Iron-Curcumin Complex TLC

Using the curcumin without the curcuminoids, a TLC plate was run.  The spot on the left was a 1:3 ratio of Fe(III):Curcumin.  The spot on the right was just curcumin alone.

The two spots that are circled but not colored were present under UV light. 

The Rf values for the two yellow spots are:
Iron-Curcumin complex=0.589
Curcumin alone=0.759

This shows that the complex is more polar than curcumin alone.  This is consistent with the findings from HPLC.
