摘要：

Ellagitannins in acetone-water extracts of outer and inner heartwood of European oak were assayed and their M(r) distribution studied by gel permeation chromatography. Ageing of heartwood in the living tree induces darkening of the extract, a decrease in its solubility in cold water and polymerization of ellagitannins.
