Before revision:  Considering the published literatures on medicinal importance, total 154 phytochemicals with analogous structure from limonoids and triterpenoids were selected to search potential inhibitors for the five  protein targets of SARS-CoV-2, i.e., 3CLpro (main protease), PLpro ( papain like protease), SGp-RBD (spike glycoprotein-receptor binding domain), RdRp (RNA dependent RNA polymerase , ACE2 ( angiotensin converting enzyme 2).
