Using Commercially Produced Curcuminoids

To ensure the purity of the samples that we extracted from the turmeric powder directly, we used commercially available samples from Sigma-Aldrich.  The first sample tested was a mixture of all three curcuminoids.  5mg of the commercially available powder was added to ethanol to make 100ml of solution that was tested by UV and HPLC against the solution extracted from the turmeric powder.  This confirmed that our original sample extracted from the turmeric was just as pure as the commercially available powders.  The benefit of using the powder was that the exact molarity of the solution was known.
