Abstract
Objective: To establish the quality standard for Penyankang Suppository. Method: Thin Layer Identification (TLC) was used for the qualitative identification of Caulis Sargentodoxae, Radix Salviae Miltiorrhizae, Rhizoma Corydalis and Rhizom Sparganii. High performance liquid chromatography (HPLC) was used to determine the contents of salvianolic acid B and tetrahydropalmatine. Results: Thin Layer Identification (TLC) spots were clear and well separated without interference in the negative reference. The compounds showed a good linearity in a determination range. Conclusion: The method is simple, reliable and accurate with good precision. It can be used for the quality control of Penyankang Suppository.
