choisya ternata/alkaloid

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

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

The accumulation of two dihydrofuroquinoline alkaloids has been studied in seventeen strains of Choisya ternata (Rutaceae) initiated from the same tree. The contents of platydesminium and balfourodinium vary in heavy proportions. The effect of some factors (age of the culture, NAA or glucose

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

Choisya 'Aztec-Pearl', a hybrid of Choisya ternata and Choisya dumosa var. arizonica, had the antinociceptive activity in the ethanol extract (EECA) of its leaves evaluated. Two quinoline alkaloids, anhydroevoxine (A) and choisyine (C), isolated from these leaves were also tested. The results

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

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

Choisya ternata Kunth (Rutaceae) is a plant species used in Mexican folk medicine for its antispasmodic and simulative properties. Recently, we identified a new alkaloid, isopropyl N-methylanthranilate, and a related one, methyl N-methylanthranilate, from the essential oil of this species and have

Two volatile alkaloids, methyl (MMA) and isopropyl N-methylanthranilates (IMA), identified in the essential oil of Choisya ternata Kunth (Rutaceae), have been proven to possess polypharmacological properties (antinociceptive, anti-inflammatory, gastro-, hepato-, nephroprotective activities,

Recently, we identified a new natural antinociceptive alkaloid ternanthranin, isopropyl N-methylanthranilate (ISOAN), from the plant species Choisya ternata Kunth (Rutaceae). In this work we concentrated on the elucidation of its mechanism of action in comparison with two other esters of this acid

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
