Problems solved by technology

[0003] The drugs currently used for treatment are mainly interferon and lamivudine nucleoside analogues, but the results of the treatment are not so ideal. In addition to the side effects of interferon, it only has a therapeutic effect on patients with specific symptoms; As a reverse transcriptase inhibitor, although it can effectively inhibit the replication of hepatitis B virus, as the course of treatment progresses, resistant mutant virus strains will appear and lead to recurrence of hepatitis
Although some new nucleoside analogs such as adefovir have shown good anti-hepatitis B virus effects, as the course of treatment progresses, drug-resistant mutant viruses will still appear and lead to recurrence of hepatitis

Embodiment Construction

[0015] The natural extract for inhibiting hepatitis B virus and its main active ingredient provided by the invention are the natural extract extracted from green tea. Wherein: the main component of the extract is tea polyphenol; the main component of the tea polyphenol is EGCG, namely epigallocatechin gallate.

[0016] When the tea polyphenols in the above natural extracts are applied at a concentration of 10-40 mg / ml, they can effectively inhibit the expression of antigenic proteins, DNA replication, the formation of replication intermediates and the formation of covalently closed DNA of hepatitis B virus.

[0017] The above-mentioned active ingredient EGCG, when its monomer concentration is 6.25-50 μM, can effectively inhibit the expression of antigen protein, DNA replication, the formation of replication intermediates and the formation of covalently closed DNA of hepatitis B virus.

[0018] The invention provides the natural extract for inhibiting hepatitis B virus and its ...
