| Abstract: | AbstractA new dihydrochalcone, namely 2',5'-dimethyl-3'-methoxy-4',6'-dihydroxyl-dihydrochalcone (1) together with five known compounds were isolated from the CHCl3 extract from Empetrum nigrum L. var. japonicum K. Koch (E. nigrum). The structures of 1 was elucidated by spectroscopic methods, including UV, IR, HR-ESI-MS and extensive 1D and 2D NMR techniques. |
