From Jatropha cilliate M. ARG., a Peruvian medicinal plant, isoorientin and orientin were isolated anxiolytic components by using the isolation guide of anti-conflict effect in mice. Several related flavonoids were also tested for this effect. Another bioassay-guided isolation using the acetic acid-induced writhing method gave a coumarin compound, fraxetin, as an analgesic principle.
