Abstract
Five new dibenzocyclooctane lignans, schisanwilsonins K–O
(1–5), together with eighteen known lignans
(6–23) were isolated from the stems of Schisandra
wilsoniana. The structures of these new compounds were elucidated by
spectroscopic methods, including 2D-NMR techniques. Several compounds were
found to show anti-HIV and anti-HBV activity.
