The sapwood and heartwood extractives of Douglas fir and the tall oil in the kraft black liquor were characterized. On pulping, isomerization and conversion of conjugated resin acids to dehydroabietic acid was observed. Recovery of both fatty and resin acids from pulping was lower than predicted from the extractive composition. High contents of sterol esters (about 35%) and a new triterpene alcohol are reported. The lightwood-inducing effect of paraquat was limited.
