In this study, chemical investigation of methanol extract of the air-dried fruits of Luffa cylindrica led to the identification of a new delta-valerolactone (1), along with sixteen known compounds (2-17). Their chemical structures including the absolute configuration were elucidated by extensive spectroscopic analysis and electronic circular dichroism analysis, as well as by comparison with those reported in the literature. For the first time in literature, we have examined the binding potential of the isolated compounds to highly conserved protein, M(pro) of SARS-CoV-2 using the molecular docking technique. We found that the isolated saponins (14-17) bind to the substrate-binding pocket of SARS-CoV-2 M(pro) with docking energy scores of -7.13, -7.29, -7.47, and -7.54 kcal.mol(-1), respectively, along with binding abilities equivalent to an already claimed N3 protease inhibitor (-7.51 kcal.mol(-1)).
