The invention relates to an application of isoflavonoids compounds, i.e., tectoridin, iridin, irisflorentin,
tectorigenin or irigenin, separated from the
belamcanda chinensis of an iridaceae belamcanda
plant to preparation of drugs or health-care foods for preventing and treating
hepatitis, relating to the technical field of natural pharmaceutical
chemistry and medicines. In the invention,
HBsAg (
Hepatitis B Surface
Antigen) and
HBeAg(
Hepatitis B e
Antigen) resistance experiments are carried out by adopting detection reagents of an
HBsAg diagnostic reagent kit and an
HBeAg diagnostic reagent kit; and an experimental result discovers that all the tectoridin, the iridin, the irisflorentin, the
tectorigenin and the irigenin have an obvious
hepatitis B
virus resistant action, thus the tectoridin, the iridin, the irisflorentin, the
tectorigenin and the irigenin can be used for preparing the drugs or health-care foods for preventing and treating
hepatitis viruses.
