抄録

Four new lignans, 3′,4′-O,O-demethylenehinokinin (1), chamalignolide (2), 8′β-hydroxyhinokinin (3) and 7β,8β-epoxyzuonin A (4), as well as (−)-hinokinin (5), and (−)-zuonin A (6), were isolated from the heartwood of Chamaecyparis obtusa var. formosana. The structures of these lignans were unambiguously determined by spectroscopic methods. And the absolute configuration of 1 was elucidated with a circular dichroism (CD) spectrum.
