摘要：

The novel flavonol, myricetin 3-O-alpha-rhamnopyranosyl 1 --> 6)beta-galactopyranoside was isolated from leaves of the water lily Nymphaea x marliacea (white petals), while four flavonols, quercetin and the 3'-xylosides of myricetin, quercetin and quercetin 3-methyl ether were isolated from red petals of the variety Escarboucle. Their structures were elucidated by homo- and heteronuclear two-dimensional NMR techniques, other spectroscopic techniques and chromatography. This is the first report of flavonol 3'-xylosides as flower pigments. (C) 1998 Elsevier Science Ltd. All rights reserved.
