the selected parts of four medicinal plants, achillea millefolium, hibiscus rosasinensis, linum usitatissimum and pluchea lanceolata were extracted in absolute methanol to determine their analgesic activity. analgesic activity was assessed on intact mice by tail flick latency via the tail immersion method. the analgesic activities of these plant extracts were compared with acetylsalicylic acid ...

a series of 2-methylthio-1,4-dihydropyrimidine derivatives (ii) were synthesized in good yields by alkylation of 1,2,3,4-tetrahydropyrimidines (i) with methyl iodide in the presence of pyridine. their structures were confirmed by elemental analysis, ir and 1h nmr spectra. the compounds were tested for analgesic activity by acetic acid induced writhing method. compounds iih, iie, iik and iil sho...

The selected parts of four medicinal plants, Achillea millefolium, Hibiscus rosasinensis, Linum usitatissimum and Pluchea lanceolata were extracted in absolute methanol to determine their analgesic activity. Analgesic activity was assessed on intact mice by tail flick latency via the tail immersion method. The analgesic activities of these plant extracts were compared with acetylsalicylic a...

the ethanolic extract of wedelia chinensis (eewc) belonging to the family of asteraceae was evaluated by hot plate and acetic acid induced writhing methods to assess its analgesic activity. the extract was also evaluated for its by using on carrageenan, mediators such as histamine and serotonin induced paw oedema, and cotton pellet induced granuloma tests for its effect on acute and chronic pha...

derivatives of pyridine-4-one are iron chelators with various biological activities including antifungal, anti-malarial, antiviral, anti-inflammatory and analgesic activities. this study was aimed to evaluate the analgesic effect of four new derivatives of 3-hydroxy pyridine-4-one in animal models. acetic acid-induced writhing and formalin tests were used to assess the analgesic activity in mal...

Present study reports analgesic activity of petroleum ether, chloroform, ethyl acetate and methanolic extracts of leaves and seeds of Trigonella foenum-graecum Linn. (Fabaceae) using hot plate method for evaluation of central analgesic activity and acetic acid induced writhing test for evaluation of peripheral analgesic activity in mice.   All the extracts of Trigonella foenum-graecum ...

there is the need for new drugs with better action and lesser side effects. a lot of research is being undertaken to find out new plant drugs, their extraction and pharmacological evaluation. one of such plant is curcuma aromatica whichbelongs to the genus curcuma and reported to have high ethno-botanical values in traditional medicine. the present study evaluates comparative pharmacological ac...
