[Lehrbuch der Biologischen Heilmittel, Gerhard Madaus, 1938]

Bark extracts have been used as a bittering agent in the preparation of liqueurs. Products bearing the name Angostura are not necessarily prepared from the bark extract but, for example, gentian root or other bitter drugs.

„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, galipeine (2-[(3′-hydroxy-4′-methoxy-phenylethyl)]-2,3,4-tetrahydro-1-methylquinoline) and N-methyl-2-propyl-tetrahydroquinoline.

Of the tetrahydroquinolines from G.officinalis, galipinine yielded the best antimalarial effect (IC50: 0.09 - 0.9 μg/ml) on chloroquine-resistant strains of P. falciparum.
