摘要

Seasonal variations in the composition of the essential oils obtained from the same individual (of the same genotype) of Lavandula angustifolia cultivated in Belgrade were determined by GC and GC/MS. The main constituents were 1,8-cineole (7.1-48.4%), linalool (0.1-38.7%), borneol (10.9-27.7%), β-phellandrene (0.5-21.2%) and camphor (1.5-15.8%). Cluster analysis showed that the 21 samples collected each month during the vegetation cycle were separable into three main clades with different compositions of essential oils. In the shoots with flowers, inflorescences and fruits of clade I, linalool is dominant, in the young leaves before flowering and old leaves of clade II, 1,8-cineole is dominant. In the young and incompletely developed leaves of clade III, β-phellandrene is dominant. The composition of the essential oils of lavender depended on the plant part and the stage of development.
