The Effect of Temperature, Time and Solvent on an Extraction of Curcumin from Turmeric

Abstract

This research work is a study of the extraction of curcumin from turmeric. Curcumin was
extracted by two organic solvents namely methanol and ethanol. The conditions of extraction are
temperature (250C – 500C) and extraction time (30 minutes to 24 hours). After the extraction at each
condition, the amount of curcumin was analyzed by UV/vis – spectrophotometer. The results showed
that : 1) the optimum condition that gave the highest yield of curcumin ( 80.95mg/ g turmeric or
8.09% by wt..) is at 250C and extraction time of 5 hours for methanol extraction. 2) the optimum
condition that gave the highest yield of curcumin (91.52mg/ g turmeric or 9.15% by wt.) is at 250C
and extraction time of 2 hours for ethanol extraction. 3) the amount of extractable curcumin dcreased
as extraction temperature increased 4) the extractable curcumin can suppress the growth of fungi
Aspergillus Niger effectively.
