Resumo
A new acylated glycoside, 4-O-(4’,6’-di-O-galloyl--D-glucopyranosyl)-trans-p-coumaric acid, named
microcoryn (1), together with sixteen known phenolic compounds, 5-O-(6'-O-galloyl--D-glucopyranosyl)-gentisic acid (2),
ellagic acid (3), gallic acid (4), kaempferol (5), quercetin (6), 3-O-galloyl--D-glucose (7), 2,3,6-tri-O-galloyl--D-glucose
(8), 1,2,4,6-tetra-O-galloyl--D-glucose (9), 1,2,3,4,6-penta-O-galloyl--D-glucose (10), 4,6-hexahydroxydiphenoyl--Dglucose
(11), gemin D (12), tellimagrandin I (13), tellimagrandin II (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.
