摘要：

High concentrations of gallotannins were found in young leaves of mountain birch trees (Betula pubescens ssp, tortuosa). Phenolic compounds were separated by HPLC and their UV spectra were recorded with a diode array detector. On the basis of these data, 11 individual gallotannins were preliminary identified in birch leaves. Strong and positive correlations were found between concentrations of these gallotannins and the protein precipitation capacity of extracts. Content of gallotannins decreased rapidly with leaf growth and maturation. Among-tree variation was high and significant for most individual gallotannins. Intracellular organization and metabolism of gallotannins in birch leaves are discussed. (C) 1997 Elsevier Science Ltd.
