ABSTRACT
A new flavonoid glycoside, (-)-2S-8-methyl-5,7,4'-trihydroxyflavanone-7-O-β-D-glucopyranoside (1), along with five known ones, quercetin-3-O-(2"-galloyl)-α-L-arabinoside (2), kaempferol-3-O-α-L-arabinoside (3), guaijaverin (4), trifolin (5) and hyperin (6), was isolated from the leaves of Eucalyptus robusta. Their structures with absolute configurations were elucidated by NMR, HR-ESI-MS, CD spectra data and physicochemical methods. In addition, 2-6 were isolated from E. robusta for the first time.
