I am not sure if this is the right place for this, but I am searching for an article from 1998. The title is: "Spectrometric pKa determination of
daphnetin, chlorogenic acid and quercetin" writen by Sauerwald, N., Schwenk, M., Polster, J.and Bengsch, E.
I searched my university library database but had no luck.
Anyone knows any good sources for finding this article?
Thanks in advance.
