Alkaloids
... 1- Direct titration of the alcoholic solution of the alkaloidal residue with standard acid, or 2- Back titration by dissolving the residue in a known amount of standard acid and back titration of residual acid against standard alkali. Non-aqueous titration: This method is suitable for determination ...

Decaffeination
Decaffeination is the removal of caffeine from coffee beans, cocoa, tea leaves and other caffeine-containing materials. While soft drinks which do not use caffeine as an ingredient are sometimes described as ""decaffeinated"", they are better termed ""non-caffeinated"" because decaffeinated implies that there was caffeine present at one point in time. Decaffeinated drinks contain typically 1–2% of the original caffeine content, and sometimes as much as 20%. Decaffeinated products are commonly termed decaf.
