ABSTRACT
Objective To investigate the kinetics of absorbing timosaponin by AB-8 resin.Methods Static absorption experiment,dynamic absorption experiment and series dynamic absorption experiment were carried out,and then the content of timosaponin was detected by spectrophotometry.Finally,the static absorption curve and the dynamic absorption curve were figured out.Results The result of static absorption experiment showed that the parameters of Lagergren equation are Kad=0.0186,r=0.9986,and the parameters of Dumwals-Wagner are K=0.0081,r=0.9958.In dynamic absorption experiment,the leaking of timosaponin is found and the penetrating point is at 600mL(0.1g/mL).Conclusion The mechanism of AB-8 resin absorbing timosaponin is characterized as liquid membrane diffusion at the early phase and intragranular diffusion at the later phase.Leaking phenomena in dynamic absorption experiment can be solved by three tubes in series.Therefore,this method can be used for the research of Chinese herbal medicine.
