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.
采用气相色谱 - 质谱联用（GC-MS）法对两种杨树（香脂杨和黑杨）芽的己烷和乙醚提取物成分进行了研究。在己烷提取物中，记录到54种“中性”化合物。其中含量最多的是倍半萜和正构烷烃。在乙醚提取物的56种成分中，检测到许多脂肪酸和羟基酸。然而，主要成分是酚羧酸、取代肉桂酸及其酯类。已确定在香脂杨和黑杨的己烷和乙醚芽提取物中均存在化学分类学差异。
