Abstract Four new lignans, (7′ R ,8′ S )-4,4'-Dimethoxy-strebluslignanol ( 1 ), 3'-Hydroxy-isostrebluslignaldehyde ( 2 ), 3,3'-Methylene-bis(4-hydroxybenzaldehyde) ( 3 ), and 4-Methoxy-isomagnaldehyde ( 4 ), and six known lignans ( 5 – 10) , were isolated from the roots of Streblus asper . The structures of these molecules were elucidated through various spectroscopic methods of analysis, including 1D and 2D NMR. The stereochemistry at the chiral centres was determined using the CD spectrum and… Expand
