The tropane alkaloids from three Western Australian Anthocercis species

Abstract

The major alkaloid of both Anthocercis viscosa R. Br. and A. fasciculata F. Muell. has been identified as (-)-hyoscyamine (I). A trace of the same partly racemic base has been isolated from A. littorea Labill., together with meteloidine (II), but the major alkaloid present in this species is littorine (III) which has been shown to be R(-)-3α-(2-hydroxy-3-phenylpropionyloxy)tropane.     Rutin and ursolic acid have also been isolated from A. viscosa.
