Effect of Irradiant Sterilization on Quality of American Ginseng Cataplasm

Abstract:

Objective: To investigate the influence on the adhesive activity and effective component content in American ginseng cataplasm with different radiation doses. Method: A HPLC method was established for the determination of 3 kinds of ginsenoside in American ginseng cataplasm; changes of adhesive activity and main constituents were compared in samples irradiated with different radiation doses. Result: ⁶⁰Co-γ radiation with different radiation didn't lead the adhesive activity of American ginseng Cataplasm to change obviously, and the content of ginsenoside Rg₁, ginsenoside Re and ginsenoside Rb₁ in American ginseng cataplasm was about 8, 90,90,22 and 189 μg·cm^-2 respectively before and after ⁶⁰Co-γ radiation. Conclusion: There is no obvious influence on the adhesive activity and the content of main constituents of American ginseng cataplasm before and after sterilization with the method of ⁶⁰Co-γ radiation.
