DPPH (2,2-diphenyl-1-picrylhydrazyl) is used for detecting antioxidant
activity of material by reading absorbance at 515 nm. It is strange that
some material shows negative values with DPPH at 515 nm. Does thatl mean
that it is an oxidant?

I am not sure that this is the right place for this question. Please answer
for this. If you know a right place for this kind, tell me about that.
