Two new lignans, named as 6-hydroxyhinokinin and 6-hydroxyhinokinin-6-O-β-D-glucopyranoside, together with five known compounds: elemol, oplodiol, catechin, β-sitosterol and daucosterol were isolated from Kadsura heteroclita. The structures of these compounds were characterized by extensive 1D and 2D NMR spectral experiments, chemical analysis and comparison with literature data. The absolute structures of the novel lignans were elucidated as 8S, 8′S, based on their optical rotations.
