Abstract

Dahlia pinnata Cav. (Asteraceae), commonly known as Dalia in Bengali, is a bushy, herbaceous ornamental plant indigenous to Mexico and widely cultivated in different regions of India. The present study assessed three different successive solvent extracts from D. pinnata leaf for their analgesic potential by acetic acid induced writhing assay in Swiss albino mice. All the test extracts exhibited significant analgesic activity. The methanol extract was found to be the most potent followed by the chloroform and petroleum ether extracts respectively. The present preliminary study demonstrated marked analgesic activity of D. pinnata leaf in Swiss albino mice.
