Gossypin, a naturally occurring polyhydroxy flavonoid, when subjected to in vitro cytotoxic screening against vero cell lines exhibited 68.75% inhibition at a concentration of $1000{mu}g$. When tested against five bacteria and five fungi, the flavone derivative showed a moderate activity against Staphylococcus aureus and Escherichia coli, mild inhibition against Pseudomonas aerugenosa and Salmonella typhi and no activity against any of the tested fungi, in the concentrations studied.
