Extraction and Physicalchemical Properties Analysis of Rose Essential Oil
The essential oil of Rose damascene Miller which was planted first in Jiangxi province was obtained through steam distillation, with a yield of 0.023%. Physical indexes and ma/or compositions of the rose essential oil were analyzed according to ISO 9842 :2003 rose essential oil standard. The results indicated that the oil was yellow liquid with a natural rose flowers smell,having the similar constitution of major compositions to Bulgarian rose oil illustrated in ISO 9842 :2003 standard,physical indexes and the percentage of characteristic compositions met criteria of the standard as well. A total of 73 compositions were identified using gas chromatography-mass spectrometry (GC-MS) combined with heuristic evolving latent projection (HELP) , in which flavor compounds were various and relatively comprehensive. /3-Damascenone was also detected,of which the presence and quantity are considered as the marker for the quality of rose oil.
