Two tetrahydroquinoline alkaloids have been isolated from the bark of Galipea officinalis Hancock. Their structures have been established by spectroscopic methods. The compounds were named angustureine (1,2,3,4-tetrahydro-2(n-pentyl)-1-methylquinoline) and galipeine (2-[(3'-hydroxy-4'-methoxy-phenylethyl)]-2,3,4-tetrahydro-1-methylquinoline).
