ABSTRACT

Objective: To establish quality standard on Qinggan Granules (Radix Actinidiae valvatas, Radix Scutellariae, Rhizoma Atractylodis Macrocephalae, Badix Bupleuri, etc.). Methods: Radix Actinidiae valvatae, Radix Scutellariae, Rhizoma Atractylodis Macrocephalae and Radix Bupleuri were identified by TLC, and the content of Baicalin was determined by dual wavelength TLC scanning. Results: Baicalin showed a linear relationship at the range of 0.55～4.4?g, the average recovery was 102.9%. Conclusion: Method is simple, quick and good reproducible.
