A furoquinoline alkaloid present in Flindersia dissosperrna and F. rnaculosa Lindl., the base crystallizes from MeOH or EtOH as colourless needles. The base is characterized as the hydrochloride, m.p. 205-2100 C (dec.) which is best obtained from dilute HCI and the picrate, m.p. 198°C (dec.). The structure has been determined mainly on the basis of the fragmentation pattern of the mass spectrum.

ChEBI: Maculine is an oxacycle, an organonitrogen heterocyclic compound and an organic heterotricyclic compound.
