Norlignan from the knot resin of Araucaria angustifolia

Phytochemistry, 1992
Abstract A new norlignan, 2,3-bis-( p -hydroxyphenyl)-2-cyclopentene-1-one, was isolated from the knot resin powder of Araucaria angustifolia . The structure was elucidated by spectroscopic chemical analyses. In addition 4,4′- dihydroxychalcone, cryptoresinol (norlignan), four known lignans and one known norlignan, were isolated for the first time ...
