Abstract Three new tropanol dimers of mesaconic and itaconic acids and 3α-senecioyloxytropane, together with other known alkaloids, were isolated fromSchizanthus grahamii . The structures of the new compounds were established by spectroscopic and chemical transformations including 2-D long-range 13 C- 1 H correlations.
