Volatile Compounds from Leaf-Buds of Populus Nigra L. (Salicaceae) [link]Paper  doi  abstract   bibtex   
Volatile components from fresh and air-dried leaf-buds of Populus nigra L. (Salicaceae) were isolated by Likens-Nickerson apparatus and analyzed using GC/MS. Forty-eight components (ca. 95\,% of the total isolate) were identified among black poplar bud volatiles. Sesquiterpene alcohols β-eudesmol and α-eudesmol represented 26.3-28.7\,% of the oil. Other major sesquiterpene compounds were γ-selinene (7.6-8.8%), δ-cadinene (7.8-8.6%), α-elemene (3.3-5.2%) and γ-cadinene (3.9-4.2%). Hemiterpenes were also identified (2.2-7.6%). Monoterpenes were present in low percentages (1.6-5.7%). Aliphatic and aromatic alcohols, carbonyl compounds and aliphatic acids were identified among non-terpene volatiles (9.8-13.5%). The fresh buds contained 0.27\,% and dried 0.12\,% essential oil. Air-drying moderately effected the volatiles qualitative and quantitative composition.
