Metabolite Identification
Common NameHarmalan
DescriptionHarmalan, also known as dihydroharman, belongs to the class of organic compounds known as harmala alkaloids. Harmala alkaloids are compounds with a structure based on harmaline, harmine, harmalol, harman or a derivative of those parents. These parents are beta-carbolines, consisting of a pyrimidine fused to the pyrrole moiety of an indole to form a pyrido[3,4-b]indole. Based on a literature review a small amount of articles have been published on Harmalan.
