A dihydrochalcone from Lindera lucida

Abstract A new dihydrochalcone, 3′,5′-dihydroxy-2′,4′,6′-trimethoxydihydrochalcone and five known compounds, methyl linderone, 5-hydroxy-6,7,8-trimethoxyflavone (alnetin), 2′-hydroxy-3′,4′,5′,6′-tetramethoxydihydrochalcone (dihydrokanakugiol), 2′-hydroxy-3′,4′,5′,6′-tetramethoxychalcone (kanakugiol) and 2′,3′,4′,5′,6′-pentamethoxychalcone (pedicellin) were isolated from twigs of Lindera lucida . The structures of these compounds were determined by spectral analyses and chemical correlations.
