Abstract

Phytochemical studies of two Australian Anigozanthos (kangaroo paw) species, A. rufus and A. pulcherrimus, resulted in the identification of 13 secondary metabolites. 2-Amino-6-O-p-coumarylheptanedioic acid (3) and chalcone-5′-O-(4-O-p-coumaryl)-O-β-D-glucopyranoside (12) are reported as new compounds and are accompanied by nine flavonoids (2, 5−11,13) and two anthocyanins (1, 4). Compounds 1 and 4 were isolated as red solids from A. rufus and are likely responsible for the coloration of the flowers. Compounds 1, 3, and 6 showed weak antimicrobial activities against Acinetobacter baumannii ATCC 19606 at concentrations of 52.4, 94.9, and 53.9 μM, respectively.
