Abstract:
The inundation of Cordyceps sinensis counterfeits in the market makes it difficult to identify. In this study, 21 batches of wild C. sinensis from 3 different regions, 30 batches of naturally cultured C. sinensis and 4 kinds of counterfeits extracted by methanol and water were analyzed using NMR technology. 9 characteristic peaks were defined as quantitative criterion after comparison, and NMR fingerprints of C. sinensis were established. According to the result it is highly similar between naturally cultured C. sinensis and wild ones by comparing their NMR fingerprints. However, NMR spectra of four kinds of adulterants showed differences with C. sinensis. The result also showed that NMR fingerprint of C. sinensis are highly characteristic and specific. The NMR characteristic fingerprint of wild C. sinensis was consistent with the naturally cultured C. sinensis, and it indicated that the chemical constituents of wild C. sinensis and naturally cultured C. sinensis are nearly the same.
