We would like to introduce our research on coronavirus: “Meta-analysis of flavonoids with antiviral potential against coronavirus”. We analysed data that contains information about crucial metabolites neutralising coronavirus: rhoifolin, pectolinarin, herbacetin. In this publication we focus on the best source of those metabolites. This problem was not considered in literature so far and it may be helpful in drug development against SARS-CoV-2. This is our contribution into the fight against SARS-CoV-2, so please respect our copyright and cite our work as: Sawikowska A. (2020): Meta-analysis of flavonoids with antiviral potential against coronavirus. Biometrical Letters. DOI: 10.2478/bile-2020-0002.
