While studying production of phenols, I found that gallic acid (precursor to pyrogallol) is commonly extracted from tannin.
We know tannins are a huge part of the Mimosa root bark so maybe tannins could be extracted from either spent root bark of even before alkaloid extraction.
If tannins were removed, the whole extraction might be more convenient since the presence of tannins make this a "dirty work" (at least for me).
Since I can also make further use of tannin (especially hydrolyzable gallotannins), this took my interest.
Here is a nice publication about tannins in electronic form:
Tannin Handbook
I have currently little time to study this so I am leaving it for discussion for now...
