Chemical examination of the bark of Alangium lamarkii Thwaites. Isolation of the alkaloid alangine

1. From the bark of Alangium Lamarkii Thwaites, a new alkaloid has been obtained crystallising in long yellow glistening prisms, m.p. 205-08°C. The molecular formula of the alkaloid has been found to be C19H25O2N. This has been named "Alangine". 2. The alkaloid has been found to be a monoacid base containing one methoxy group but no >N-CH3 group. 3. The alkaloid which is dextrorotatory easily gives crystalline salts with organic and inorganic acids and the hydrochloride, sulphate, nitrate, iodide, acetate, tartrate, oxalate, picrate and iodomethylate have been prepared and described
