Random amplified polymorphic DNA (RAPD) and high performance liquid chromatography (HPLC) were applied to investigate genetic and chemical variations of 2 natural C sinensis, 16 fungal strains isolated from C. sinensis, and 2 fungal strains of C. militaris. Five of the 68 arbitrary decamer primers were available for discrimination of the investigated samples. As a result, 20 investigated samples were divided into three main clusters according to the genetic distance, and some fungal strains isolated from natural C sinensis were obviously different. But according to the contents of nucleosides, including uracil, uridine, hypoxanthine, inosine, guanosine, adenosine, adenine, and cordycepin, natural and cultured Cordyceps were in two individual sub-groups, which suggested that chemical characteristics among cultured mycelia of different fungal strains isolated from natural C sinensis were similar, but they were different from natural one.
