摘要
This work reports the isolation and characterization of twelve compounds, including six coumarins and two flavonoids from the ethyl acetate extract of the flowers of Edgeworthia gardneri. Their structures were elucidated on the basis of various spectroscopic methods (UV, IR, 1H and 13C NMR) and identified as umbelliferone (1), edgeworin (2), edgeworthin (3), daphnoretin (4), rutamontine (5), edgeworoside A (6), 7-Hydroxy-4'-methoxyflavone (7), kaempferol-3-O-beta-D-(6 ''-E-p-coumaroyl)-glucopyranoside (8), pentadecanoic acid (9), beta-sitosterol (10), beta-adenosine (11), beta-daucosterol (12). The chemotaxonomic significance of these compounds was summarized. (C) 2012 Elsevier Ltd. All rights reserved.
