Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has caused Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic. Flavonoids derived Chinese patent medicines has outstanding curative effects for the improvement and treatment of COVID-19. There are numerous studies suggesting that flavonoids-rich tea have antiviral effects. However, bioactive compounds from tea flavonoids with anti-COVID-19 effect, and the potential molecular mechanisms are unclear. In this study, we performed a molecular docking of 468 tea flavonoids and its derivatives with main protease (Mpro), angiotensin-converting enzyme 2 (ACE2), RNA dependent RNA polymerase (RdRp), compared with the positive control drugs of each target. The results suggested that ACE2 and RdRp are the main targets inhibited by tea flavonoids.Q3G Isovitexin, and TF would be considered as the potential candidate compounds of RdRp and ACE2. Our study provides a theoretical basis for further drug design of anti-COVID-19.
