The stem bark of Zanthoxylum decaryi yields this alkaloid which forms orange needles when purified by recrystallization from MeOH-CHC13. It gives a complex ultraviolet spectrum in EtOH having absorption maxima at 249, 257, 277, 326 and 382 nm with shoulders at 285 and 335 nm. The structure has been determined from chemical degradation and spectroscopic examination.

Decarine can be used to crudely extract constituents of bark of Fagara tessmannii toward multi-factorial drug resistant cancer cells. It can also be used to create anti-mildew preservative paper with good barrier properties and solar water heater anti-freezing liquid,

ChEBI: A natural product found particularly in Zanthoxylum caudatum and Zanthoxylum viride.
