Abstract：Objective:To explore the differences in odor and volatile components of Aucklandiae Radix from different origins.Methods:Nineteen batches of Aucklandiae Radix were collected.The odor of samples was analyzed by PEN3 electronic nose system.Headspace gas chromatography-mass spectrometry(HS-GC-MS)was used to detect and analyze the volatile chemical components of Aucklandiae Radix.Principal component analysis(PCA)was used to identify the origins and chemical components of samples.Differential components were screened based on the partial least squares discriminant analysis(PLS-DA)and principle of variable importance in projection(VIP)greater than 1.Person correlation analysis was conducted between differential volatile components and electronic nose sensors.Results:The four sensors of the electronic nose had relatively high response.Fifty-three,thirty-six,twenty-seven and thirty-three chemical components from Yunnan,Gansu,Sichuan,and Hubei were identified respectively by HS-GC-MS.The main material basis for the generation of Aucklandiae Radix was speculated.Conclusion:The origin of medicinal herbs can be well distinguished by electronic nose combined with HS-GC-MS.The selected differential compounds and odor substances provide reference for distinguishing the origin of Aucklandiae Radix and evaluating the odor characteristics.
