Passiflora alata and Passiflora edulis spray-dried aqueous extracts inhibit inflammation in mouse model of pleurisy.

Abstract

The aqueous leaves extracts of Passiflora alata (100-300 mg/kg, i.p.) and Passiflora edulis (100-1000 mg/kg, i.p.) possess a significant antiinflammatory activity on carrageenan-induced pleurisy in mice. Treatment with the extracts inhibited leukocyte migration and reduced the formation of exudate. Moreover, a significant inhibition of myeloperoxidase and adenosine-deaminase activities was observed at the doses tested (100 or 250 mg/kg, i.p.). At the same doses, a significant decrease of serum C-reactive protein was observed.
