Diabetes mellitus (DM) is a now a major global health problem and its incidence is increasing day by day in whole world. There are various medicinal plants in India those possess antidiabetic property which are traditionally used in management of diabetes. Tectona grandis Linn. (TG) plant belonging to family Verbenaceae is medicinally reported and claims to cure various diseases in Indian traditional system of medicine (Ayurveda) and also in folklore. The purpose of this present study is to examine the hypoglycemic potential of methanol fractions (50, 100 and 200mg/kg body weight) of Tectona grandis bark (MFTG) from defatted hydro-alcoholic extract in normoglycemic, streptozotocin induced (45mg.kg‒1) diabetic and glucose loaded hyperglycemic rats by single and multiple oral administration in comparison to standard drug Glibenclamide (2.5 mg/kg body weight). Initially acute oral toxicity study of MFTG was carried out in rats to estimate the dose for animal study. The study report showed that the MFTG (200mg/kg) significantly (p<0.05 to p<0.01) reduces blood glucose level both in normoglycemic and diabetic rats induced by Streptozotocin and oral glucose loaded methods till the end of 8 hour and 3hour respectively during the single dose study and from the 15th day to 30th day in multi dose study. Hence the present study reveals that MFTG possess significant hypoglycemic activity which inspires the traditional use of the plant for the treatment of diabetes mellitus.

Diabetes mellitus is the most common chronic disease in the world, and a wide range of drugs, including Chinese herbs, have been evaluated for the treatment of associated metabolic disorders. This study investigated the potential hypoglycemic and renoprotective effects of an extract from the solid-state fermented mycelium ofCordyceps sinensis(CS). We employed the KK/HIJ diabetic mouse model, in which the mice were provided with a high-fat diet for 8 weeks to induce hyperglycemia, followed by the administration of CS or rosiglitazone for 4 consecutive weeks. Several parameters were evaluated, including changes in body weight, plasma lipid profiles, oral glucose tolerance tests, insulin tolerance tests, and plasma insulin concentrations. Our results show that the CS extract significantly elevated HDL/LDL ratios at 4 weeks and decreased body weight gain at 8 weeks. Interestingly, CS treatment did not lead to obvious improvements in hyperglycemia or resistance to insulin, while in vitro MTT assays indicated that CS protects pancreatic beta cells against the toxic effects of STZ. CS also enhanced renal NKA activity and reduced the accumulation of mesangial matrix and collagen deposition. In conclusion, CS extract can potentially preserveβ-cell function and offer renoprotection, which may afford a promising therapy for DM.

Punica granatum (Family: Punicaceae) is a widely consumed fruit in Bangladesh locally known as Anar or Bedana. Traditionally the plant is used to treat diarrhoea, dysentery, hemorrhage, tuberculosis and chronic periodontitis. The present study was undertaken in order to justify and authenticate the traditional use of rind of P. granatum fruit in diarrhoea. Methanolic extract of the rind of the fruit was tested in castor oil- and magnesium sulfate-induced diarrhoea in mice at the doses of 200 and 400 mg/kg body weight. The results of the present study revealed significant antidiarrhoeal activity (p<0.001) in both animal models. The extract inhibited 31.25% defaecation at the dose of 200 mg/kg and 53.75% at the dose of 400 mg/kg in castor oil-induced diarrhoea while standard drug loperamide inhibited 71.25% defaecation. In magnesium sulfate-induced diarrhoea the inhibition of defaecation was 45.71 and 57.14% at the doses of 200 and 400 mg/kg respectively while loperamide inhibited 64.29% defaecation. The antidiarrhoeal effect of the extract was concentration dependent in both castor oil-induced diarrhoea and magnesium sulfate-induced diarrhoea. Phytochemical screening of the extract revealed the presence of flavonoids and alkaloids that may play key role in its antidiarrhoeal activity. The results of the present study validate the folkloric use of the rind of P. granatum in the treatment of diarrhoea.DOI: http://dx.doi.org/10.3329/icpj.v2i5.14437 International Current Pharmaceutical Journal, April 2013, 2(5): 101-104

