• 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.
