To respond to the public panic, government and private research organizations of every country keep working on the COVID-19 pandemic, even though still there is a lack of more efficacious medicine for the choice of Coronavirus disease treatment To counteract on this situation several approved drugs including anti-malarial (hydroxychloroquine and chloroquine), and few anti-viral (remdesvir) agents are choice of treatment for COVID-19 However, these agents suffer from certain limitation in their uses and pointed that there is no specific treatment or vaccine available to counter this contagious disease Hence, there is urgent requirement to find a specific cure for the disease In this view, there are several ongoing clinical trials of both western and traditional medicines In present study, phytochemicals from Camellia sinensis were retrieved from the database and identified based on their ability to inhibit matrix metalloproteinase (MMPs) against SARS-CoV-2 main protease Camellia sinensis entails of a massive number of phytochemicals with a good source of polyphenols such as Catechin, Epicatechin, Epigallocatechin and (–)-Epigallocatechin gallate Molecular docking was performed using the GLIDE docking module of Schrodinger Suite software The analysis displayed docking score for the five polyphenols i e theaflavin (− 8 701), 1-O-caffeoylquinic acid (− 7 795), Genistein (− 7 168), Epigallocatechin 3-gallate (− 6 282) and Ethyl trans-caffeate (− 5 356) Interestingly, theaflavin and Epigallocatechin 3-gallate have not revealed any side effects These polyphenolic compounds had a strong binding affinity with hydrogen bonds and a good drug-likeness score Therefore, Camellia sinensis could be the beneficial option in the prophylaxis of the COVID-19 outbreak
