported during treatment. Conclusions. This review summarized a current evidence to show triphala might improve the lipid profile, blood glucose, the body weight, body mass index and waist circumference under certain conditions. However, large well-designed RCTs are required to confirm this conclusion.

The crude methanol extract of Gouania tiliaefolia Lam. was partitioned by the modified Kupchan method and the fractions were evaluated for total phenolic content, antioxidant, cytotoxic, thrombolytic, hypotonic and heat-induced membrane stabilizing activities. The petroleum ether soluble fraction (PESF) and methanol extract (ME) showed the highest phenolic content of 78.30 ±1.60 mg and 70.37 ± 0.84 mg, respectively, which were expressed in gallic acid equivalent (GAE). Similar trends were observed in case of anti-oxidant and cytotoxic activities, where the PESF possessed the highest free radical scavenging activity and brine shrimp lethality (IC50 = 2.88 ± 0.02 μg/ml, LC50 = 2.59 ± 0.14 μg/ml), followed by ME (IC50 = 4.79 ± 0.17 μg/ml, LC50 = 3.38 ± 0.08 μg/ml) and CSF (IC50 = 37.51 ± 0.96 μg/ml, LC50 = 73.55 ± 0.26 μg/ml). In case of assays for thrombolytic and membrane stabilizing activities, all extractives showed insignificant results compared to the respective standards. The crude methanol extract of G. tiliaefolia was used to examine the in-vivo analgesic (central and peripheral), antidiarrheal and antidiabetic activities in Swiss albino mice. In case of castor oil induced diarrhea, the ME gave better reduction of diarrhea by 71.43% (at 400 mg/kg-body weight) compared to loperamide (64.29%). Antidiabetic activity was evaluated by oral glucose tolerance test and the ME showed 71.42% and 75.39% reduction of blood glucose at doses 200 and 400 mg/kg-body weight, respectively when compared with the standard glibenclamide that reduced blood glucose by 66.17%. The central- and peripheral-analgesic activity was evaluated by the tail-flick test and acetic acid induced writhing test, respectively. In both the cases, ME demonstrated dose-dependent analgesic activity compared to the standards. Bangladesh Pharmaceutical Journal 22(2): 200-207, 2019
