After the first week, our original filtered extract was almost gone and the diluted mixtures that were made from it were showing that the curcumin left out at room temperature was oxidizing and therefore no longer usable. The new extract is going to be kept in refrigeration when not in use and extractions will be more frequent, most likely weekly.
A larger volume of extract was filtered this time and will be used to attempt to separate the curcuminoids by column chromatography.
