Abstract:
AIM To compare the volatile constituents from the rhizomes and fibrous roots of Atractylodes lancea (Thunb.) DC..METHODS Paraffin sections of rhizomes and fibrous roots were made,and their transverse sections were observed under an optical microscope.Volatile oil was extracted by hydrodistillation.The contents of atractylodin,β-eudesmol,hinesol and atractyline were detected by GC-MS,and the volatile constituents were analysed.Principal component analysis and differential metabolite screening were performed by multivariate statistical analysis software.RESULTS In the transverse section of rhizomes,large oil chambers were observed,while oil cells were found in the fibrous roots.The volatile oil content in the fibrous roots is 24.88％ of that in the rhizomes.A total of 55 common components,2 unique components of rhizomes and 6 unique components of fibrous roots were detected.The ratio of β-eudesmol,hinesol,atractyline and atractylodin in the rhizomes was 22.84∶1.16∶2.78∶1.00,while that in the fibrous roots was 5.59∶0.22∶0.97∶1.00.The volatile constituents in the rhizomes were significantly different from those in the fibrous root,and the groups were well discriminated from each other.Based on the OPLS-DA model,12 differential metabolites including hinesol and β-eudesmol were screened.CONCLUSION The volatile constituents of the rhizomes and fibrous roots of A.lancea are similar,but the contents are different,and the latter has a greater potential for comprehensive utilization.
