found a molecular species at almost the same position (just
between the [EC-EC-EC-EC] tetramer and ECG), which gave gallic
acid and glucose after hydrolysis with tannase and which they
identified as gallotannin. Concerning the procyanidin dimer: the
only possibility that theoretically exists is that it should be
procyanidin B8. Nevertheless, we did not have a reference material
for this species, which is why we assigned this component of peak
31 identity only as a procyanidin dimer
