Abstract

Pterocarpus marsupium Roxb. (Leguminosae), commonly known as Indian kino or Malabar kino in English, is a large deciduous tree widely distributed in different regions of India. It is traditionally used In India for several medicinal purposes. The present study assessed three different successive solvent extracts from P. marsupium 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 ethyl acetate and petroleum ether extracts respectively. The present preliminary study demonstrated marked analgesic activity of P. marsupium leaf in Swiss albino mice.
