<jats:title>Abstract</jats:title><jats:p>Examination of the leaves of <jats:italic>Zanthoxylum integrifoliolum</jats:italic> led to the isolation of a new bishordeninyl alkaloid, integramine, along with alfileramine, α‐allocryptopine, pseudoprotopine and (+)‐sesamin from the tertiary non‐phenolic base fraction. The structures of these compounds were elucidated by spectral evidence.
