„Angostura bark (from Galipae officinalis, Rutaceae) contains two unstable bitter principles, which are isolated in the form of their crystalline hexaacetates. The structure of the bitter principle has been shown to be 3,5-Dihydroxy-5-ethoxy-2-syringoyl-1-methyl-4-O-β-d-glucopyranosyl-cyclopentane, the bitter principle 2 to be 3,5-Dihydroxy-5-ethoxy-2-vanilloyl-1-methyl-4-O-β-d-glucopyranosyl-cyclopentane.“

The bark of G.officinalis contains tetrahydroquinoline alkaloids like angustureine (1,2,3,4-tetrahydro-2(n-pentyl)-1-methylquinoline), cuspareine, galipinine (2-[(3′-hydroxy-4′-methoxy-phenylethyl)]-2,3,4-tetrahydro-1-methylquinoline) and N-methyl-2-propyl-tetrahydroquinoline.
