Abstract
We have used 1H and 13C NMR spectroscopy to study the composition of pine resin balsams from Scotch pines grown in different regions of the Republic of Belarus. We have established that their chemical composition does not depend very much on the region where they are grown or the level of contamination of the forests by radioactive and industrial emissions. Prolonged storage of the balsams leads to a substantial change in their compositions, due to isomerization of the resin acids.
