Objective To establish a method for quality control of Jiangya Yishen Granula. Methods Spanishneedles Herb, Radix Polygoni Multiflori, Fruetus Corni, Radix Scrophulariae, Rhizoma Alismatis and Radix Cyathula were identified by TLC. A method of HPLC to determine 2,3,5,4’-tetrahydroxystilbene-2-0-?-D-glucosid, the main effective component from Radix Polygoni Multiflori, was developed. Results The studies on the quality control showed that the characteristics for identification by TLC were distinct. The quantification method had the linear range of 0.016 3～0.522 ?g (r=0.999 9). The average recovery rate was 99.7%, and its RSD was 0.51%. Conclusion The methods can be used for the quality control of the preparation.
