从白花瓣睡莲（Nymphaea x marliacea）叶片中分离到新型黄酮醇杨梅素3- o - α -rhamnopyranosyl 1—bbbb6) β -半乳糖吡喃苷，从红花瓣中分离到4种黄酮醇、槲皮素以及杨梅素、槲皮素和槲皮素3-甲基醚的3′-木糖苷。它们的结构通过同核和异核二维核磁共振技术、其他光谱技术和色谱法进行了鉴定。这是首次报道黄酮醇3′-木糖苷作为花色素。1998爱思唯尔科学有限公司版权所有。
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.
