The cladistic relationships between Schizanthus species, based primarily on morphology, and chemical characters when available are presented. In this investigation we did not find supporting evidence for the theories ...

The alkaloid profile of the aerial parts of Schizanthus tricolor Grau et Gronbach was investigated by GC-MS. Seventeen alkaloids were detected and are reported in this species for the first time. They were identified by ...

Three new tropanol dimers of mesaconic and itaconic acids and 3α-senecioyloxytropane, together with other known alkaloids, were isolated from Schizanthus grahamii. The structures of the new compounds were established by ...

Two new hygroline and tropane alkaloids, 4-hydroxybenzenepropanoylhygroline (1) and 3α,4β-dihydroxy-6β-angeloyoxytropane (2) have been isolated from the aerial parts of Schizanthus hookeri and S. tricolor, respectively, ...

Six new tropane alkaloids have been isolated from the leaves of the endemic Chilian plant Schizanthus litoralis (Solanaceae). The new structures include a new tropanol dimer of itaconic acid together with 6β- senecioylox ...

Tropine, a pair of diastereoisomeric hygrolines and two new tropane alkaloids; 3α-senecioyloxytropan-6β-ol and 6β-angeloyloxytropan-3α-ol, were isolated from roots of Schizanthus hookeri. © 1980.

Three different pollination syndromes (bee, hummingbird and moth-pollination syndromes) have been described for the different species of the genus Schizanthus Ruiz & Pav. (Solanaceae). Two closely related species from a ...

Two new tropane alkaloids schizanthine Y and schizanthine Z have been isolated from the methanol extract of the leaves of Schizantus porrigens, in addition to the known compounds (-)-6β-angeloy-loxytropan-3α-ol and ...

The relative lack of specificity of atropine as a competitive antagonist of muscarinic receptors is a frequent cause of undesirable parasympathetic side effects. Consequently, new tropane alkaloids with potentially greater ...

Chemical investigation of the alkaloid extract of the aerial parts of Schizanthus tricolor led to the targeted isolation of 26 hygroline derivatives of which 20 were fully characterized. They have not yet been described ...
