To investigate whether there are differences in the medicinal components of P. ternata in these two lines, the contents of proteins, polysaccharides, alkaloids and nucleosides in tubers of P. ternata were determined. The content of polysaccharide was measured by the optimized phenolic phenol method, protein content was obtained by ultraviolet spectrophotometry, and guanosine, adenosine and ephedrine in P. ternata were measured by high performance liquid chromatography (HPLC).
