title: Volatile oil constituents and antibacterial activity of different parts of Falcaria vulgaris Bernh. growing wild in two localities from Iran.
abstract: The chemical composition of essential oils obtained by hydrodistillation from the flower, leaf and stem of Falcaria vulgaris Bernh., which is endemic to Iran, were analysed by GC and GC/MS (samples were from two different localities: A from Ardabil and B from Khalkhal). α-Pinene was the major constituent in all the three oils (flower, leaf and stem) from sample A (43.8%, 33.0% and 50.9%, respectively). The oil of F. vulgaris flower was characterised by a higher amount of β-caryophyllene (25.2%) and 1,8-cineole (12.8%) among the eight components comprising 96.2% of the total oil detected. α-Terpinyl acetate (23.2%) and limonene (14.4%) predominated in the leaf oil. In the oils of sample B, α-pinene (16.1% in the flower oil, 31.5% in the leaf oil and 34.5% in the stem oil) was the major compound. Limonene (14.2%) and germacrene D (32.1%) were also the main constituents found in the leaf oil from sample B. α-Terpinyl acetate (21.9% in the leaf oil) and limonene (29.8% in stem oil) were the other major compounds obtained from this sample. Antibacterial activity was determined by the measurement of growth inhibitory zones.
