Parkinsonia aculeata aqueous extract fraction: Biochemical studies in alloxan-induced diabetic rats

Aims: The current investigation aimed to assess the antioxidant, antidiabetic and antilipidemic effects of the aqueous extract of aerial part of Cotula cinerea (C. cinerea). Background: Cotula cinerea (Del). which belongs to the Asteraceae family is commonly used traditionally for the treatment of diabetes. Objective: The objective of the study was to study the effect of the aqueous C. cinerea extract on glucose and lipid metabolism in normal and streptozotocin-induced diabetic rats using a single and repeated oral administration. Methods: A preliminary phytochemical screening and the quantification of phenolic and flavonoid contents as well as the antioxidant activity using three methods (DPPH, FRAP and ABTS) were carried out. The effect of a single and repeated (15 days of treatment) oral administration of the aqueous extract of aerial part of Cotula cinerea (AEAPCC) at a dose of 20 mg/kg on glucose and lipid profile was examined in normal and streptozotocin-induced diabetic rats. Additionally, histopathological examination of the pancreas and liver was carried out according to the Hematoxylin-Eosin method. Results: AEAPCC (20 mg/kg) showed a significant blood glucose-lowering activity in both normal and diabetic rats after a single and repeated oral administration during 15 days. The aqueous extract was also able to decrease the plasma triglycerides levels in both normal and diabetic rats after 15 days of oral treatment at a dose of 20 mg/Kg while no effect was observed on plasma cholesterol levels. In addition, the results show that AEAPCC exhibits an in vitro antioxidant activity using different tests. Histopathological analysis of the pancreas and liver of AEAPCC-treated diabetic rats has revealed that AEAPCC had a beneficial effect on the architecture of these organs while no improvement of glucose tolerance was noticed using the glucose tolerance test. Furthermore, the results showed that the extract is rich in several phytochemical compounds and exhibited an important antioxidant activity. The phytochemical screening revealed that AEAPCC contains polyphenolic compounds, flavonoids, tannins, alkaloids, saponins, quinones, sterols, terpenoids, anthroquinones and reducing sugars. Whereas, it is free from glycosides. Conclusion: In conclusion, this study demonstrates that Cotula cinerea possesses a beneficial effect on diabetes. Further investigations are required to study the mechanism of action of the antidiabetic effect of this plant.

Objective: The aim of this work was to evaluate the antihyperglycemic activity of aerial parts aqueous extract (A.P.A.E) of Mentha pulegium (M. pulegium) on blood glucose levels in normal and streptozotocin(STZ)-induced diabetic rat. The glucose tolerance was evaluated in normal rats. Moreover, the histological sections and morphometric analysis at the liver and pancreas have been carried out in this investigation both in normal and STZ-diabetic rats. Methods: The effect of A.P.A.E of M. pulegium (20 mg/kg) on blood glucose levels was investigated in normal and diabetic rats (n=6). Histopathological changes in liver and pancreas were examined under phase contrast microscope and a preliminary screening for various bioactive constituents was realized according to standard methods. Key Findings: Both single and repeated oral administration of A.P.A.E (20 mg/kg) caused a significant reduction in blood glucose levels in STZ-diabetic rats (p<0.0001). The morphometric analysis and histological sections realized in pancreas and liver have showed the beneficial effect of the A.P.A.E in cellular population. According to oral glucose tolerance test (OGTT), the aqueous extract has revealed an improvement of glucose tolerance in normal rat. Furthermore, the preliminary phytochemical screening of A.P.A.E of M. pulegium has demonstrated the presence of various metabolite compounds including polyphenols, flavonoids, terpenoids tannins, cyanidins, sesquiterpenes, and glycosides. Conclusion: We conclude that the A.P.A.E of M. pulegium (20 mg/kg) exhibits a potent antihyperglycemic activity in STZ diabetic rats.

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.
