ABSTRACT
Objective:
A study was conducted to clarify the anti-influenza virus effect of agricultural, forest and fishery products in Ishikawa Prefecture.Method:
The samples were prepared by both hot-water and ethanol extraction. The Madin-Darby canine kidney (MDCK) cells infected with PR8 strain were cultured in Dulbecco's Modified Eagle Medium(DMEM) containing extract for 24 hours and measured virus titer of supernatants by focus-forming reduction assay. Time-of-addition assay was performed to determine the inhibition stage in virus proliferation by the extract. The active ingredients were purified using a solid-phase extraction column (silica gel base C18).Results:
We revealed that many products have anti-influenza virus activity. Especially, four products ( Matteuccia struthiopteris, Colocasia esculenta, Sagittaria trifolia, and Eleucine coracana) show strong activity and inhibit several stages in virus proliferation.Conclusion:
We performed screening to 46 agricultural, forest and fishery products and found the four products ( Matteuccia struthiopteris, Colocasia esculenta, Sagittaria trifolia, and Eleusine coracana) inhibit virus proliferation strongly. In addition, the isolation and identification of the active ingredients contained in these remain as a future study.
