Spruce sulphite liquor was extracted with butyl acetate. By means of solvent fractionation, chromatography, and countercurrent distribution, vanilloyl methyl ketone, vanillin, dihydroconiferyl alcohol, 3,3′-dimethoxy-4,4′-dihy-droxystilbene, and a new phenolic compound, C20H24O5, were isolated and identified.
