School of Chemistry and Chemical Engineering, Central South University, Changsha , China) Abstract: Comparison analysis of common volatile constituents in herbal pair (HP) radix saposhnikoviae (RS)-rhizoma seu radix notopterygii (RSRN) and its single herbs was performed using two-dimensional gas chromatography-mass spectrometry (GC-MS) data coupled with alternative moving window factor analysis (AMWFA). In total, 79, 70 and 74 volatile chemical components in volatile oil of RS, RSRN and HP RS-RSRN were separately determined qualitatively and quantitatively, accounting for 85.81%, 87.35% and 86.76% of total contents of volatile oil in RS, RSRN and HP RS-RSRN respectively. The results show that there are 44 common volatile constituents in HP RS-RSRN and single herb RS, and 53 common volatile constituents in HP RS-RSRN and single herb RSRN. The experimental results also show that the volatile chemical components in HP RS-RSRN are mainly from single herb RSRN.
