采用气相色谱-质谱(GC-MS)法分离测定了药对麻黄-羌活、单味药麻黄和羌活的挥发油,并对其重叠色谱峰采用化学计量学解析法进行了分辨,得到药对和各单味药的纯色谱曲线和质谱.药对麻黄-羌活、单味药麻黄和羌活分辨出的色谱峰,通过质谱库对其进行定性,分别得到58,51和52个定性结果,占总含量的83.75%,88.70%和80.79%.实验结果表明:药对麻黄-羌活中挥发油化学成分有40种来自羌活,13种来自麻黄,新产生了10种化合物.

Determination of volatile components in drug pair (DP) Herba Ephedrae-Rhizoma seu Radix Notopeterygii (HE-RsRN), single drug HE and RsRN was performed using two-dimensional gas chromatography-mass spectrometry (GC-MS) data coupled with chemometric resolution method (CRM). With the help of CRM, the two-dimensional data obtained from GC-MS instruments were resolved into a pure chromatogram and a mass spectrum of each chemical compound. Using these methods to process two-dimensional data, 51, 52, and 58 volatile chemical components in essential oil of HE, RsRN, and DP HE-RsRN were respectively de...
