摘要：Two flavonoids 3'-formyl-4',6'-dihydroxy-2'-methoxy-5-methylchalcone and (2S)-8-formyl-5-hydroxy-7-methoxy-6-methyl- flavanone together with five known compounds, were isolated from the dried buds of Cleistocalyx operculatus. Their structures were determined on the basis of spectroscopic analyses (UV, IR, EIMS, H-1, C-13 NMR and HMBC). (C) 2003 Elsevier Ltd. All rights reserved.
