Dibenzocyclooctane lignans from the stems of schisandra wilsoniana

摘要

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.
