| Abstract: | Commonly used alkaloidal salts may be titrated accurately with acetous HClO4 in non-aquous media in semi-micro scale using crystal violet as visual indi- cator.The method gave results compared favorably with those obtained by usual method in the respect of its simplicity,rapidity and reproducibility. A modified method was suggested to facilitate the extraction of alkaloidal salts as such from tablets by means of water,aqueous alcohol or other strong polar solvents. |
