Background: The ethanomedicinal importance of Moringa concanensis Nimmo plant is reflected in Ayurvedic and traditional system of medicine. It brings out its importance as diverse plant in Ayurvedic preparation and diabetes management. Aims of study: The research was centred to bring out the Hyperglycemiccapabilities of Moringa concanensis Nimmo leaves Ethanolic extract (PE) on Alloxan monohydrate (AXM) induceddiabetic rat model. Materials and Methods: Wistar rats were made diabetic by AXM and treated with PE (200 mg/kg body weight) and glibenclamide as a standard drug. All Essential parameters like Fasting blood glucose (FBS), Post prandial blood glucose (PPBS), AST, ALT, ALP, ACP, LDH and oxidative stress markers were measured. Also to see β-cells structures histology of pancreas was also done. Results: The non toxicity of PE dose was confirmed by acute toxicity study and also this study models helped to know about the anti-hyperglycemic effects of PE by decreasing FBS and PPBS levels in the diabetic rats. It also enhances oxidative stress by decreasing MDA levels and elevating the GSH and SOD. The histopathological analysis helped us to know about structure decay of β-cells of pancreas tissue of diabetic rats. PEpotential was confirmed by serum enzymes AST, ALT, ALP, ACP and LDH as it showed significant decrease in diabetic rats. Conclusion: It was confirmed from the data that PE is efficient in governance of diabetes and its control, so there is a need to work at molecular level to bring out all its potential for the benefit of the society.

Objective: The antihyperglycemic and antioxidative effects of L. microphyllum were evaluated by using in vivo methods in normal and alloxan induced diabetic rats.Methods: Diabetes was induced in Sprague Dawley rats by injecting alloxan through intravenous (i. v) at a dose of 100 mg/kg of body weight. Aqueous extract of L. microphyllum at different doses (400, 200 and 100 mg/kg of body weight) was administered orally (orogastric intubation) for 14 d. Blood glucose and oxidative stress markers were measured. Hematoxylin and eosin staining method were used to examine the pancreatic tissues.Results: At the 14 d interval, fasting blood glucose showed a reduction in serum glucose levels in animals pretreated with L. microphyllum compared with alloxan alone treated group. Oxidative stress was noticed in rat’s pancreatic tissue as evidenced by a significant decrease in glutathione level, glutathione reductase, glutathione-S-transferase, and catalase activities. Malondialdehyde showed a significant increase compared to the normal saline-treated control group. Serum biochemistry and oxidative stress markers were consistent with the pancreatic histopathological studies. Treatment of diabetic rats with L. microphyllum at a dose level of 100, 200 and 400 mg/kg body weight leaves extract for 14 d significantly prevented these alterations and attenuated alloxan-induced oxidative stress (P<0.05).Conclusion: The results of the present study indicated that the antihyperglycemic potential of L. microphyllum might be ascribable to its antioxidant and free radical scavenging properties. Thus, it is concluded that L. microphyllum may be helpful in the prevention of diabetic complications associated with oxidative stress.

The aim of the present study was to evaluate the protective effect of methanol garlic extract on the enzymes related with polyol pathway, advanced glycation end products, markers of oxidative stress and antioxidant status in brain of streptozotocin induced diabetic rats. Antioxidant capability of methanol extract of garlic was evaluated by 2,2-diphenyl-2-picrylhydrazyl hydrate radical and FOX (ferrous ion oxidation-xylenol orange) H2O2 scavenging test. Diabetes was induced by single i.p injection of STZ (32mg/kg per body Wt.,). Blood glucose levels and body wt, were measured on every 7th day over a period of 30 days. The diabetic rats treated with garlic extract at two doses 250mg/kg and 500mg/kg body wt., by oral administration. Diabetic rats showed significant increase in food and water intake, decrease in blood glucose levels, body weights, but could not show any recovery by garlic treatment. Garlic treatment significantly decreased aldose reductase (AR); sorbitol dehydrogenase (SD) and glutathione S-transferase (GST) enzyme activities. A decrease of malndialdehyde (MDA), Protein carbonyls (PC), Pentosidine advance oxidation protein products (AOPP), Advanced glycation end products (AGEs) was also observed. Additionally garlic administration produced a restoration of brain superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and reduced glutathione (GSH) in diabetic rats. Garlic treatment also reduced the free radical formation and progression of hyperglycemia induced diabetic complications by decreasing influx of glucose into the polyol pathway and increased activity of antioxidant enzymes. The current study reveals exerts, efficiently, an attenuating effect of methanol garlic extract exterted antihyperlgycemic, antioxidant and anti-glycating effects in a dose dependent manner in diabetic rats.

Abstract Background Natural medicinal plants have been the focus of current research for developing neuroprotective agents to be used in the diabetes-linked cognitive dysfunction. Trigonella foenum-graecum seeds (known as fenugreek, methi in Hindi), is a well-known traditional medicinal herb and possesses anti-diabetic, anti-oxidant, and anti-inflammatory properties. Purpose This study was undertaken to explore the ameliorative effects of T. foenum-graecum seed extract on diabetes-induced cognitive dysfunction. Methods Experimental diabetes was induced by administering a single dose of streptozotocin (60 mg/kg) through intraperitoneal dose. Cognitive function was assessed using a T-maze and the Morris water maze. Lipid peroxidation levels and oxidative stress in the hippocampus was measured. Quantification of hippocampal CA1 and CA3 regions was done using cresyl violet stain. Results Diabetic rats demonstrated learning and memory impairment, which was evident from poor performance in behavioral tasks, i.e. T-maze and Morris water maze tasks. Learning and memory impairment in diabetic animals is associated with increased blood glucose levels, increased oxidative stress in the hippocampus and decreased number of neurons in the CA1 and CA3 regions of the hippocampus. The diabetic rats administered with T. foenum-graecum showed improved performance in behavioral tasks, and these changes were associated with decreased blood glucose levels, decreased oxidative stress in the hippocampus, and decreased neuronal loss from the CA1 and CA3 regions of the hippocampus. Conclusion In conclusion, administration of T. foenum-graecum seed extract ameliorates diabetes-linked cognitive dysfunction in rats by decreasing blood glucose levels, reducing lipid peroxidation and oxidative stress in the hippocampus, and preventing neuronal loss from the hippocampus.
