Natural Cordyceps sinensis, which is a valuable anti-tumor, immunomodulatory, and antiviral agent in Asia, has been overexploited in recent years. Therefore, it is important for cultivated C. sinensis to be recognized in the market. In this research, the main components of entirely cultivated, naturally grown C. sinensis, and stiff worms across different sampling years were detected and compared by HPLC-MS and UV spectrometry. The results indicated that the mean levels of adenosine and cordycepin were significantly higher, whereas the mean levels of mannitol and polysaccharides were remarkably lower in the cultivated type than in the natural type. No distinct difference in the average soluble protein content was observed. The composition of the stiff worms was similar to that of the natural herb, except that the total soluble protein content was higher, and that of mannitol was lower. In addition, the ultraviolet absorption spectroscopy of the three types showed high similarity at 260 nm. This research indicates that the main nutritional composition of cultivated and natural C. sinensis is identical and that cultivated type can be used as an effective substitute.
天然冬虫夏草在亚洲是一种有价值的抗肿瘤、免疫调节和抗病毒药物，但近年来已被过度开采。因此，在市场上识别栽培的冬虫夏草非常重要。在这项研究中，通过高效液相色谱-质谱联用（HPLC-MS）和紫外分光光度法检测和比较了不同年份完全栽培、天然生长的冬虫夏草和僵蚕的主要成分。结果表明，与天然型相比，栽培型的腺苷和蛹虫草素含量明显较高，而甘露醇和多糖含量明显较低。可溶性蛋白含量无明显差异。僵蚕的成分与天然药材相似，只是总可溶性蛋白含量较高，甘露醇含量较低。此外，三种类型的紫外吸收光谱在 260nm 处具有很高的相似度。本研究表明，栽培和天然冬虫夏草的主要营养成分相同，栽培型可作为有效替代品。
