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.
