[Objective] To establish a rapid analysis method for volatile components in RADIX ADENOPHORAE,to analyze and compare the differences of RADIX ADENOPHORAE in different production areas,and to obtain the characteristic distribution of volatile components and the rapid information identification mode of production areas. [Methods] Volatile components were extracted from RADIX ADENOPHORAE by solid phase microextraction( SPME),and were analyzed by GC-MS. The relative content of each component was calculated by peak area normalization method; and statistical analysis was carried out by SPSS 18. 0 software based on principal component analysis( PCA) and cluster analysis( CA). [Results] A total of 41 chemical components of RADIX ADENOPHORAE were identified from RADIX ADENOPHORAE grown in different areas,mainly including aldehydes,terpenes,organic acids and alcohols. Among them,isovaleraldehyde,hexanal,α-pinene and caprylic aldehyde were common volatile components in RADIX ADENOPHORAE. Besides,RADIX ADENOPHORAE grown in Shennongjia and Jiangsu had abundant terpenoids. [Conclusions]The established method was simple and was suitable for the rapid identification and analysis of RADIX ADENOPHORAE. PCA and CA could effectively distinguish RADIX ADENOPHORAE grown in different areas. The production areas were divided into five categories by cluster analysis. Research results provided references for the variety comparison and quality control of RADIX ADENOPHORAE.
