Abstract
Two new flavones, 4′,6,7-trihydroxy-3′,5′-dimethoxyflavone (2) and 5′,5-dihydroxy-3′,4′,8-trimethoxyflavone (3) were isolated from Artemisia giraldii and their structures were identified by spectroscopic methods. These two new flavones showed antibiotic activity against Staphylococcus aureus, Sarcina lutea, Escherichia coli, Pseudomonas aeruginosa, Proteus sp. Aspergillus flavus, and Trichoderma viride.
