Study of the volatile constituents in Atractlodesm acrocephala Koidz by gas chromatography-mass spectrometry and combined chemometric methods

摘要

A method for the study of the volatile components in Atractlodesm acrocephala Koidz from different sources with combined chemometrics methods was developed. After the volatile components in Atractlodesm acrocephala Koidz from two different locations were detected by GC-MS, the qualitative and quantitative analysis of the volatile components of Atractlodesm acrocephala Koidz from Tiantai was conducted with SFA. Then, the common peak in Atractlodesm acrocephala Koidz sample from Xinan was extracted with orthogonal projection method. Among the identified components, there were 37 components coexisting in the studied samples although the relative content of each component showed difference to some extent. The obtained results can provide useful information for the developing of fingerprint of Atractlodesm acrocephala Koidz. It also can be used to compare the sameness and differences of Atractlodesm acrocephala Koidz from different sources and for quality control of Atractlodesm acrocephala Koidz.
