Objective: To investigate in vitro release law and mucosal permeability mechanism of linarin in Chrysanthemi Indici Flos total flavonoids bioadhesive bilayer sustained-release patches. Method: Taking linarin as index components
in vitro release law of total flavonoids bioadhesive bilayer sustained-release patches was investigated;abdominal skin of bullfrog was adopted
mucosal permeability mechanism of this preparation was explored through transdermal diffusion test. Result: Equations of in vitro release and transdermal diffusion were fitted lnQ=1.387lnt-0.461(r=0.990) and lnQ=0.969lnt+3.240(r=0.994 3)
which were in line with Ritger-Peppas equation.Release system of this preparation in release medium was synergy results of Fick diffusion and gel matrix erosion. Conclusion: These prepared patches have good sustained-release and a certain mucosal permeability.
