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