Type 2 Dm

Diabetes mellitus (DM) is currently ranked among leading causes of death worldwide in which type 2 DM is reaching an epidemic proportion. Hypoglycemic medications for type 2 DM have either proven inadequate or posed adverse effects; therefore, the Chinese herbal products are under investigation as an alternative treatment. In this study, a novel combination of fruiting body and mycelia powder of herbalCordyceps militarisnumber 1 (CmNo1) was administered to evaluate their potential hypoglycemic effects in high-fat diet- (HFD-) induced type 2 DM in C57BL/6J mice. Body weight, fasting blood glucose (FBG), oral glucose tolerance test (OGTT), and blood biochemistry indexes were measured. Results indicated that CmNo1 lowered the blood glucose level by increasing insulin sensitivity, while no change in body weight was observed. Increased protein expression of IRS-1, pIRS-1, AKT, pAKT, and GLUT-4 in skeletal muscle and adipose tissue was found indicating restoration of insulin signaling. Additionally, PPAR-γexpression in adipose tissue restored the triglyceride and cholesterol levels. Finally, our results suggest that CmNo1 possesses strong hypoglycemic, anticholesterolemic, and antihypertriglyceridemic actions and is more economical alternate for DM treatment.

The purpose of this study was to evaluate the potential antidiabetic drug Triphala guggul (TG), an indigenous polyherbal Ayurvedic formulation in an alloxan-induced diabetes rat model. Diabetes mellitus was induced in rats. The rats were divided into nine groups, including the groups of normal control which received the vehicle, the standard group (Glibenclamide) and rats with induced diabetes were treated with the tablet of Triphala guggul and Triphala guggul churna in doses of 100, 200, 400 mg/kg body weight, respectively. They were administered orally for 28 days on a single dose. Blood was collected from the vein in the tail on days 7, 14, 21 and 28. Biochemical estimates were made using blood serum. Acute toxicity studies did not reveal toxicity in rats. For 28 days, Administration of Triphala guggul tablet and Triphala guggul churna formulations improved oral glucose tolerance in diabetes-induced rats and after 28 days, resulted in a significant reduction in serum glucose level compared to normal control rats. These formulations do not affect the kidney, adipose tissue, and liver. The Triphala guggul formulation has a promising antidiabetic property and is effective in the treatment of diabetes.

AbstractLotus (Nelumbo nucifera Gaertn), a kind of perennial aquatic plant, is widely cultivated and consumed by people in Asian countries. Lotus plumule flavonoids (LPF) have been recognized as a hypoglycemic agent. LPF was optimally obtained using novel ultrasonic-microwave assisted synergistic extraction (UMSE) method by response surface methodology (RSM) on the basis of the results of single-factor experiments. Furthermore, the hypoglycemic activity of LPF was investigated by measuring the body weight, fasting blood glucose (FBG) level, and oral glucose tolerance test (OGTT) and analyzing the physiological indexes in streptozotocin-diabetic mice model. The optimum extraction conditions consisted of microwave power 355 W, ultrasonic power 423 W, extraction time 15 min, solid-liquid ratio 1:40, ultrasound/interval time 1/0, and ethanol concentration 70% with the maximum LPF yield of 2.62%. LPF supplementation significantly decreased the body weight, FBG, OGTT, serum total cholesterol (TC), serum total triglycerides (TG), and insulin levels, indicating the antidiabetic activity of LPF. This research verified that the UMSE technique was highly efficient to extract LPF to the maximum extent and the flavonoids from L. plumule exhibited hypoglycemic activity, which showed broad development and application prospects.

Spondias pinnata (L.f.) Kurz. (family: Anacardiaceae) is a wild deciduous tree indigenous to southeast Asian countries. Different parts of this plant are used traditionally for the treatment and cure of various disorders and illnesses. S. pinnata leaves are used to prevent and treat diabetes in traditional Balinese medicine. However, scientific study on the antihyperglycemic effect of its leaves has not been reported yet. Therefore, this study aims to perform phytochemical screening and investigate the hypoglycemic potential of S. pinnata leaves extract. Preliminary phytochemical screening of the hydroethanolic extract was performed following the standard tests. In vivo hypoglycemic activity of the leaves extract was evaluated using normal and glucose-loaded rats. The results displayed the presence of phytochemical constituents such as saponins, phenolic compounds, flavonoids, and terpenoids. S. pinnata (500 mg/kg) and metformin (100 mg/kg) exhibited a significant ( p < 0.05 ) decrease in blood glucose level at 1, 2, and 3 h in normal rats when compared to the control group. Metformin- (100 mg/kg)- and S. pinnata- (500 mg/kg)- treated groups showed a maximum decrease in the blood glucose level at 3 h after single-dose administration in the oral glucose tolerance test (OGTT). In conclusion, S. pinnata leaves possess a significant hypoglycemic activity in the animal model and thus support its traditional use to treat diabetes. Therefore, a detailed mechanism-based study and isolation of bioactive compounds from S. pinnata leaves would be beneficial in the future for the search of new hypoglycemic agents.
