Abstract:The optimization of extraction process of curcumin from Curcuma longa L was studied using ethanol as extracting solvent based on single factor level test and orthogonal tests. Results showed that the highest content of the extracted curcumin was up to 4.91% when the curcuma powder was extracted two times with ten time of quantity 75% ethanol solution, each for 3 h. |
Key words:curcumin;orthogonal design;extraction |
