Abstract Three new lignans, kadsulignans L-N, were isolated from the seeds of Kadsuracoccinea , of which kadsulignan M shows anti-HIV activity in vitro . Their structures, including absolute configurations, were elucidated by spectroscopic analysis and chemical conversions. In addition, their atropisomerization and CD rule for assignment of biphenyl configuration were also discussed and the biphenyl
