title: Volatile constituent distribution of Prangos coryombosa Boiss at two stages of growth.
abstract: The volatile constituents obtained by hydrodistillation of the aerial parts of Prangos coryombosa at the vegetative and flowering stages were analysed by GC and GC-MS. Twenty-one and 28 compounds were identified from the oils obtained from the plant's aerial parts at the vegetative and flowering stages, respectively. The oil from the vegetative stage was dominated by β-elemene (22%) and spathulenol (12.5%), whereas the oil from the flowering period was characterised by β-elemene (40.7%) and kessane (10.7%). The main compounds of the oil at the flowering stage were isolated by TLC and their structures were elucidated by (1)H and (13)C NMR. The results have ecological and taxonomical significance.
