The alkaloidal extract of Lobelia inj1ata yields this alkaloid which may be recrystallized from Et20-petroleum ether to give colourless crystals. The hydro_x0002_chloride is obtained as the monohydrate, m.p. 132°C or 154°C (dry); [o:l~o - 76° (H20). A crystalline phosphate has also been prepared, m.p. SO°C but this is unstable and decomposes in the presence of moisture.

ChEBI: Isolobinine is a member of acetophenones.
