摘要：
Two new sesquiterpene lactone xylosides, derivatives of the guaianolides 9 alpha-hydroxyleucodin and 9 alpha-hydroxy-11, 13-dehydroleucodin, were isolated from roots of Lactuca triangulata. Their structures were established on the basis of H-1 and C-13 NMR spectra, 2D NMR (HMQC, HMBC, COSY, NOESY) techniques and comparison with the literature data. The compounds represent the first example of sesquiterpene lactone xylosides. Copyright (C) 2008 John Wiley & Sons, Ltd.
