New lignans and a phenylpropanoid from Triadica rotundifolia and their antineuroinflammatory and antioxidant activities

Three new compounds (1‒3), including a phenylpropanoid (1), a bistetrahydrofuran lignin (2), and a lignan dimer (3), and seven known lignans (4‒10), were isolated from an EtOH extract of the aerial parts of Triadica rotundifolia. The structures of the new compounds were elucidated by comprehensive spectroscopic analyses. New compounds 1−3 were evaluated for their antineuroinflammatory and antioxidant activities. Research on the...
