From the leaves of Eucalyptus rostrata, two new acylated flavonol glycosides were isolated together with quercetin 3-0-a-arabinopyranoside-2"-gallate and quercetin 4'-O-b-D-glucopyranoside. The structures of the new compounds were identified as quercetin 4'-O-/I-D-glucopyranoside-6"-gallate and kaempferol 3-O-xarabinopyranoside-2"-gallate.
