Dynamics of the Headspace Chemical Components of Rosa damascena Mill. Flowers Ana Dobreva

It was monitored the daily dynamics of components in the natural essential oil of Rosa damascena Mill. flowers using static headspace solid phase microextraction technique (sHS-SPME). 37 compounds were identified. It was established that the headspace model was a combination of terpene alcohols: geraniol (0.57 - 32.33 %), citronellol (1.18 - 30.93 %), nerol (0.39 - 8.58 %), menthone (1.46 - 20.20 %) and phenylethyl alcohol (1.32 - 13.36 %), whose presence was highly dependent on day moment and abiotic factors (air temperature, relative humidity, intensity of sunlight and wind) at the relevant time.
