The constituents of the Matricaria recutita L. essential oil from Yongdeng of Gansu were analyzed by GC/MS and MassWorks? software. The suitable chromatography and mass spectrometry conditions for the analysis of chamomile essential oil were determined by comparing the separation results in two different polarity columns. 35 kinds of compounds were identified. MassWorks can determine the accurate molecular weight of compounds and provide important basis for the low-resolution quadrupole mass spectrometer to identifying the elemental compositions and the structure of compound, as well as provide a new technical means for the component analysis of the essential oils.%采用气相色谱-质谱联用(GC/MS)技术,结合MassWorksTM质谱解析软件,对产自甘肃省永登县的洋甘菊(Chamomila recutita L.)精油成分进行分析.对两种不同极性的色谱柱进行分离比较实验,确定了适合于洋甘菊精油分离分析的色谱条件和质谱条件,解析并确定出精油中的35种化合物.MassWorks软件在低分辨率质谱上可对化合物分子质量实现精确测量,为低分辨四极杆质谱确定化合物的元素组成和解析化合物结构提供重要依据,同时也为植物精油的成分分析提供新的技术手段.
