Summary: | A new dihydrochalcone, 2',4'-dimethoxydihydrochalcone ( 1 ), together with 7 known compounds, 2',4'-dihydroxydihydrochalcone ( 2 ), 2'-hydroxy-4'-methoxydihydrochalcone ( 3 ), 2'-hydroxy-4'-methoxychalcone ( 4 ), 1-(3,5-dihydroxy-4-methoxyphenyl)-2-(3-hydroxyphenyl) ethane ( 5 ), 2,3,4,7-tetramethoxy-9,10-dihydrophenanthrene ( 6 ), 5-hydroxy-2,3,4-trimethoxy-9,10-dihydrophenanthrene ( 7 ) and 5,7-dihydroxy-6,8-dimethyl flavanone ( 8 ) were isolated from the shoots of Empetrum nigrum L. The structures of these compounds were elucidated using 1D and 2D NMR experiments along with HR-ESI-MS. Compound 6 is reported for the genus Empetrum for the first time. |
