Identification of Different Volatile Components in Fresh and Processed Atractylodis Macrocephala Rhizoma Based on GC-IMS
A method was established to rapidly identify the volatile components and to
compare the differences in volatile components between
Atractylodes macrocephala
and processed Atractylodis Macrocephalae Rhizoma from Bozhou,Anhui Province,as well as those from different origins.The volatile compositions of
Atractylodes macrocephala
from Bozhou,Anhui Province,and
Atractylodes macrocephala
from different origins were determined by gas chromatography-ion mobility spectrometry(GC-IMS),the volatile compounds were qualitatively analyzed by using the VOCal software,and the fingerprints of the volatile compositions were established by GC-IMS. The differences in volatile compositions were analyzed by combining the principal component analysis and the least-squares discrimination analysis and the screening of the difference markers with VIP
>
1. A total of 143 volatile compounds were obtained from fresh and processed
Atractylodis Macrocephala
,and 114 of them were identified. The results of GC-IMS fingerprinting showed that the differences in the types of volatile constituents between
Atractylodes macrocephala
and processed Atractylodis Macrocephalae Rhizoma were relatively small but the differences in the contents were obvious. The differences in the types and contents of volatiles of
Atractylodes macrocephala
in different origins were significant. Chemometric analysis classified
Atractylodes macrocephala
and processed
Atractylodis Macrocephalae Rhizoma from Bozhou,Anhui Province,into three categories. The volatile components such as benzaldehyde and ethyl lactate were screened according to VIP
>
1,which can be used as the key components to distinguish the three. The clustering of
Atractylodes macrocephala
from different origins was not obvious,and the volatile components such as
β
-thujene(M) and 3-penten-2-one (M) were screened according to VIP
>
1,which could be used as the key components to distinguish the different origins.The re
search results can offer reference for the quality evaluation and clinical application of
Atractylodes macrocephala.
