从野生睡莲（Nymphaea lotus L.）中分离得到3个新的黄酮醇，杨梅素-3′- o -（6′-对香豆醇基）葡萄糖苷和2个外旋大环衍生物，以及已知的杨梅素-3- o -鼠李糖苷和五烯丙基葡萄糖。这是第一份来自任何来源的关于这种宏观周期的报告。(C) 2003, Elsevier Ltd.出版
Three novel flavonols, myricetin-3'-O-(6"-p-coumaroyl)glucoside and two epimeric macrocyclic derivatives, as well as the known myricetin-3-O-rhamnoside and pentagalloyl glucose, have been isolated from the wild water lily Nymphaea lotus L. and identified using 2D NMR. This is the first report of such a macrocycle from any source. (C) 2003 Published by Elsevier Ltd.
