Adenosine

Adenosine levels in C. militaris have been quantified at 0.18% in fruiting body and 0.06% in mycelium (Huang et al., 2009, Journal of Analytical Methods in Chemistry). The physiological effects of adenosine receptor signaling are extensively documented in cardiovascular pharmacology (Jacobson & Gao, 2006, Nature Reviews Drug Discovery). In the context of Cordyceps supplementation, adenosine is believed to contribute to smooth muscle relaxation and improved tissue oxygenation, though direct clinical evidence attributing athletic performance effects specifically to adenosine (vs. cordycepin) is limited.

Adenosine is a well-characterized bioactive compound present in multiple Cordyceps species. Its content in C. guangdongensis contributes to the species' overall pharmacological profile, particularly immunomodulatory and anti-tumor activities noted in Cordyceps genus reviews. Adenosine content is used as a quality marker for Cordyceps products in the Chinese Pharmacopoeia.
