The extraction of quinine bark involves harvesting the bark from the cinchona tree, which is native to South America. The bark is then dried and ground into a powder. The powder is then mixed with a solvent, such as water or alcohol, to extract the quinine alkaloids. The mixture is then filtered to remove any solid particles, leaving behind a solution containing quinine. This solution is further processed to isolate and purify the quinine alkaloids, which are then used in the production of medications like antimalarial drugs. **

HPLC involves separating the components of the tonic water and then quantifying the amount of quinine present based on its specific retention time and peak area. Spectrophotometry, on the other hand, measures the absorption of light by quinine at a specific wavelength, allowing for the quantification of its concentration in the tonic water. Both methods provide accurate and reliable results for determining the quinine content in tonic water. **
