Harmol

Harmol is a ß-carboline alkaloid compound present in fruits, herbs, spices, and sea-buckthorn berries.1 It was recently isolated from several species of mushrooms in the genus Psilocybe.Harmol is the main metabolite of harmine in humans.3 In some plant species such as Peganum harmala, harmol is found most abundantly in the roots.4
