| Abstract: | The chemosynthesis process of roxatidine acetate was tracked and monitored by TLC.The developer was methanol∶chloroform∶ammonia water as 1∶4∶0.5（V/V/V）in the step 1—3.When the developer was petroleum ether∶chloroform：acetone∶ethanol as 23.5∶12∶2∶2.5（V/V/V/V） in the step 4,Rf of the intermediates and the end products can be controlled between 0.25 and 0.60,objects can be well separated on silica gel plate.The Rf of roxatidine acetate was 0.42.It can be regarded as a main detection method for quickly tracing the chemosynthesis process. |
