Abstract:
OBJECTIVE: To prepare Tongmailing Granules and establish a quality standard thereof. METHODS: To prepare Tongmailing Granules by reflux extraction, identify the nature of Fructus Crataegi and Radix Puerariae in the granules by TLC, and determine the content of Ursolic Acid through thin layer scanning. RESULTS: TLC identification of Fructus Crataegi and Radix Puerariae is a highly specific approach. Ursolic Acid had a linear calibration curve ranging 0. 990～ 4. 950? g? mL-1 ( r=0. 999 8) , with recovery rate reaching 99. 91% ( RSD=2. 3% ) . CONCLUSION: This preparation technique is workable, and reliable in quality control.
