Wrigthia arborea (Dennst.) Mabb., locally known as Shet-kurchi, is a small deciduous tree. These species are important in the traditional healthcare, especially in menstrual and renal complaints. The present study was designed to investigate the antidiarheal and antidiabetic activities of methanol extract of W. arborea. The methanol extract was studied for antidiarrhoeal properties using castor oil and magnesium sulphate induced diarrhoeal model in mice. At the doses of 100 and 200 mg/kg body weight, the extract reduced the frequency and severity of diarrhea in test animals throughout the study period. Antidiabetic effect was also evaluated in normal and alloxan induced diabetic rats. Considerable drop of elevated blood glucose level was observed in the normoglycemic and alloxan induced diabetic rats at a dose of 150 and 300 mg/kg b.w. when the extract was given intraperitoneally. Altogether, these results suggest that the methanol extract could be used for treating diarrhea and diabetes. This is the first report of antidiarheal and antidiabetic potential of W. arborea.

The antioxidant and hypoglycemic capacities of various solvent fractions from the trunk-bark methanol extract of Terminalia alata Heyne ex Roth (T. alata) were investigated. The DPPH radical scavenging assay was used to evaluate the antioxidant activity, and the methods for determination of digestive enzymes inhibitory activity and fasting blood glucose reduction capacity in diabetic rats were used to determine the hypoglycemic activity of the extract fractions. The results indicated that higher total phenolics content was measured with increasing polarity of extraction solvent and DPPH radical scavenging activity coincided with phenolics content. Ethyl acetate fraction (EAF), n-butanol fraction (BF), and water fraction (WF) were obtained. They possessed α-amylase inhibition with the IC50 values of 0.056 ± 0.001, 0.138 ± 0.005, and 0.022 ± 0.001 mg.mL-1, respectively, which were lower than acarbose (IC50 = 0.154 ± 0.02 mg.mL-1). In contrast, IC50 values of α-glucosidase inhibitory activities of these fractions were higher than those of acarbose. In addition, these fractions also lowered fasting blood glucose concentrations in streptozotocin induced diabetic rats at a dose of 200 mg.kg-1 bw (body weight) without inducing body weight loss, which was not observed when treating with acarbose. The EAF and WF of trunk-bark of T. alata are recommended as potent sources for further research on antioxidant and hypoglycemic activities.

This study investigated the hypoglycemic and hypolipidemic effect of the oral administration of methanol extract of Hibiscus sabdariffa seed in alloxan induced diabetic albino rats. Two different doses (200 and 400 mg/kg) of the methanol extract of Hibiscus sabdariffa seed were administered daily to two groups of diabetic rats for a period of two weeks. Metformin (250 mg/kg) was given as the reference standard drug. Phytochemical, acute toxicity, fasting blood glucose, body weight, cholesterol, triglycerides and lipoproteins levels were determined using standard methods. Acute toxicity of methanol extract of Hibiscus sabdariffa seed was estimated to be greater than 5000 mg/kg body weight. There was an initial decrease in the body weight of the experimental animals after induction of diabetes which increased significantly (p<0.05) by the second week of treatment. The fasting blood glucose levels of the treated diabetic rats were significantly decreased at the second week of treatment with the group that received 400 mg/kg of extract recording the lowest fasting blood glucose level. The cholesterol, triglycerides and low density lipoproteins levels of the diabetic treated rats were significantly reduced while the high density lipoproteins level significantly increased. It can therefore be concluded that Hibiscus sabdariffa seed has the ability to lower blood sugar and maintain a stable lipid level.

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.

Aims: Arganimide A (4,4-dihydroxy-3,3-imino-di-benzoic acid) is a compound belonging to a family of aminophenolics found in fruit of Argania spinosa. The purpose of this study was to investigate the glucose and lipid lowering activity of Arganimide A (ARG A). Methods: The effect of a single dose and daily oral administration of Arganimide A (ARG A) on blood glucose levels and plasma lipid profile was tested in normal and streptozotocin (STZ) diabetic rats at a dose of 2 mg/kg body weight. Results: Single oral administration of ARG A reduced blood glucose levels from 26.50±0.61 mmol/L to 14.27±0.73 mmol/L (p<0.0001) six hours after administration in STZ diabetic rats. Furthermore, blood glucose levels were decreased from 5.35±0.30 mmol/L to 3.57±0.17 mmol/L (p<0.0001) and from 26.50±0.61 mmol/L to 3.67±0.29 mmol/L (p<0.0001) in normal and STZ diabetic rats, respectively, after seven days of treatment. Moreover, no significant changes in body weight in normal and STZ rats were shown. According to the lipid profile, the plasma triglycerides levels were decreased significantly in diabetic rats after seven days of ARG treatment (p<0.05). Moreover, seven days of ARG A treatment decreased significantly the plasma cholesterol concentrations (p<0.001). Conclusion: ARG A possesses glucose and lipid-lowering activity in diabetic rats and this natural compound may be beneficial in the treatment of diabetes.

