  Crotonionosides A–G: Megastigmane glycosides from leaves of Croton cascarilloides Räuschel

  摘要：

  From the 1-BuOH-soluble fraction of a MeOH extract of leaves of Croton cascarilloides, collected in Okinawa, Japan, seven megastigmane glycosides, named crotonionosides A-G, were isolated together with three known megastigmane glucosides, dendranthemosides A and B, and citroside A. This structures were elucidated by a combination of spectroscopic analyses, HPLC analyses, and application of the modified Mosher's method. (C) 2010 Elsevier Ltd. All rights reserved.
