Abstract: Gas chromatography-mass spectrometry (GC-MS) and the chemometric resolution method (alternative moving window factor analysis, AMWFA) were used for comparative analysis of volatile constituents in herbal pair (HP) flos lonicerae-caulis lonicerae (FL-CL) and its single herbs. The temperature-programmed retention index (PTRI) was also employed for the identification of compounds. In total, 44, 39, and 50 volatile chemical components in volatile oil of FL, CL and HP FL-CL were separately determined qualitatively and quantitatively, accounting for 87.22%, 94.54% and 90.08% total contents of volatile oil of FL, CL and HP FL-CL, respectively. The results show that there are 32 common volatile constituents between HP FL-CL and single herb FL, 33 common volatile constituents between HP FL-CL and single herb CL, and 10 new constituents in the volatile oil of HP FL-CL.
