Abstract

The invention discloses a method for discriminating cordyceps sinensis storage time. The method comprises the following steps of extracting cordyceps sinensis powder by an organic solution, carrying out filtration or centrifugation, then carrying out condensation, carrying out thin layer chromatography on the solution and an ergosterol contrast, taking out a thin layer plate, carrying out heating and carrying out inspection and determination under the action of a ultraviolet light lamp. Through positions and brightness comparison of spots of a sample on the thin layer plate, substantial acquisition year of cordyceps sinensis can be known. The method has simple experiment processes, is free of an expensive detection apparatus and has a practical value in cordyceps sinensis market transaction.
