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.

Abstract Background Diabetes mellitus is a serious complex multifactorial disorder that imposes huge health and economic burden on societies. Because the currently available medications have many drawbacks, it's important to look for alternative therapies. Medicinal plants utilized in folk medicine are ideal candidates. Therefore, this work assessed the antidiabetic action of n-butanol extract from the whole plant Atractylis flava Desf (BEAF). These ethnomedicinal properties of BEAF were scientifically validated using in vitro and in vivo assays. In vitro antidiabetic effect of the BEAF was conducted using α-Glucosidase and α-Amylase assays. While the antihyperglycemic activity was assessed using two rat models: Alloxan-induced diabetic rats and oral glucose challenged rats. Experimental diabetes was induced by a single intraperitoneal injection of alloxan at a dose of 150 mg/kg and animals with fasting blood glucose levels (BGL) > 200 mg/dL were considered diabetic. Glibenclamide (5 mg/kg) was used as a typical drug. Results The BEAF at all tested dose levels (100, 250, and 500 mg/kg) showed a significant decrease in blood glucose level in all the two animal models. Besides, the plant extract exhibited a potent inhibitory effect on α-Amylase and α-Glucosidase activity at a concentration of 1000 µg/mL with 76.17% and 89.37%, respectively. Conclusion BEAF exerts in vitro and in vivo antidiabetic effects, these results suggest that the plant extract can be a therapeutic resource in the treatment of diabetes and hyperlipidemia.

The purpose of current investigation was to investigate in vivo and in vitro anti-diabetic potentials of aqueous extract of Alphonsea sclerocarpa leaves against alloxan induced diabetes in albino rats. Two in vivo and one in vitro methods were performed for the evaluation of aqueous extract for antidiabetic activity. For in-vivo evaluation, diabetes was induced in albino rats by administering a single dose of alloxan. The study was designed to test the acute effect of aqueous extract of Alphonsea sclerocarpa (AEAS) to reduce blood glucose in OGTT. The chronic study of 21 days was performed against diabetic rats and blood glucose was determined at 1st , 7 th, 14th and 21st day. In chronic in vivo study, serum parameters insulin, urea, creatinine, total cholesterol, triglycerides, ALT and AST were also estimated at 21st day to determine the effects of aqueous and aqueous extracts on complications of diabetes mellitus. Glucose uptake by hemidiaphragm assay was performed to test the ability of extract to utilize glucose. In Oral Glucose Tolerance Test, standard glibenclamide and aqueous extract (200mg/kg and 400mg/kg) treated animals have shown significant reduction in blood glucose at 90 mins but at 120 mins. In chronic model the aqueous extract effectively reduced blood glucose levels (P<0.001) at 14th and 21st day of study in therapeutic groups and effect was comparable to that of standard. The extract could also significantly (P<0.001) reduce concentrations of SGOT, triglycerides, cholesterol and urea in serum and significantly (P<0.001) increased the insulin level in blood which proves beneficial effects of the extract in diabetes. The change in concentrations of SGPT and urea were less significant (P>0.01). The presence of extract in glucose uptake assay could significantly increase utilization of the glucose by rat hemidiaphragm. The aqueous extract of Alphonsea sclerocarpa possess significant antidiabetic properties against alloxan induced diabetic animals.

This study investigated the in-vitro antioxidant activity and antidiabetic effect of Muntingia calabura fruit extract by in-vitro α-amylase and α-glucosidase inhibitory activity. Muntingia calabura fruit was extracted with aqueous methanol by soxhlet extraction. The total phenols and total flavonoids contents were estimated and evaluated for antioxidant activities (DPPH, ABTS) and in-vitro antidiabetic activity by measuring their inhibitory activity on α-amylase and α-glucosidase levels. The findings showed that the fruit extract had high content of total phenol and exhibited moderate free radical scavenging activity. The fruit extract showed inhibitory effect on α-amylase [IC50Value =61.43 μg/mL] and α-glucosidase [IC50 Value=140.33 μg/mL] compared to standard acarbose. The fruit extract can be used as a potential source for the development of new hypoglycemic agents may be due to the presence of high phenol content.

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.

Argan Oil

The Argan tree (Argania spinosa. L) is an evergreen tree endemic of southwestern Morocco. For centuries, various formulations have been used to treat several illnesses including diabetes. However, scientific results supporting these actions are needed. Hence, Argan fruit products (i.e., cake byproducts (saponins extract) and hand pressed Argan oil) were tested for their in-vitro anti-hyperglycemic activity, using α-glucosidase and α-amylase assays. The in-vivo anti-hyperglycemic activity was evaluated in a model of alloxan-induced diabetic mice. The diabetic animals were orally administered 100 mg/kg body weight of aqueous saponins cake extract and 3 mL/kg of Argan oil, respectively, to evaluate the anti-hyperglycemic effect. The blood glucose concentration and body weight of the experimental animals were monitored for 30 days. The chemical properties and composition of the Argan oil were assessed including acidity, peroxides, K232, K270, fatty acids, sterols, tocopherols, total polyphenols, and phenolic compounds. The saponins cake extract produced a significant reduction in blood glucose concentration in diabetic mice, which was better than the Argan oil. This decrease was equivalent to that detected in mice treated with metformin after 2–4 weeks. Moreover, the saponins cake extract showed a strong inhibitory action on α-amylase and α-glucosidase, which is also higher than that of Argan oil.

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
