- Abstract
Two new glucose esters of caffeic acid, 1-O-(E)-caffeoyl-β-d-glucopyranosyl-(12)-[β-d-glucopyranosyl-(16)]-β-dglucopyranose (allimacronoid A-2, 1) and 1-O-(E)-caffeoyl-{β-d-glucopyranosyl-(14)-[β-d-glucopyranosyl-(12)]}-[β-dglucopyranosyl-(16)]-β-d-glucopyranose (allimacronoid B-2, 2) were isolated from the leaves of Allium macrostemon Bunge. The chemical structures were elucidated based on the analyses of the spectroscopic and chemical data.
