Abstract

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).

Three new cyclolanostane triterpenoids, 1 -3, were isolated from the EtOH extract of the stems of Kadsura heteroclita. Their structures and configurations were determined by extensive 1D-and 2D-NMR spectroscopy, high-resolution mass spectrometry (HR-MS), and circular dichroism (CD) spectroscopy. The
