RESUMEN
In this study, 10 samples of parasites, cursive, and the whole from six different species of Cordyceps were determined and compared by HPLC and LC-MS methods. Uridine, adenosine, and cordycepin were selected as the main evaluation index. The anti-fibrotic activity of different species Cordyceps extracts was observed using in vitro TGF-β1-induced ECM accumulation in human embryonic fibroblasts CCC-ESF-1. The results demonstrated that the number of atoms and hyphae ingredients of different species showed little difference, however, the content distribution of each component has obvious significance. The in vitro anti-fibrotic activities of different species were as follow： Cordyceps flower > Cicada Cordyceps (Cicada flower)> Silkworm Cordyceps> Tussah Cordyceps>natural Cordyceps. Our preliminary data could serve as reference for the discovery of artificial alternatives of natural Cordyceps.
