Methods: Taking Monoammonium Glycyrrhizinate as index， we used the technique of HPLC to determine its content. Then compared the difference among water-decocting water-extracting and alcohol-depositing; % ammonia-extracting and 70% alcohol ultrasonic-method. Results: The content from % ammonia-extracting extraction of Monoammonium Glycyrrhizinate was the higher. In the range of μg， the Monoammonium Glycyrrhizinate showed good linear relatiohip. The recovery of Monoammonium Glycyrrhizinate was %. Conclusion: The content from % ammonia-extracting extraction of Monoammonium Glycyrrhizinate is the higher. The trafer rate of Monoammonium Glycyrrhizinate is the highest. The % ammonia-extracting is reasonable， feasible and efficient.
