摘要：

A new acylated glycoside, 4-O-(4',6'-di-O-galloyl-beta-D-glucopyranosyl)-trans-p-coumaric acid, named microcoryn (1), together with sixteen known phenolic compounds, 5-O-(6'-O-galloyl-beta-D-glucopyranosyl)-gentisic acid (2), ellagic acid (3), gallic acid (4), kaempferol (5), quercetin (6), 3-O-galloyl-beta-D-glucose (7), 2,3,6-tri-O-galloyl-beta-D-glucose (8), 1,2,4,6-tetra-O-galloyl-beta-D-glucose (9), 1,2,3,4,6-penta-O-galloyl-beta-D-glucose (10), 4,6-hexahydroxydiphenoyl-beta-D-glucose (11), gemin D (12), tellimagrandin 1(13), tellimagrandin 11 (14), isocoriariin F (15), oenothein C (16), and oenothein B (17) were isolated from the leaves of Eucalyptus microcorys. The structure of the new compound was elucidated by spectroscopic data, especially by 2D NMR techniques. This is the first phytochemical investigation of this plant's leaf extract.
