This alkaloid is obtained from the mother liquors from Anhalonium Lewinii
Hennings as the crystalline (+ )-tartrate. The free base is a colourless oil having
[α]20D + 20.7° (MeOH) and characterized as the 2:4: 6-trinitrobenzoyl derivative,
m.p. 259-2600 C; [α]24D + 39.7° (MeOH). It has been identified by comparison
with the (+ )-component from the resolution of synthetic (±)-anhalonidine 0-
methyl ether. The (-)-isomeride has [α]D - 20.1° (MeOH) and gives the corresponding
2:4:6-trinitrobenzoyl compound, m.p. 259-2600 C; [α]23D - 43.7°
