| dc.description.abstract | Curcumin is a pigment in Curcuma domestica Valet, which has an orange yellow crystal appearance, and commonly being used as a colouring agent.
Extraction method which is used in extracting curcumin from Curcuma domestica
Valet isone stage extraction. This research studied a multi stages extraction of
curcumin from Curcuma domestica Valet. The purposes of this research is to find
the best condition in extracting curcumin using multi stages extraction method, to
increase the efficiency rate in curcumin extraction. This research used ethanol as a
solvent, and effect from variables such as extraction time, solvent concentration,
and number of extraction stages are observed. Extraction times are 60 minutes,
120 minutes, and 180 minutes. Variations of ethanol concentration are 50%, 70%,
and 96%. Stage numbers of extraction are two stages extraction and three stages
extraction. Extracts of curcumin are examined with qualitative analysis and
quantitative analysis. The best condition of multi stages curcumin extraction is
determined based on yield and content of curcumin. The maximumyieldobtained
inthis study was12% withconditions 180 minutes extraction time, 96% ethanol
concentration, and two stages extraction. The highest content of curcumin
obtained is 16% with conditions 180 minutes extraction time, 96% ethanol
concentration, and three stages extraction. Content means a fraction of yield.
These results show that increase inextraction time, solvent concentration, and
stage numbers of extraction will increase the yield and content of curcumin
extracted from Curcuma domestica Valet. | en_US |
