Three new lignans 14-O-demethyl polysperlignan D (1), kadsurindutin E (16), coccilignan A (17), and fifteen known lignan compounds (2–15 and 18) were isolated from the roots of Kadsura coccinea. Their structures were elucidated on the basis of detailed spectroscopic analyses (IR, ESIMS, HR-ESIMS, 1D and 2D NMR, and CD). The NO production inhibitory activities of these isolated lignans were also evaluated.
