A novel analgesic pyrazine derivative from the leaves of Croton tiglium L.
A novel analgesic pyrazine derivative, named crotonine, was isolated from the leaves of Croton tiglium L. The structure was elucidated as 2-(furan-2-yl)-5-(2,3,4-trihydroxy-butyl)-1,4-diazine by spectroscopic analysis. Crotonine inhibited remarkably the acetic acid-induced writhing in mice.
