    Valeriana pinnatifida is a native plant of the Valerianaceae family, endemic to Peru, which grows on rocky slopes in the Andes. Traditionally, it has been used as a sedative, hypnotic, and tranquilizer. This study was initiated to analyze the metabolites present in the plant, determine its acute toxicity, and evaluate its anticonvulsant effect. The research was quasi-experimental. For the phytochemical study, a hydroalcoholic extract was obtained from the root of Valeriana pinnatifida R. & P., "valeriana," via maceration. Acute toxicity was determined at a limit dose of 2000 mg/kg using the OECD 423 protocol. The anticonvulsant effect was evaluated using an experimental model of pentylenetetrazol (PTZ)-induced seizures in mice. Five groups of six albino mice of the C53/CNPB strain were used: group 1 (saline control), group 2 (PTZ 80mg/kg), group 3 (diazepam 5mg/kg + PTZ), group 4 (EHVP 300mg/kg + PTZ), and group 5 (EHVP 400mg/kg + PTZ). The treatments were administered orally 30 minutes before the induction of seizures with PTZ. The results identified the secondary metabolites alkaloids and terpenes. The toxicity study showed a significant variation in the weight of the mice. The 300 mg/kg dose demonstrated a statistically significant anticonvulsant activity compared to the control group in terms of seizure severity and mortality. It is concluded that the hydroalcoholic root extract of Valeriana pinnatifida R. & P., "valeriana," at a concentration of 300 mg/kg, exhibits an anticonvulsant effect.
