  Euodionosides A–G: Megastigmane glucosides from leaves of Euodia meliaefolia

  摘要：

  From a 1-BuOH-soluble fraction of the MeOH extract of leaves of Euodia metiaefolia, collected in Okinawa, seven megastigmane glucosides, named euodionosides A-G, were isolated together with three known megastgmane glucosides, and two aliphatic and three phenolic compounds. Their structures were elucidated through a combination of spectroscopic analyses and application of the modified Mosher's method. (C) 2008 Elsevier Ltd. All rights reserved.
