Abstract:
The five new lignans designated 3′,4′‐de‐ O ‐methylenehinokinin ( 1 ), taiwaninolide ( 2 ), 8′‐hydroxysavinin ( 3 ), isoguamarol ( 4 ), and 4′‐ O ‐methylsalicifolin ( 5 ), as well as the new 4‐(3,4‐dimethoxybenzyl)dihydro‐3‐(4‐hydroxybenzyl)furan‐2(3 H )‐one ( 6 ) were isolated from the roots of Taiwania cryptomerioides , besides the three known compounds hinokinin ( 8 ), savinin ( 9 ), and 3,4‐de‐ O ‐methylenehinokinin ( 7 ). The structures of the new constituents were elucidated through chemical and spectral studies. A compound previously isolated from the heartwood of Chamaecyparis obtusa var. formosana was assigned structure 1 ; however, this structure has now been revised to be 3,4‐de‐ O ‐methylenehinokinin ( 7 ).
