Two new sesquiterpene lactone glycosides and three new kaurene glycosides closely related to carboxyatractyloside and atractyloside, together with the 3', 4'-didesulphated-carboxyatractyloside and 3', 4'-didesulphated-atractyloside, were isolated from the aerial parts of Xanthium spinosum. Their structures were established by spectroscopic methods (H-1, C-13, DEFT C-13 NMR and FAB mass spectr).

Abstract
Two new sesquiterpene lactone glycosides and three new kaurene glycosides closely related to carboxyatractyloside and atractyloside, together with the 3', 4'-didesulphated-carboxyatractyloside and 3', 4'-didesulphated-atractyloside, were isolated from the aerial parts of Xanthium spinosum. Their structures were established by spectroscopic methods (H-1, C-13, DEFT C-13 NMR and FAB mass spectr).File in questo prodotto:
