Zanthoxylum coco

Redemann, Wisegarver, and Alles (35, c.f. 36) have identified a-fagarine or fagarine I, from Zanthoxylum coco Gill.), as a-allocryptopine. This compound is also known as /3-homochelidonine. A higher-melting isomer... 

While isoquinolines are elaborated by a number of natural orders, there are only two exceptions to the statement that the protopine bases are found only in the Papaveraceae. These exceptions are the occurrence of a-al-locryptopine ( S-homochelidonine) in Zanthoxylum brachyacanthum F. Miill. and in Z. coco Gill. Fagara coco (Gill.) Engl.), plants belonging to the Rutaceae, and of protopine in Nandina domestica Thunb. (Berberidaceae). 

Allocryptopine has been found in plants outside of the Papaveraceae first by Jowett and Pyman (78) in Zanthoxylum brachyacanthum and then in Z. coco (79), from the latter of which it was first recorded under the name of a-fagarine (80).
