L. amara Blanco). The base is a quinolone derivative and crystallizes as colourless needles from AcOEt. It is dextrorotatory having [α]24D + 30.1 ° and [α]24436 + 81.8°. Boorsma gives a specific rotation of [α]28D + 31.6°. The solutions of the alkaloid show a weak blue fluorescence in artificial light. A crystalline perchlorate is known, m.p. 146-8°C and 193-5°C after intermediate solidification. This salt is also dextrorotatory with [α]2558925436+ 60.7°. The structure has been demonstrated to be 3-(2-hydroxy-3- methylbutyl)-4: 8-dimethoxy-l-methyl-2-quinolone. The alkaloid described under this name by Dieterle and Beyl appears to be identical with lunamarine (q.v.).
