Abstract
In present study evaluate the analgesic and anti-inflammatory activity of the compound obtained from the petroleum ether (40 - 60<TEX>$^{\circ}C$</TEX>) extract of the fruits from Dregea volubilis in Swiss albino mice and in Wister albino rats respectively. Dried and crushed fruits of Dregea volubilis were extracted by petroleum ether (40 - 60<TEX>$^{\circ}C$</TEX>), the proper solvent system was developed by TLC and subjected to column chromatography for obtaining the pure compound/s. IR, MASS, NMR (PMR, C13 NMR and DEPT) spectroscopic analysis were done to elucidate the structure of the compound/s. The petroleum ether (40 - 60<TEX>$^{\circ}C$</TEX>) extract of the fruits of Dregea volubilis led to isolation of a pentacyclic triterpenoid designated as taraxerone and characterized as D- friedoolean- 14- en, 3 one. Taraxerone had been screened for analgesic activity in Swiss albino mice and anti-inflammatory activity in Wister albino rats at the dose of 5 mg/kg body weight orally and exhibit significant analgesic and anti-inflammatory properties.
