Six new polyoxygenated terpenoids, podovirosanes A-F ( 1 - 6 ), and two known polyketides ( 7 and 8 ) were isolated from the roots of F. virosa . Their structures, along with absolute configurations, were deduced using spectroscopic analysis as well as computational calculations, including TDDFT calculation of ECD spectra and GIAO NMR calculations combined with DP4+ probability analysis. Compounds 2 , 3 , 5 , and 8 were found to reduce the phosphorylation levels of NF- κ B p65 in SARS-CoV-2 pseudovirus-stimulated PMA-differentiated THP-1 cells.
