title: GC-MS analysis of compounds extracted from buds of Populus balsamifera and Populus nigra.
abstract: The composition of hexane and ether extracts from buds of two poplar species (Populus balsamifera and P. nigra) was investigated by GC-MS method. In hexane extracts, 54 "neutral" compounds were recorded. The greatest amounts of them are sesquiterpenes and n-alkanes. Among 56 components of ether extracts, many aliphatic acids and hydroxyacids were detected. However, the main fraction consists of phenolcarboxylic acids, substituted cinnamic acids, and their esters. It was established that chemotaxonomic differences between Populus balsamifera and P. nigra are observed in the case of both hexane and ether bud extracts.
