Antimicrobial activity of flavonoids from in vitro tissue culture and seeds of Gossypium species

摘要

Flavonoids extracts of seeds and callus tissues of three species of Gossypium (fam. Malvaceae) were screened against Bacillus cerus, Escherchia coli, Mycobacterium smegmatis, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella typhimurium, Staphylococcus aureus, S. epidermidis, Trichoderma viride and Candida albicans adopting disc diffusion method. Results were compared with the zone of inhibition produced by commercially available standard antibiotics. Maximum activity was observed in flavonoid fraction of callus tissue as compared to seeds. Flavonoids extracts did not show any activity against Candida albicans.
