  • Abstract:

    Leaves and stems of the plant, Pachystigma pygmaeum (gousiektebossie), collected at Kaalfontein on 20th October, 1950, were subjected to a chemical investigation. 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.
