Abstract | ||||
From the flowers of A. saligna a new flavanone glycoside ( naringenin 7-O-B-D-glucoside 6''-acetate) was isolated, besides three known flavanones (naringenin, naringenin 7-O-B-D-glucoside and 6-C-glucosylnaringenin); Two flavonols (quercetin and quercitrin); B-sitosterol and B-sitosterol-O-glucoside. Their structures were determined based on their spectral data (IR, UV, EI MS, FAB MS, 1H- and 13C NMR). Assignments of the 13C NMR were confirmed by 2D NMR experiments and addressed herein for the first time for some of these compounds. | ||||
