Summary
Bulbine annua, B. asphodeloides, Aloe saponaria and A. africana were investigated phytochemically. Aloe–emodin and chrysophanol were isolated from B. annua and shown to be present in B. asphodeloides by means of paper and thinlayer chromatography. The presence of chrysophanol in A. saponaria and homonataloin in A. africana were detected with the aid of thinlayer and paper chromatography.
The chemotaxonomy of the subfamily Asphodeloideae (Liliaceae sensu Krause) are discussed. The chemical relationship between the genera Bulbine and Aloe are pointed out.
Zusammenfassung
Bulbine annua, B. asphodeloides, Aloe saponaria und A. africana wurden phytochemisch untersucht. In den beiden erstgenannten Arten wurde Aloe–Emodin und Chrysophanol nachgewiesen. In Aloe saponaria fand sich Chrysophanol, in A. africana Homonataloin. Die chemotaxonomischen Beziehungen der Unterfamilie Asphodeloideae werden erörtert.
