目前冬虫夏草市场伪品泛滥，鉴别困难。本文采用核磁共振技术对3个不同产地的21批野生冬虫夏草、30批冬虫夏草野生抚育品和4种冬虫夏草伪品的水提物及醇提物进行了测定，比较分析之后确定了9组特征峰作为量化标准，建立了冬虫夏草的核磁特征指纹图谱。对野生冬虫夏草、冬虫夏草野生抚育品和冬虫夏草伪品的核磁特征指纹图谱进行比较分析发现，野生冬虫夏草和冬虫夏草野生抚育品具有高度的相似性，4种冬虫夏草伪品的核磁特征图谱与野生冬虫夏草及冬虫夏草野生抚育品的核磁指纹图谱均存在不同程度的差异。比对结果也显示，冬虫夏草的核磁指纹图谱具有很强的特征性和专属性。野生冬虫夏草与冬虫夏草野生抚育品核磁指纹图谱具有良好的一致性，表明两种冬虫夏草的化学成分基本相同。

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.
