Zanthoxylum hawaiiense
Zanthoxylum hawaiiense, commonly known Aʻ e or Hawaiʻ i pricklyash, is a species of flowering plant in the citrus family, Rutaceae, that is endemic to Hawaii.

 It is threatened by habitat loss.
Chelerythrine
Chelerythrine is a benzophenanthridine alkaloid present in the plant "Chelidonium majus" (greater celandine).
 It is a potent, selective, and cell-permeable protein kinase C inhibitor "in vitro".
 And an efficacious antagonist of G-protein-coupled CB1 receptors.
 It is also found in the plants "Zanthoxylum clava-herculis" and "Zanthoxylum rhoifolium", exhibiting antibacterial activity against "Staphylococcus aureus" and other human pathogens. Nitidine
Nitidine is a benzophenanthridine alkaloid found in species of the genus "Zanthoxylum ", notably in "Zanthoxylum nitidum".
 This compound has an anti-malarial activity. Zanthoxylum psammophilum
Zanthoxylum psammophilum (synonym Fagara psammophila Aké Assi) is a species of shrub or small tree in the Rutaceae family.
 It is a large liana endemic to Côte d'Ivoire, although in 2005 it was found in Liberia as well.
 "Zanthoxylum psammophilum", a new combination created in 1975 to subsume the genus "Fagara" into the genus "Zanthoxylum" based on morphology and secondary metabolites, is the preferred name according to the Conservatoire et Jardin botaniques de la Ville de Genève which has a section that specializes in the conservation and biodiversity of flowering plants of Côte d'Ivoire.
 However, the International Plant Names Index lists "Fagara" as the genus, and "Zanthoxylum" as the synonym.
 The type specimen for the plant was collected in the ecotone between the lowland Eastern Guinean forests (tropical rainforest) and the inland Guinean forest-savanna mosaic in the Lagunes District. List of islands in Isle Royale National Park
