New peltogynoids from Acacia nilotica
The genus Acacia (Leguminosae, subfamily Mimosoideae) includes some 1400 species of trees and shrubs widespread throughout the warm arid and semi-arid regions of the world. Acacia nilotica (L.) Delile belongs to the subgenus Acacia. It naturally occurs in tropical Africa, from Senegal and Egypt southwards to Mozambique and Natal, and also in Asia, from Arabia to India and Burma. A. nilotica is a more or less shrubby tree 5–20m high. This species is widely used in traditional medicine in Africa. Repeated column chromatography over silica gel of the CHCl3 soluble part of the EtOH extract obtained from the stem bark of Acacia nilotica, resulted in the isolation of the two novel peltogynans, acanilol I (1) and II (2), together with the known triterpene lupenone. The structures of the novel compounds were established on the basis of mass spectrometry and NMR experiments [1].
