The present pandemic disease COVID-19 demands an urgent need for more efficient antiviral drugs against SARS-CoV-2. 22-Hydroxyhopane is a bioactive triterpenoid compound with antibacterial activity, present in the leaves of  Adiantum latifolium . In this study, molecular docking method revealed strong binding affinity of the compound for ten proteins essential for SARS-CoV-2 multiplication in host cells, including seven nonstructural proteins, two structural proteins and one receptor protein, with a binding energy of −7.61 to −9.82 kcal/mol and inhibition constant &lt;1 μM. MDS and MM-PBSA analysis of the best ranked complex further confirmed the results. The targets selected include six enzymes, RNA binding protein, spike protein, membrane protein and ACE2 receptor of SARS-CoV-2. It is the first report of a natural compound from  A. latifolium  having multitargeted activity against SARS-CoV-2. We conclude that 22-hydroxyhopane may be used as a best source for the development of novel therapeutic drugs for COVID-19, but requires further evaluations.
