In consequence, peaks 23
and 24 were tentatively identified as [ECG-(E)C] and [(E)C-ECG].
They eluted first among the monogalloylated dimers and just
between the peak of EC and procyanidin trimer [EC-EC-C],
corresponding thus to those identified by Escribano-Bailo´n et al.
(1992) as [ECG-(4b-8)-EC] (B2-3-G) and [C-(4a-8)-ECG] (B4-30-G),
respectively. Peak 29 was assumed as [(E)C-ECG] and co-eluted with
procyanidin tetramer [EC-EC-EC-EC]. Peak 34 was tentatively
identified as [ECG-(E)C]. It eluted immediately before and almost
overlapped with the digalloylated procyanidin [ECG-(4b-8)-ECG]
(peak 35), and corresponded to those identified by Santos-Buelga
et al. (1995) as [ECG-(4b-6)-C] (B7-3-G). Peak 38 was assumed as
[ECG-(E)C].
