Remarks on result:
other: all strains/cell types tested

Any other information on results incl. tables

No bacteriotoxic effects up to 158 µg/plate; total bacterial count remained unchanged an no growth inhibition was seen.

At doses above 158 µg/plate strain-specific cytotoxicity.

Compound precipitation started at 500 µg/plate; and 5000 µg/plate could not be used for evaluation.
