Summary

The extractives of clear and sticker stained sapwood from sugar maple (Acer saccharum Marsh.) were isolated and screened for low molecular-weight phenols, which could be involved in the formation of sticker stain. Scopoletin (7-hydroxy-6-methoxycoumarin) was identified as the major low molecular-weight free phenol in the samples studied. This compound, which has not previously been reported in extractives from maple wood, was quantified in stained and clear samples. Additionally, the two major fatty acids present were identified as palmitic acid and linolenic acid, and the two major sterols as stigmasterol and sitosterol.
