PCA removal of these peaks gave the same result as that obtained using CDCl 3 and allowed species distinction. The 1H NMR spectra using CD 3OD contained confounding sugar peaks. When CDCl 3 extracts were utilized, the chemometric analysis enabled the identification and classification of Atractylodes species according to their composition of major sesquiterpene compounds. Principal component analysis (PCA) using 1H NMR spectra of extracts with two solvent systems (CD 3OD, CDCl 3) was performed. lancea cultivated in Japan had a type 5, hybrid DNA sequence. Our samples had nucleotide sequences as previously reported, except that part of the A. The ITS region of the nuclear rDNA was sequenced for five species, A. 1H NMR metabolic profiling of DNA-authenticated, archived rhizomes of the genus Atractylodes was performed for genetic and chemical evaluation. Identifying different species of the genus Atractylodes which are commonly used in Chinese and Japanese traditional medicine, using chromatographic approaches can be difficult.
