A novel coronavirus disease (COVID-19), caused by SARS-CoV-2, has spread over more than 100 countries all over the world. The World Health Organization has recognized Coronavirus as a pandemic and finding an effective drug for this infectious disease is of high importance. In this study, we have explored the potent inhibitors of COVID-19 main protease from Tinospora cordifolia an Ayurvedic herb locally called as Amrita meaning ‘immortality’ and two other Ayurveda plants namely Cinnamomum zeylanicum and Myristica fragrans. Saponarin, a phytochemical present in Tinospora cordifolia showed a very promising result with the binding affinity of − 8.75 kcal/mol. Remdesivir and Favipiravir, the experimental drugs that are known to show inhibitory activity towards COVID-19 are used as a control. The Docking results were verified by the means of molecular dynamic analysis. This study suggests that Saponarin can be a potential inhibitor for the main protease of the COVID-19.
