Аннотация:
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. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
