| Abstract: | Summary The amounts of steryl glycosides (SG) and acylated steryl glycosides (ASG) were investigated in the sapwood, transition zone, inner heartwood and outer heartwood ofPinus sylvestris L. Only traces of both sterol derivates were present and their amounts decreased slightly towards the heartwood. The amount of SG decreased nearly to zero in the inner heartwood but the amount of ASG in the inner heartwood increased slightly. The suitability of enzymatic methods in SG and ASG hydrolysis, and sterol and glucose quantitative determinations, is discussed. |