Background: Corrigiola telephiifolia Pourr, is a perennial species, woody distributed throughout the north of Africa. This plant is used in traditional Mediterranean preparations and has many traditional uses especially treatment of diabetes. Aim/Methods: The current research was carried out to evaluate the antidiabetic effect of Aerial Parts of Aqueous Extract (APAE) of Corrigiola telephiifolia (C. telephiifolia) on both normal and streptozotocin (STZ)-induced diabetic rats treated at a dose of 5 mg/kg for fifteen days. Additionally, the histopathological changes in the liver, morphometric analysis, Oral Glucose Tolerance Test (OGTT) in normal rats and preliminary phytochemical screening for various components were realized. Results: Single oral administration of the APAE of C. telephiifolia (5mg/kg) showed no significant change in glycaemia of normal and STZ-induced diabetic rats. In contrast, repeated oral administration of C. telephiifolia reduced blood glucose levels from 4.11 ± 0.10 mmol/L to 3.16 ± 0.16 mmol/L (p<0.01) 15 days after administration in normal rats. Furthermore, blood glucose levels decreased from 17.84 ± 1.75mmol/L to 1.93 ± 0.33 mmol/L (p<0.0001) in STZ diabetic rats after fifteen days of treatment. According to the oral glucose tolerance test, C. telephiifolia (5 mg/kg) was shown to prevent significantly the increase in blood glucose levels in normal treated rats 30 min after glucose administration when compared to the control group. Also, the liver architecture of diabetic rats treated by C. telephiifolia was improved when compared with the liver architecture of untreated diabetic rats. Concerning the preliminary phytochemical screening of C. telephiifolia, several compounds have been found such as polyphenols, flavonoids, saponins, mucilage and terpenoids. Conclusion: The results show that the aqueous extract of C. telephiifolia possesses significant antihyperglycemic activity.

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

Postprandial hyperglycemia is a predisposing factor for vascular dysfunction and organ damage.α-glucosidase is a hydrolytic enzyme that increases the glucose absorption rate and subsequently elevates blood glucose levels. Garlic (Allium sativumL.) is a rich source of several phytonutrients, including thiosulfinate (THIO). The aim of this study was to evaluate the ability of THIO, a potent inhibitor of intestinalα-glucosidase, to reduce postprandial blood glucose. Male albino rats were randomly assigned to five different groups (n=10/group). Group 1 served as the control group. Groups 2–5 were injected intraperitoneally with a single dose of streptozotocin (STZ) to induce diabetes. Group 2 comprised untreated diabetic rats. Groups 3 and 4 contained diabetic rats that were given THIO orally (20 mg/kg body weight/day and 40 mg/kg body weight/day, resp.). Group 5 was the positive control having diabetic rats treated orally with acarbose (10 mg/kg body weight/day; positive control). Diabetic rats treated with THIO displayed a significant blood glucose reduction (p<0.001and < 0.01 by analysis of variance, resp.) and a significant elevation in insulin compared with that of untreated rats. THIO is an effective noncompetitive intestinalα-glucosidase inhibitor that promotes hypoglycemic action (p<0.001) in STZ-injected rats. THIO is a promising agent for the management of postprandial hyperglycemia.

Background: The anti-hyperglycemic potential of methanol stem bark extract of Anacardium occidentale (MSBEAO) was investigated using an alloxan-induced diabetic rat model. Alloxan administration induces the generation of free radicals which can affect antioxidant status resulting in the disruption of the β-cells of the pancreas. Therefore, this study examines the antioxidant potential of the plant extract and the ameliorating effect on the pancreas of alloxan-induced diabetic rats. Methods: Diabetes was induced by intraperitoneal injection of 150 mg/kg body weight of alloxan monohydrate. MSBEAO, at a concentration of 100 or 200 mg/kg b.w. was orally administered to alloxan-induced diabetic rats and normal rats. The hypoglycemic effect, oral glucose tolerance test, and biochemical assay of alloxan-induced diabetic rats were assayed using standard procedures. Results: Preliminary phytochemical screening of the extract revealed the presence of alkaloids, tannins, saponins, terpenoids, carbohydrates, and phenols at moderate concentrations. The lethality dose (LD50) of the plant extract was found to be equal to or less than 5000 mg/kg b.w. The hypoglycemic effect of the extract on the non-diabetic rats revealed a significant (p<0.05) decrease in the blood glucose concentration of animals administered with 1 g/kg b.w. of the extract, compared to normal control rats administered with normal saline. In the oral glucose tolerance test, the methanol extract exerted the highest response, similar to glibenclamide after 15 and 30 minutes of administration, compared to the control rats. The methanol extract yielded the highest blood glucose lowering effects after 9 days of treatment (p<0.05), compared to diabetic rats administered with normal saline and 0.3 mg/kg b.w. of glibenclamide. Administration of the extract at 200 mg/kg b.w. showed improved pancreas architecture and regeneration of the β-cells, compared with the pancreas of animals in the other groups. Conclusion: The results of this study suggest that MSBEAO is a potentially effective agent for the management of diabetes which might result from the antioxidant-generating capacity of the stem bark.
