Dehydroabietic acid (DHA) (1) is one of the main compounds in Scots pine wood responsible for aquatic and microbial toxicity. The degradation of 1 by Trametes versicolor and Phlebiopsis gigantea in liquid stationary cultures was followed by HPLC-DAD-ELSD. Both fungi rapidly degraded DHA relative to

OBJECTIVE
To research the constituents in needles of Pinus sylvestris.
METHODS
Repeated column chromatography and preparation HPLC are used for compound isolation, and their structures were elucidated on the basis of spectral data analysis.
RESULTS
Six compounds, pinifolic acid (1), 15-oxo-8 (17)
Distribution of low-molecular lipophilic extractives beneath the surface of air- and kiln-dried Scots pine sapwood boards.

During industrial wood drying, extractives migrate towards the wood surfaces and make the material more susceptible to photo/biodegradation. The present work provides information about the distribution, quantity and nature of lipophilic substances beneath the surface in air- and kiln-dried Scots
