Many plants provide a rich source of bioactive chemicals, which are free from undesirable side effects and possess powerful pharmacological actions. The present study was carried out to find the antidiabetic effect of   Katakakhadiradi kashayam (KKK) by improving the insulin expression and regulating properly the glucose metabolising enzymes. The diabetes was induced in combination with streptozotocin and nicotinamide injection to Wistar rats. Diabetic rats were treated with   Katakakhadiradi kashayam orally at doses of 100, 200 and 300 mg/kg/bw for 28 days, and the obtained results of parameters were compared with glibenclamide. The antidiabetic effect of Kashayam was measured by the expression of insulin by immunohistochemistry and restoring the normal clinical values of glucose metabolizing enzymes. The present study specified that hyperglycemia leads to pathological conditions in pancreatic tissue with decreased expression of insulin in β-cells whereas the   Katakakhadiradi kashayam normalised the production of insulin. The study found that the antihyperglycemic activity of   Katakakhadiradi kashayam L. is mainly due to their ability to restore the function of pancreatic tissues by causing an increase in insulin output and maintaining the glucose metabolising enzymes.

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.

Context. Nigella sativa seeds are usually used as traditional medicine for a wide range of therapeutic purposes. Objective. To investigate the subacute toxicity of NS aqueous extract and select its lowest dose to study its antidiabetic effect. Methods. 5 AqE.NS doses (2, 6.4, 21, 33, and 60 g/Kg) were daily administered to mice by gavage. Biochemical parameters measurements and histological study of the liver and the kidney were performed after 6 weeks of supplementation. Thereafter, and after inducing diabetes by alloxan, rats were treated by 2 g/Kg of AqE.NS during 8 weeks. Metabolic parameters were measured on sera. A horizontal electrophoresis of plasmatic lipoprotein was conducted. Glycogen, total lipids, and triglycerides were measured in the liver. TBARS were evaluated on adipose tissue, liver, and pancreas. Results. AqE.NS showed no variation in urea and albumin at the 5 doses, but hepatotoxicity from 21 g/Kg was confirmed by histopathological observations of the liver. In diabetic rats, AqE.NS significantly decreased glycemia, TG, T-cholesterol, LDL-c, and TBARS and showed a restored insulinemia and a significant increase in HDL-c. Results on the liver indicated a decrease in lipids and a possible glycogenogenesis. Conclusion. AqE.NS showed its safety at low doses and its evident antihyperglycemic, antihyperlipidemic, and antioxidant effect.

Aims: The aim of the study was to evaluate the antihyperglycemic effect of Chenopodium quinoa. Background: Chenopodium quinoa is a pseudocereal plant with several medicinal properties. Objective: The goal of this investigation was to determine the antihyperglycemic activity of Chenopodium quinoa in both normal and streptozotocin(STZ)-induced diabetic rats. Methods: In this study, the effect of the aqueous extract of Chenopodium quinoa seeds (AECQS) (60 mg/kg) on blood glucose levels was evaluated in both normal and diabetic rats after a single (6 hours) and repeated oral administration (7 days of treatment). The effect of this herb on glucose tolerance and lipid profile was also studied. Additionally, histopathological examination of liver was carried out using the Hematoxylin-Eosin method. Furthermore, the in vitro antioxidant activity as well as a preliminary phytochemical screening and quantification of some secondary metabolites (phenolic compounds, flavonoids and tannins) were performed according to standard methods. Results: AECQS produced a significant lowering effect on plasma glucose levels in STZ-induced diabetic rats. In addition, this extract exhibited a remarkable amelioration on hepatic histopathology in diabetic rats. In addition, the extract exerted a remarkable antioxidant activity which could be due to the presence of some compounds found in this herb. Conclusion: In conclusion, this study demonstrates that the aqueous extract of Chenopodium quinoa seeds has a favorable effect in controlling diabetes mellitus.
