[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.

[0043] The detection method is based on 1 H-NMR, specific detection methods include:
[0044] Take 0.20g of dried medicinal powder, accurately weigh it, put it in an Erlenmeyer flask, add 1mL CD respectively 3 OD and 0.3mLD 2 O solution (containing 12.32mg / mLKH 2 PO 4 And 0.04% TSP), sealed, ultrasonically extracted for 30 minutes, taken out, allowed to cool, passed through a 0.45μm microporous membrane, and took 0.60mL of the filtrate into a standard 5mm NMR tube. 1 H-NMR measurement.
[0045] Using deuterated methanol as the frequency internal...
