Abstract

Antibacterial activity profiles of 22 seed extracts against five pathogens were evaluated using disc diffusion assay. Helenium flexuosum, Helenium autumnale, Epilobium angustifolium, Epilobium coloratum and Epilobium glandulosum showed activity against Staphylococcus aureus, Enterobacter aerogenes, Shigella flexneri and Pseudomonas aeruginosa. The two Helenium species exhibited moderate activity. Bioassay guided chemical examination of H. autumnale and afforded the flavonoids apigenin and luteolin of which luteolin showed weak activity against S. aureus.

 

Key words: Antibacterial, Helenium autumnale, flavonoid, apigenin, luteolin.
