# §21.99. Brucine alkaloid.

- (a) **Identification test.** Add a few drops of concentrated nitric acid to about 10 mg of brucine alkaloid. A vivid red color is produced. Dilute the red solution with a few drops of water and add a few drops of freshly made dilute stannous chloride solution. A reddish purple (violet) color is produced.
- (b) **Melting point.** 178 °±1 °C. Dry the alkaloid in an oven for one hour at 100 °C., increase the temperature to 110° and dry to a constant weight before taking melting point.
- (c) **Strychnine test.** Brucine alkaloid shall be free of strychnine when tested by the method listed under Brucine Sulfate, N.F. IX.
- (d) **Sulfate test.** No white precipitate is formed that is not dissolved by hydrochloric acid when several drops of a 1 N barium chloride solution are added to 10 mL of a solution of the alkaloid.
