Two new flavones were isolated from the medicinal plant Calliandra cal
ifornica, 7,2',4',5'-tetramethoxyflavone [1] and 5-hydroxy-7,2',4',5'-
tetramethoxyflavone [2]. The structures were determined from spectral
evidence and both compounds were synthesized. Compound 2 exhibited ant
imicrobial activity for two rest bacterial strains.
