ABSTRACT

Objective To explore the relationship between the volatile components in Angelicae Sinensis Radix from different regions of Gansu Province and its growing environment with metabolomics based on GC-MS. Methods The GC-MS method was used for detecting the volatile components in Angelicae Sinensis Radix from 31 different regions in Gansu province, and principal component analysis (PCA) and partial least squares (PLS) methods were used for analyzing and evaluating its relationship with the growing environment. Results The results of PCA showed that the volatile components in Angelicae Sinensis Radix from different regions in Gansu province were related to the altitude and the soil types. The PLS method could divide 31 samples of Angelicae Sinensis Radix from different regions in Gansu Province into three groups according to the difference of altitude. There were significant differences in the volatile components in the samples taken at different altitude regions. After analyzing linear loading plots from PCA and PLS, 11 charateristic components were screened out, including 7 compounds were identified by the retrieval of NIST11 database. Conclusion The volatile components in Angelicae Sinensis Radix from different regions in Gansu Province are closely related to the altitude and the soil type.
