摘要:
Three new dibenzocyclooctane-type lignans, kadsutherins A-C (1-3), were isolated from the stems of two Kadsura species. Their structures and configurations were elucidated by spectroscopic methods including 2D-NMR and HR-MS techniques. Kadsutherin C (3) is the first dibenzocyclooctane lignan without an oxygen-containing substituent at C(2).
