[Antibacterial activity of extracts from plants used in preparation as antidiarrheals at Kinshasa, Zaire]. / Activité antibactérienne d'extraits à partir de plantes utilisées en préparations comme antidiarrhéiques à Kinshasa, Zaïre.

ABSTRACT

A preliminary and anterior bacteriological study about 38 plant antidiarrheic traditional preparations, has demonstrated that 35 of them have bactericidal activity. Thirty inhibit the growth of all select germs and 5 exert this bactericidal effect on some germs. Some extracts proceeding of these possess a bactericidal activity, specially if they contain polyphenols (flavonoids, catechics tanins), saponins and alkaloids.
