Introduction: Diabetes mellitus is a metabolic disorder, which affects many people throughout the world. The inefficacy and multiple side effects of most synthetic anti-diabetic drugs are reported by various studies. Thus, many researchers are focused on the use of medicinal plants as safe and potent anti-hyperglycemic drugs. The aim of this study is the evaluation of the effect of Afghan senjed (Elaeagnus Angustifolia L.) leaves aqueous alcoholic extract on blood glucose level of diabetic rats. Methods: Rats were divided into 6 groups: normal, diabetic, metformin and Elaeagnus Angustifolia leaves extract (EALE) groups, which received 200, 400 and 800 mg/kg doses of extract for 15 days. Diabetes was induced by single dose intraperitoneal administration of streptozotocin (STZ). During treatment, the effect of single and repeated oral administration of EALE on blood glucose level of diabetic rats was evaluated. On last day, the effect of EALE on oral glucose tolerance test (OGTT) was also assessed. Results: All doses of EALE showed significant reduction in blood glucose level, an improvement of glucose tolerance and enhancement in body weight. Conclusion: EALE possessed an antihyperglycemic property in diabetic rats.

Background: The high polyphenol content of white tea exhibits antiseptic and antioxidant properties that can prevent free radicals, inhibit oxidative stress and inflammation associated with various diseases such as obesity, diabetes and other degenerative diseases. Oral administration of white tea ethanolic extract (WTE) is expected to use as an alternative in the treatment of diabetes mellitus. Objective: This study aims to evaluate the effect of WTE on reducing fasting blood glucose levels in diabetic rats. Methods: Antidiabetic activity study of white tea extract performed on diabetic Sprague-Dawley male rats induced streptozotocin-nicotinamide for 14 days of oral administration. The antidiabetic effect compared to normal control, diabetic control, and standard control groups. Results: The administration of WTE for 14 days showed decreased fasting blood glucose level in diabetic rats. The dose of 100 mg/kg BW of WTE has the highest effect on reducing fasting glucose level significantly compared to negative control group (p\<0.05). The content of flavonoids, especially catechin compounds are suspected to play a role in lowering fasting blood glucose levels. Conclusion: The administration of WTE for 14 days has potentially antidiabetic activity in diabetic rats induced streptozotocin-nicotinamide.

Background: Nigella sativa L. (Black seed), is commonly used by traditional healers as a remedy for more than four thousand years. The antidiabetic property of N. sativa seeds oil is attributable to the presence of Thymoquinone (TQ). On the other hand many studies have been designed to investigate the possible effects of the TQ in Streptozotocin (STZ) and nicotinamide (NA)-induced diabetes in rats. Aim of the study: The aim of this study was to elucidate the mechanisms underlying the glucose lowering effects of thymoquinone. Methods: In vitro and in silico using glycogen phosphorylase (GPa) enzyme assay and docking tools were used. Results: Oral administration of TQ for 60 days, dose dependently improved the glycemic status in STZ-NA induced diabetic rats. GPa activity was measured in the direction of glycogen synthesis by the release of phosphate from glucose-1-phosphate. TQ at a concentration of 0.05 Mm inhibits GPa activity by only 14.9\%. Conclusion: These results show that TQ at 60 mg/kg b.w is associated with potential antihyperglycemic effects. Furthermore, anti-diabetic properties of TQ are unassociated with glycogen phosphorylase inhibition.

