A new bidihydroflavonoid, thuidinin 1 , together with 5 known compounds including one known biflavonoid 3′,3′′′‐binaringenin ( 2 ) and four other known natural products pentadecane ( 3 ), methyl β ‐orcinolarboxylate ( 4 ), β ‐sitosterol ( 5 ) and daucostenol ( 6 ), were isolated from leaves of Thuidium kanedae Sak. Their structures were established on the basis of 1D and 2D spectroscopic analysis. The absolute stereochemistry of compounds 1 and 2 was determined by CD spectra.
