objective: in the present study, the effects of aqueous saffron extract (crocus sativus l.) on the acquisition and reinstatement of morphine-induced conditioned place preference (cpp) in mice were investigated. materials and methods: subcutaneous administration of morphine (40 mg/kg for four days) produced place preference. intraperitoneal administration of aqueous extract (40 and 80 mg/kg for ...

Petroleum ether (60 degrees-80 degrees C), chloroform, acetone, ethanol, aqueous and crude hot water extracts of the whole plant of C. dactylon and the two fractions of aqueous extract were tested for antihyperglycaemic activity in glucose overloaded hyperglycemic rats and in alloxan induced diabetic model at two-dose levels, 200 and 400 mg/kg (po) respectively. The aqueous extract of C. dactyl...

BACKGROUND The phenolic contents and antioxidant activities of fruits could be underestimated if the bound phenolic compounds are not considered. In the present study, the extraction efficiencies of various solvents were investigated in terms of the total content of the free and bound phenolic compounds, as well as the phenolic profiles and antioxidant activities of the extracts. METHODS Five...

objective(s) this study planned to assess antidepressant like activity of aqueous extract from leaves of citrus maxima merr. (rutaceae). materials and methods boiling was used for aqueous extraction. acute toxicity study was performed in mice. antidepressant activity was studied using locomotor activity test, modified forced swimming test (fst) and tail suspension test (tst). three doses 100, 2...

Anticonvulsant activity of aqueous (AQHE) and ethanolic (ETHE) extract of Hybanthus enneaspermus was studied using maximal electric shock (MES) and strychnine induced convulsions models. AQHE at the doses of 200 mg/kg and 400 mg/kg orally showed significant protection in both models. The activity was equipotent to phenobarbitone sodium (30 mg/kg; i.p.). The AQHE showed no neurotoxicity. Ethanol...

The aqueous extract of Abutilon indicum was tested for hepatoprotective activity against carbon tetrachloride- and paracetamol-induced hepatotoxicities in rats. A. indicum exhibited significant hepatoprotective activity by reducing carbon tetrachloride- and paracetamol-induced change in bio-chemical parameters that was evident by enzymatic examination. The plant extract may interfere with free-...

Forty days of orally feeding the aqueous E. ribes extract (100 and 200 mg/kg) to streptozotocin (40 mg/kg, iv, single dose) induced diabetic rats produced significant decrease in heart rate, systolic blood pressure, blood glucose, blood glycosylated hemoglobin, serum lactate dehydrogenase, creatine kinase and increase in blood glutathione levels as compared to pathogenic diabetic rats. Further,...

In the present study, ethyl acetate, butanol and aqueous fractions derived from total methanol extract of Butea monosperma flowers were evaluated for radical scavenging activities using different in vitro models like reducing power assay, scavenging of 2,2 diphenyl-1-picrylhydrazyl (DPPH) radical, nitric oxide radical, superoxide anion radical, hydroxyl radical and inhibition of erythrocyte hem...

A vast majority of the studies addressing the free radicals including hydroxyl radical is a damage compound of biochemical molecules such as DNA, proteins and lipids. When free radicals specially hydroxyl radical are not adequately removed from the body, it may damage biological macromolecules, leading to a variety of disease occurs. Therefore, the body should be protected by an enzymatic or no...
