Four crystalline substances were isolated: a lactone, m.p. 199°C.; a phytosterol, m.p. 253-256°C., mannitol, m.p. 166°C., and a flavone glycoside which sintered at 194-195°C. and finally melted at 222-224°C. All these substances were tested out on rabbits with negative results.en© 1952 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2017 University of Pretoria.
