Abstract

DOBREVA, A., A. VELCHEVA, V. BARDAROV and K. BARDAROV, 2013. Chemical composition of different genotypes oil-bearing roses. Bulg. J. Agric. Sci., 19: 1213-1218

 

Gas chromatography and gas chromatography-mass spectrometry was applied for comparison the chemical profile of the essential from three genotypes of oil-bearing roses: Rosa damascena Mill., Rosa alba L. and Rosa № 836/61 (Rosa damascena Mill. x Rosa gallica L.). The analyses identified 60 components. This study reveals that they have the same quality, but different quantitative composition. The main compounds are citronelol (8.76 – 48.24 %), geraniol (8.76 – 23.33 %), nonadecane (7.78 – 18.84 %) and nerol (4.19 – 12.09 %)
