Bishordeninyl terpene alkaloids from Zanthoxylum integrifoliolum

Examination of the leaves of Zanthoxylum integrifoliolum led to the isolati on of a new bishordeninyl alkaloid, integramine, along with alfileramine, a lpha-allocryptopine, pseudoprotopine and (+)-sesamin from the tertiary non- phenolic base fraction. The structures of these compounds were elucidated b y spectral evidence.
