| Objective: The sustained-release tablets of Panax notoginseng were studied, and through this study, the quality content standard for some tablets were determined. Contents: Studies on the preparation, analysis method assessment of Panax notoginseng sustained-release tablets and Paris Polyphylla saponin dispersible tablets, hydrolysis of Panax notoginseng, Methods: 1. The Panax notoginseng sustained-release tablets were prepared by solvent method, and compared the different influence of different subsidiary materials and stuff ,and defined the optimum component. 2. Panax notoginseng were hydrolyzed ,the structures were identified on the basis of spectral data. 3. The quality control of Panax notoginseng sustained-release tablets and Paris Polyphylla saponin dispersible tablets were examined by HPLC. Results: 1. The Panax notoginseng sustained-release tablets were successful prepared. 2.. The quality standard of Panax notoginseng sustained-release tablets and Paris Polyphylla saponin dispersible tablets were different established. 3.. The hydrolysis test of Panax notoginseng were obtained five compounds. Conclusions: The purpose of sustained-release Panax notoginseng main composition were achieved by form of a drug change, the component for Panax notoginseng sustained-release tablets is optimum and feasible by assessment quota. The quality standard of Panax notoginseng sustained-release tablets and Paris Polyphylla saponin dispersible tablets were different established.
