[The lignins from Torreya grandis cv. Merrilli].
OBJECTIVE
To separate and identify the chemical constituents of the aril of Torreya grandis cv. Merrilli.


METHODS
Three lignins were isolated by chromatography and their chemical structures were elucidated by IR, EI-MS, 1HNMR, 13CNMR, DEPT and 2D-NMR spectral methods.


RESULTS
Three lignins were identified as pinonesinol, dihydrodehydrodiconiferylalcohol and (7,8-cis-8,8'-trans)-2',4'dihydroxyl-3, 5-dimethoxy-lariciresinol.


CONCLUSIONS
These compounds were isolated from this plant for the first time, and compound III is a new compound.
