Preliminary results on the protective effect of (-)-edunol, a pterocarpan from Brongniartia podalyrioides (Leguminosae), against Bothrops atrox venom in mice.
(-)-Edunol a prenylated pterocarpan was isolated from the roots of two Mexican 'snakeweeds', Brongniartia podalyrioides and B. intermedia (Leguminosae). Edunol (3.1 mg/kg, i.p.) reduced the expectedExpand
