Journal of the Indian Chemical Society December 1933

1933

As regards the province of chemistry a step was taken in 1932 in the scientific and technical sphere by the entry into activity of the INTERNATIONAL OFFICE OF CHEMISTRY created by the international convention and having its head quarters in Paris. [...] Its first act was the summoning of a Conference of Experts which included the following personalities Messrs F. DONKER DUYVIS Member of the Council of Patents The Hague ; P. DUTOIT Professor at the University of Lausanne ; F. HABER Director of the KaisaWilhelm Insttute for Physikalische Chemie and Electrochemie Berlin; E. HAUSER Member of the Academy of Sciences Madrid ; Ch. [...] The hydrolysis of the anhydrochloride (VI) with strong caustic potash was also tried but the resulting product was the anhydro base (VI OH in place of Cl) which resisted the action of the alkali. [...] As the different authors have used very varying methods for the extraction of the alkaloids it appeared to us of great interest to compare the yield of alkaloids obtained by these different methods from the same sample of bark to test and establish the value of the method evolved by us. [...] The physiological action of the crude bark and its extract in the treatment of intestinal troubles may also be due to this fact as the tannates of the alkaloids would remain undissolved in the acid juices of the stomach and pass on to the seat of disease in the intestines.
