The essential oil of long-pepper (Piper hispidinervum C. DC) is rich in safrole, then susceptible to isomerization reaction to obtain cis, trans-isosafrole. In this paper it is presented the eletroxidation of cis, trans-isosafrole from direct isomerization of essential oil of long-pepper, with 99,7% of convertion to isosafrole glicol, that it is react by oxidation to convert 99% into piperonal with 84,9% purity.
