玫瑰精油的提取和理化性质分析

采用水蒸汽蒸馏法从江西首次引种的大马士革玫瑰(Rose damascene Miller)花中提取获得精油,得率为0.023％.按照ISO 9842:2003玫瑰精油标准方法测定精油的物理指标和主要组分,结果表明:该精油为黄色液体,具有天然的玫瑰花香,其物理指标和特征组分的百分含量符合标准要求,且主要组分构成与标准中保加利亚玫瑰精油相似.气相色谱-质谱(GC-MS)结合直观推导式演进特征投影法(HELP)分析江西大马士革玫瑰精油,共鉴定出73个组分,其中香质组分较为完整,高品质玫瑰精油的标识成分β-突厥烯酮也被检出.

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 major 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.β-Damascenone was also detected,of which the presence and quantity are considered as the marker for the quality of rose oil.
