抄録

Anti-inflammatory and analgesic principles were isolated from the methanol extract of the whole herb of Pyrola rotundifolia L., based on bioassays of the inhibitory activities on carrageenaninduced hind paw edema in rats and on acetic acid-induced writhing in mice. The principles were identified as ursolic acid and chimaphilin.
