Preliminary screening of far-eastern ethnomedicinal plants for antibacterial activity.

The results of antibacterial screening of 308 ethanol extracts from 250 wild far-eastern plants belonging to 77 families are reported. Antibacterial activity of plant extracts was tested in vitro by the filter-paper disc assay method. The plants screened were reported to be used by the population of the Soviet Far East against some bacterial infections. Activity against gram-positive as well as gram-negative groups of microorganisms was tested.
