Abstract

The dichloromethane extract of the leaves of Araucaria bidwillii afforded a biflavone, 4", 4'", 7, 7'-tetra-O-methylcupressuflavone by silica gel chromatography. Its structure was elucidated by extensive 1D and 2D NMR and mass spectrometry. Antimicrobial tests on the compound indicated that it inhibited the growth of Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. It was inactive against Bacillus subtilis, Candida albicans, Trichophyton mentagrophytes, and Aspergillus niger.
