Phenolics bind tightly to many proteins (this is the basis for tanning
leather!) and denature them. Phenolics can be sequestered by including PVP
(polyvinylpyrrolidone) or PVPP (??) in the crude extract. There are several
good methods papers on plant extracts that deal with this problem; an older
one is my chapter in Meth Enz 182, 174-193 (1990).
