The crucial question for the final chromatographic analysis is, which procyanidins are to be expected in a given matrix. Naturally occurring procyanidins predominantly consist of either (-)-epicatechin or (+)-catechin. In the (-)-epicatechin series procyanidins B2, B5, Cl and an (-)-epicatechin tetramer co-occur (i.e. in Crataegus sp.), while principal components in the (-t-)-catechin series are procyanidins B3, B6, C2 and a (+)-catechin tetramer (i.e. in Salix sp.). Predominance of procyanidins B1 (i.e. in Rubus sp.) or B4 (i.e. in Sorghum sp.) is relatively seldom in the plant kingdom. The main procyanidins are always accompanied by the...

The hydrated wood cells contain amorphous cell wall remnants that can be seen by comparison with Figure 15B. B. Polarized light microscopy photomicrograph. The birefringent primary wall-middle lamella complex can be seen in the hydrated wood cells.
