Abstract
Composition and content of terpene compounds in pine bark (Pinus sylvestris) after various storage
periods were studied by GLC-MS. Resin acids were found to be the main diterpenoic compounds in
the bark. Content of dehydroabietic acid in initial bark is 0.6 g/kg and it decreases three-fold after one
year of storage. High activity of pine bark after various storage periods towards risogenesis of wheat
(Triticum aestivum) was discovered. Strong correlation (r = 0.89) between growth promoting activity
of pine bark and content of dehydroabietic acid in it was found
