Abstract The alkaloid composition of leaves of Dicraeopetalum stipulare Harms was examined by capillary gas chromatography (GLC) and GLC-mass spectrometry. 5,6-Dehydrolupanine, anagyrine and cytisine figured as major and baptifoline, N -methylcytisine, lupanine, ammodendrine, N -formylcytisine and N -acetylcytisine as minor alkaloids. Sparteine, rhombifoline and 6β-hydroxylupanine were detected in trace amounts. Two new alkaloids were tentatively identified as 10-oxolupanine and 17-oxolupanine. 
A phytochemical study of the quinolizidine alkaloids from Genista tenera by gas chromatography-mass spectrometry.
Gas chromatography coupled with mass spectrometry has been used to analyse the alkaloids present in the aerial parts of Genista tenera, characterisation of the constituents was based on comparison of their Kovats retention indexes and electron impact-mass spectrometric data recorded on-line with those of reference compounds and literature data.

Preparative Separation of Alkaloids from Stem of Euchresta tubulosa Dunn. by High-Speed Counter-Current Chromatography Using Stepwise Elution
Alkaloids in the stem of Euchresta tubulosa Dunn were isolated and purified by high-speed counter-current chromatography (HSCCC) using stepwise elution and the applicability of the mode was verified. Expand
Quinolizidine alkaloid status of Acosmium s.s., Guianodendron and Leptolobium, the segregate genera of Acosmium s.l.
The quinolizidine alkaloid status of Acosmium s.s, Guianodendron and Leptolobium agrees with their segregation from Acos m.l.s. and the exclusion from the genistoid clade of legumes, as suggested by morphological characters and molecular phylogenies. Expand
