Title: Tall oil precursors of Douglas fir

Author: Foster, Daniel O.; Zinkel, Duane F.; Conner, Anthony H.;

Date: 1980

Source: Tappi. Vol. 63, no. 12 (Dec. 1980): pages 103-105.

Publication Series: Miscellaneous Publication

Description: The sapwood and heartwood extractives of Douglas fir [Pseudotsuga menziesii (Mirb.) Franco] 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. Unusually high sterol esters and a new triterpene alcohol are reported. The lightwood-inducing effect of paraquat is limited.

Keywords: Pseudotsuga menziesii, extractives, tall oil, paraquat, fatty acids, oleoresins, precursors, resin acids, lightwood, triterpenes, nonsaponifiables
