Title: Catalpol Content Changes in Rehmannia Glutinosa Libosch under Certain Conditions
Abstract: Objective: To determine the change of pH and the contents of catalpol during the process and the simulated process of Rehmannia glutinosa libosch. Methods: Use pH-meter to determine the density of H+ and use HPLC to determine the contents of catalpol. Results: The density of H+had been demonstrated that it had a decreased tendency during the process and simulated process. The contents of catalpol were different under different processes,and were decreased obviously at the initial stage under simulated process. Conclusion: The caryotheca and tonoplast in cell may rhegmaed under process,accordingly,glucosidase meets catalpol and makes it degradated,it is obvious that the glucosidase is more active at low temperature from the reseach in simulated process of Rehmannia glutinosa libosch,while the H+may has an effect on the degradation of catalpol at the later stage of process.
