Example Embodiment

[0039] Example 1

[0040] The components of Gansong medicinal materials from different producing areas were tested. The sources of Ganzong medicinal materials from different producing areas are as shown in Table 1. They are mainly from Ganzi Prefecture of Sichuan Province and are identified as the dried roots and rhizomes of Gansong Nardostachys jatamansi Dc.

Abstract

The invention discloses a method for evaluating the quality of rhizoma nardostachyos medicinal materials based on 1H-NMR. The method comprises the following steps: by taking deuterated methanol as a frequency internal lock, carrying out 1H-NMR detection on the rhizoma nardostachyos medicinal materials; carrying out Fourier transformation on a detected 1H-NMR free induction decay signal to correctchemical shift, carrying out sectional integral on a spectrum in a range of 0.70-8.50ppm, and carrying out normalization processing by a total peak area to obtain signal peak area values correspondingto chemical shift sections; and deducting a signal of a methanol solvent and a peak signal of residual water, and carrying out multivariate statistical analysis on deducted data: forming a matrix bythe deducted data, carrying out scale normalization processing on the matrix, carrying out principal component analysis, and classifying the rhizoma nardostachyos medicinal materials in different production places. According to the method disclosed by the invention, a metabonomics technology is adopted; the 1H-NMR fingerprint spectrums of the rhizoma nardostachyos medicinal materials are established for the first time; and meanwhile, the overall chemical components of the rhizoma nardostachyos medicinal materials are detected and analyzed.
