Ammodendron Conollyi Bunge (Leguminosae) is a small tree found in the deserts of Central Asia. Although its stem and branches are almost devoid of alkaloids, its leaves contain a considerable quantity (1.8% of the dry weight). The crude, oily alkaloid may be separated by vacuum distillation into three fractions and a residue (463). The lower boiling fraction consists of d-sparteine while the fraction b.p. 185-200°/4 mm., consists mostly of a new alkaloid which is named ammodendrine. The ratio of d-sparteine to ammodendrine varies with the time of harvesting (461). In plants collected in July, this ratio was 5 1, while in material collected in August and September, it was 2 3. 

Another compound, an alkaloid closely resembling the nicotine alkaloid anabasine, has been found in the Leguminosae, namely, ammo-dendrine, obtained from Ammodendron conollyi.
