Analysis of the chemical compositions of the volatile oil from Rosmarinus officinalis L.planted in Yuzhou, Henan by GC-MS | 河南禹州产迷迭香精油成分的GC-MS分析

chinois. 对禹州引种的迷迭香精油成分进行分析，并与国内其他产区的迷迭香进行比较，为国内迷迭香精油的生产和加工提供依据。用GC-MS技术和峰面积归一化法，参照NIST08质谱库，对禹州产迷迭香的精油成分进行定性和定量分析。从禹州产迷迭香精油中检测到40种物质,并鉴定了25种；含量较高的物质依次为：α-蒎烯(37.150%)、莰烯(18.053%)、桉树脑(12.284%)、樟脑(7.295%)、α-水芹烯(3.820%)、4-蒈烯(3.548%)、β-月桂烯(2.720%)、龙脑(2.273%)、乙酸龙脑酯 (1.632%)、α-松油醇（1.343%）和β-蒎烯（1.760%）等；其中，莰烯、α-水芹烯和β-月桂烯的含量高于国内其他产区，α-蒎烯和樟脑含量居国内前列。与国内其他产区相似，禹州产迷迭香也属于西班牙型；从中提取的精油符合行业规定标准。

anglais. The chemical compositions in the volatile oil of Rosmarinus officinalis L. planted in Yuzhou were compared with those in the other regions in China, to provide a scientific proof for integrative development and utilization of rosemary in our country. The volatile oil was extracted by distillation and analyzed by GC-MS. The relative content of each component was calculated by peak area normalization method. There were 40 peaks separated and 25 of them were identified from the oil of Yuzhou rosemary. The major constituents of the volatiles were α-pinene (37.150%), camphene (18.053%), eucalyptol (12.284%), camphor (7.295%), α-phellandrene (3.820%), 4-carene (3.548%), β- myrcene (2.720%), borneol(2.273%), bornyl acetate(1.632%), α-rerpineo (1.343%) and β-pinene (1.760%), etc. The contents of camphene and β-myrcene were higer than those of other regions; the contents of α-pinene and camphor ranked in the front in China. The main compositions of the volatile oil -from rosemary in Yuzhou are similar to these of other regions in China, which belong to the type of Spanish type.
