Abstract: | Analysis of volatile components in herbal pair (HP) herba schizonepetae-ramulus cinnamomi (HS-RC),single herb HS and RC was carried out by gas chromatography-mass spectrometry (GC-MS) data and chemometric resolution method (CRM).The two-dimensional data obtained from GC-MS instruments were resolved into a pure chromatogram and a mass spectrum of each chemical compound by CRM.In total,47,61 and 51 chemical components in volatile oil of HS,RC,and HP HS-RC were respectively determined qualitatively and quantitatively,accounting for 90.52%,88.37%,and 88.72% total contents of volatile oil of HS,RC,and HP HS-RC,respectively.The number of the volatile components of HP HS-RC is almost the addition of that of two single herbs,but their relative contents are changed. |