Objectives: Present study investigated the effect of hydro-methanolic extract of seed of Swietenia mahagoni (HMESM) on a-glucosidase inhibition in normal and streptozotocin-induced diabetic rats. Methods: Oral carbohydrate tolerance tests were performed in 16h fasted normal and diabetic rats loaded with starch or sucrose or glucose at the dose of 3g/kg, 15min after administration of 250 (S1), 500 (S2), 1000 (S3) mg/kg of HMESM, vehicle (control),or pretreatment at the dose of 10 mg/kg of acarbose (Acar). Blood samples were analyzed for glucose levels at 0, 30th, 60th, and 120th min after respective treatments and the peak blood glucose (PBG) levels and area under the curves (AUC) were determined. Results: Results demonstrated that 500 mg, 1000 mg/kg of HMESM reduced and prolonged the PBG and decreased AUC simultaneously after starch and sucrose loading in normal and diabetic rats. Similarly acarbose also reduce the sucrose and starch induced blood glucose excursion, whereas it had no peak blood glucose suppressive effect after exogenous glucose load in both normal and diabetic rats. On the other hand, phytochemical study of the said extract revealed that it is rich in phenolic compounds (46.25 mg of gallic acid equivalent/g of extract) and flavonoids (231.72 mg of quercetin equivalent/g of the extract), which may may responsible for pharmacological activities. Conclusion: The HMESM may have PBG suppressive effect in post-carbohydrate challenged state as evidenced by reduced PBG and AUC. This suggest that HMESM may be used effectively as a safer alternative to control postprandial hyperglycemia especially in pre-diabetic and diabetic patients.

Background: Plant extracts are generally assumed to be more acceptable and less hazardous than synthetic compounds and could be alternative antidiabetic treatments. Portula caoleracea has been used as one of the traditional edible and medicinal plant in Algeria to treat diabetes. The aim of the present study was to determine the effects of lyophilized aqueous extract of Portulaca oleracea on high-density lipoproteins composition, paraoxonase (PON1) and lecithin:cholesterol acyltransferase (LCAT) activities in streptozotocin-induced diabetic rat. Methods: Diabetes was induced intraperitonially by a single injection of streptozotocin (STZ) (60mg/kg bw). Twelve diabetic rats, weighing 263\±5g, were divided into two groups fed a casein diet supplemented or not with Portulaca oleracea extract (1g/kg bw), for 4 weeks. Results: At d28, in Portulaca oleracea treated vs untreated diabetic group, glycemia, serum total cholesterol (TC), triacylglycerols (TG) and phospholipids (PL) concentrations were decreased significantly (p\<0.05). The hypolipidemic effect induced by Portulaca oleracea extract was due to the reduction of total cholesterol (TC) in LDL-HDL1 (-51\%) and C-HDL3 (-21\%). Portulaca oleracea treatment improved PON1 and LCAT activities by 48\%. HDL3-UC (acyl group acceptor) and -PL (enzyme substrate) were diminished respectively by 47\% and 82\%, whereas HDL2-CE concentrations (product of LCAT reaction) were increased by 44\%. Moreover, HDL-C levels were found to be positively correlated with PON1 activity (r=0.96, p\<0.05). Serum, LDL-HDL1, HDL2 and HDL3 TBARS levels were respectively, 2.9-, 2.6-, 2.4- and 2.8-fold lower in Portulaca oleracea treated than untreated diabetic groups. Conclusion: These findings reflect the potential antihyperglycemic and hypolipidemic of Portulaca oleracea extract, in STZ-induced diabetic rat. Moreover, Portulaca oleracea extract restores PON1 and ameliorates the reverse cholesterol transport (RCT) by enhancing LCAT activity, therefore could prevent many diabetic complications by reducing dyslipidemia and oxidative damage.

The present investigation was carried out to evaluate the protective role of Helicteres isora plant extract on glycoprotein metabolism in streptozotocin (STZ) induced type 2 diabetic rats. Helicteres isora plant extract was administered orally (200 mg/kg body weight) for 40 days to normal and diabetic rats. The effects of Helicteres isora plant extract on plasma and tissue glycoproteins (hexose, hexosamine, sialic acid and fucose) were determined. The levels of plasma glycoproteins containing hexose, hexosamine, sialic acid and fucose were significantly increased in diabetic rats when compared with normal control rats. There was a significant decrease in the level of sialic acid and elevated levels of hexose, hexosamine and fucose in the liver and kidney of STZ induced diabetic rats. On oral administration of Helicteres isora plant extract to diabetic rats showed decreased levels of plasma glycoproteins. The level of tissue sialic acid was increased whereas the levels of tissue hexose, hexosamine and fucose were reversed to near normal. The present study indicates that the Helicteres isora plant extract possesses a significant protective effect on glycoprotein metabolism in addition to its anti-diabetic effect.
