The Methanolic extract of leaves (LE) and Methanolic extract of flowers (FE) of Nerium indicum (Arali) was analysed for Antioxidant activity (AOA) in terms of DPPH free radicals, Total Phenolic Content (TPC) was measured in terms of Gallic acid equivalent and Flavonoid content was analysed in terms of Quercetin equivalent. The antioxidant activities of (LE & FE) were found to be 72.8% and 67 %. TPC of study extracts (LE & FE) were found to be 227 mg/100g and 449 mg/100g. The Total Flavonoid content of (LE & FE) were found to be 125 mg/100g and 199 mg/100g respectively. Superoxide anion radical scavenging activity of flowers was 66 % compared to leaves 25 %. Similarly Lipid Peroxidation showed higher activity in flowers than leaves. Enzymatic antioxidant activity such as Superoxide Dismutase, Glutathione peroxidase and Catalase of Nerium indicum flowers were around 10% to 30% higher than that of leaves. The results clearly indicate that the methanol extracts of Nerium indicum flowers have more potent antioxidant activity than...

The present study was designed to determine the antidiabetic activity of the methanol: ethyl acetate (1:9) extract of flower buds of Peltophorum pterocarpum on alloxen and glucose indueced diabetic mouse model. The extract was given intraperitonially at a dose of 200 mg/kg body weight and the hypoglycemic effects compared with metformin, a standard drug. The extract reduced blood glucose level in alloxan-induced diabetic mice by 60.40%, and 65.48% reduced by metformin at 12 hours in 24 hours treatment period. Preliminary phytochemical screening of the extract revealed the presence of different types of compounds including flavonoids and steroids. Our results suggest that Peltophorum pterocarpum has potential antidiabetic activity and may provide new molecules for the treatment of...

Cyclocondensation of α-bromo ketones with thiourea afforded 4-substituted 1, 3-thiazole-2-amines. These compounds on further treatment with α-bromo ketones afforded 3, 6-disubstituted imidazo[2, 1-b][1, 3]thiazole (1a-1j). All the synthesized compounds were confirmed for their structure by FTIR, 1H NMR and GSMS spectra and tested in vitro for their anti-microbial activity by cup plate method against Gram-positive bacterial strains (Bacillus subtillis, Staphylococcus aureus) Gram-negative bacterial strains (Pseudomonas aerugenosa, Kleibsella pneumonia) and fungal strains (Aspergillus niger, Candida albicans). The analogues 1b, 1h and 1i showed promising antimicrobial activity against gram-negative Kleibsella pneumonia; where as analogues 1b, 1e, 1g and 1h showed promising antifungal activity against Candida...

The objective of present study is to evaluate the anti ulcer activity of ethanol extract of leaves of Heliotropium indicum. The ethanol extract of H. indicum was investigated for its anti ulcer activity against Aspirin plus pylorus ligation induced gastric ulcer in rats, HCl- Ethanol induced ulcer in mice and water immersion stress induced ulcer in rats. The antiulcer activity was assessed by determining and comparing gastric volume, free acidity and ulcer inhibition in aspirin plus pylorus ligation induced gastric ulcer model. The number of lesions in HCI-Ethanol induced peptic ulcer model and mean score value of ulcer inhibition in water immersion stress induced ulcer model. A significant antiulcer activity of plant extract was observed in all the models. Pylorus ligation model showed significant reduction in gastric volume, free acidity and ulcer index as compared to control. Also extract showed significant ulcer inhibition in HCl- Ethanol induced ulcer and ulcer protection index in stress induced ulcer. This present study indicates that Heliotropium indicum leaves extract have potential anti ulcer...

In Traditional Ayurvedic system of treatment Tragia involucrata Linn. is intended to use for diabetic patients has been screened for antioxidant activity. For antioxidant studies, aqueous ethanolic extract of Tragia involucrata (AEETI) was administered orally for 28 days at a dose of 250 and 500 mg/kg body weight to Streptozotocin- Nicotinamide induced Wistar rats. All the animals were sacrificed on the 29th day and the levels of LPO, SOD, CAT, GPx and GSH in kidney and liver of control and experimental rats were studied. The AEETI exhibited significant antioxidant activity showing increased levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), reduced glutathione (GSH) and decreased level of lipid peroxidation. These results showed that treatment with AEETI lowers Streptozotocin induced LPO and alters SOD, CAT, GPx and GSH enzymes to reduce oxidative...
