Polyvinylpyrrolidone (PVP) and polyvinylpolypyrrolidone (PVPP) I 
beleive are used to remove poly-phenolic compounds found in plant 
tissues. These compounds often inhibit subsequent enzymatic 
manipulation of the n;ucleic acid, ex. RE digestion or PCR. The 
literature claims PVP and PVPP remove humic and fulvic acids which 
likewise inhibit PCR. These two compounds are commonly found in samples 
containing decaying plant material.
