Pharmacologically active components of a Peruvian medicinal plant, huanarpo (Jatropha cilliata).

From Jatropha cilliata M. Arg., a Peruvian medicinal plant, isoorientin and orientin were isolated as 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.
