Mark record


Methyl gallate was found in ethanolic extracts of red maple (Acer rubrum L.),silver maple (A. saccharinum L.) and sugar maple (A. saccharum Marsh) leaves,but more was present in methanolic extracts. The increased amount of methylgallate in methanolic extracts was accompanied by a disappearance of »i-digallate. It is concluded that only some of the methyl gallate detected in methanolic extracts is an artefact as a result of methanolysis of m-digallatc. Its presence in ethanolic extracts is evidence that it is also a natural constituent of maple leaves.
