Abstract

A method of designing solvents for the optimal extraction of bio-active ingredients from natural resources was developed using an alcohol-water binary solvent. The target bio-active ingredient of polyphenols, anti-oxidation and anti-tyrosinase ingredients exhibited different dependency of extraction efficiency on the alcohol species (methanol, ethanol, n-propanol and i-propanol) and composition of binary solvent. Using the solubility parameter, the extraction efficiency of the bio-active ingredients was correlated with the solvent polarity. As a result, the optimal solvent polarities for the extraction of polyphenols, anti-oxidation and anti-tyrosinase ingredients were predicted as 38.5, 37.33, and 33.0 [MPa1/2], respectively. These predictions also agreed well with the optimal solvent conditions of the water-alcohol mixtures depending on the alcohol species and composition. Plus, the correlation was confirmed with model solvents designed using other solvent species, including acetone and ethylene glycol.
