Variation among three Crinum species in alkaloid content
2003
Dilute hydrochloric acid solution extraction, followed by gas chromatographic analysis, was used to investigate the interspecific variation in the alkaloid content of three Crinum species, C. bulbispermum, C. macowanii, and C. moorei over two consecutive years. The identified alkaloids showed that C. moorei had the highest levels of all individual alkaloids, except crinamine, when compared to C. bulbispermum and C. macowanii. The detected alkaloids can be used to make a chemotaxonomic distinction between C. moorei on the one hand and C. bulbispermum and C. macowanii on the other. The results suggest that C. macowanii is more closely related to C. bulbispermum.
