Abstract
Three new ferulic acid esters of glucosylglucose, 1-O-(E)-feruloyl-β-d-glucopyranosyl (1-2)-[β- d-glucopyranosyl (1-6)]-β-d-glucopyranose (allimacronoid A, 1), 1-O-(E)-feruloyl-{β-d-glucopyranosyl (1-4)-[β-d-glucopyranosyl (1-2)]}-[β- d-glucopyranosyl (1-6)]-β-d-glucopyranose (allimacronoid B, 2), and 1-O-(E)-feruloyl-{β-d-glucopyranosyl (1-6)-[β-d-glucopyranosyl (1-2)]}-[β- d-glucopyranosyl (1-6)]-β-d-glucopyranose (allimacronoid C, 3) were isolated together with tuberonoid A (4), from the leaves of Allium macrostemon Bunge. The chemical structures were elucidated based on the analyses of the spectroscopic and chemical data.
