Analysis of Volatile Constituents in Agrimonia pilosa Ledeb from Different Origins by GC-MS

[Objective]This study aimed to analyze the chemical composition of volatile oils in Agrimonia pilosa Ledeb.from different origins.[Method]HP-5MS capillary columns were used and column temperature was controlled by a program.MS analysis was performed with EI and quadruple mass analyzer.The chemical composition was identified by NIST02 and Wiley275 library,and the relative contents were determined with chromatographic peak area normalization method.[Result]According to GC-MS total ion-current chromatograms,41 chromatographic peaks of volatile constituents in A.pilosa from Zhejiang Province were separated,and 27 chemical compounds were identified,mainly including palmitic acid,cedrol and l-bornyl acetate;47 chromatographic peaks of volatile constituents in A.pilosa from Hunan Province were separated,and 27 chemical compounds were identified,mainly including palmitic acid,(-)-a-selinene andβ-bisabolene;22chromatographic peaks of volatile constituents in A.pilosa from Guangxi Zhuang Autonomous Region were separated,and 13 chemical compounds were identified,mainly including palmitic acid,linoleic acid and caryophyllene oxide.Volatile constituents in A.pilosa from Zhejiang Province and Hunan Province exhibited similar species and contents with several unique compounds,and volatile oils in A.pilosa from these two origins varied significantly from volatile oils in A.pilosa from Guangxi Zhuang Autonomous Region.[Conclusion]This study provided an important basis for the development and utilization of volatile oils in A.pilosa.
