Protoclones and aggregate clones have been prepared from 5 callus strains of C. ternata chosen for their dihydrofuroquinoline-accumulating capacities in a population of well-established strains. The results show that it is possible to obtain cell lines which accumulate higher alkaloid contents than

A range of seventeen quinoline alkaloids, involving several types of oxidations during their biosynthetic pathways, have been isolated from leaves of Choisya ternata. In addition to the nine known quinoline alkaloids, eight new members of the furoquinoline family, derived mainly from prenylation at
Variability in tissue cultures of Choisya ternata. III comparing alkaloid production in cell lines obtained by various strategies.

Callus cultures of Choisya ternata have been prepared by different strategies: aggregate clones, subclones and protoclones obtained from well-established strains; protoclones obtained from mesophyll tissue; cultures transformed by Agrobacterium tumefaciens. All of them show high variability in their

BACKGROUND
Mexican people employed infusion of leaves of Choisya ternata Kunth for their antispasmodic and "simulative properties".
OBJECTIVE
In the present study the detailed GC and GC-MS analyses of the essential oil of Choisya ternata Kunth (Rutaceae) were performed. The presence of a minor

One novel compound was isolated from the hexane extract of Choisya ternata Kunth. leaves, choisyaternatine (1), together with the known compounds tecleamaniensine A (2), lup-20(29)-en-3β-ol (lupeol) (3), lup-20(29)-en-3β,24-diol (4), β-sitosterol glucoside (5), and skimmianine (6), plus the
A study of the analytical behaviour of selected synthetic and naturally occurring quinolines using electrospray ionisation ion trap mass spectrometry, liquid chromatography and gas chromatography and the construction of an appropriate database for quinoline characterisation.

Mass spectral fragmentation of quinoline alkaloids of significance in plants has been investigated using electrospray ionisation ion trap mass spectrometry (ESI-MS(n)) with a view to characterisation of molecules of unknown structure isolated from these natural sources. This investigation has led to

The absorption and fluorescence properties of six furoquinoline or pyranoquinoline alkaloids extracted from Rutaceae plants are described. These properties are related to the molecular structure and used for the fluorometric determination of two of them (platydesminium and balfourodinium) in Choisya
