Phytochemical investigation of branch wood of Pinus banksiana Lambert resulted in the isolation of a new lignan glycoside, which was named phillyrin-6″-α-rhamnoside. The structure of the new compound was mainly elucidated by chemical and spectral evidence including 2D nuclear magnetic resonance studies. In addition, four known phenolics, including a phenylpropanoid glucoside (trans-isoconiferin), a phenolic acid (caffeic acid), a neolignan (cedrusin), and a lignan glucoside (phillyrin), were reported for the first time to be present in P. banksiana.
