Two new lignans were isolated from Saururus chinensis, along with eight known compounds. Their structures were elucid ated on the basis of spectroscopic and physico-chemical analyses.All the isolates were evaluated for in vitro inhibitory activity against DGAT1 and DGAT2.Amongthem, compounds 2, 3, 5 and 7 were found to exhibit selective inhibitory activity on DGAT1 with IC50 valuesranging from 44.3 ± 1.5 to87.5± 1.3 μM.
