Abstract
Two new ferulic acid esters of oligo-glucose, 1-Ο-(E)-feruloyl-β--D-gentiobioside (1) and 1-Ο-(E)feruloyl-{β-D-glucopyranosy (1->6)-[β-D-glucopyranosyl (I--2)]}-β-D-glucopyranoside.(allimacronoid D, 2) were isolated together with 1-Ο-(E)-feruloyl-β-D-glucopyranoside (3) and trans-ferulic acid (4) from the leaves of Allium macrostemon Bunge. The chemical structures were elucidated based on the analyses of the spectroscopic and chemical data.
