Abstract

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.

Description

technical field [0001] The present invention relates to the field of natural medicinal chemistry and medical technology, in particular to isoflavone compounds tectoridin, iridin, irisflorentin, Use of tectorigenin and irigenin in the preparation of medicines or health food for the prevention and treatment of hepatitis. Background technique [0002] Shegan is the dry rhizome of Belamcanda chinensis (L.) DC. Bitter and cold in taste, enters the liver and lung meridians, has the effects of clearing away heat and detoxification, relieving sore throat and eliminating phlegm, dispersing blood and reducing swelling, and mainly treating sore throat, phlegm, cough and asthma. It is a commonly used Chinese herbal medicine and is rich in resources. Studies have shown that Shegan is rich in isoflavones, which is one of its characteristic components. The main components that have been reported to be contained in Shegan are irisgenin, irisaxanthin, hypoirisin, irisoflavone neoaglycone ...
