Antimicrobial screening of ethnobotanically important stem bark of medicinal plants

Pharmacognosy Research, 2010
The stem barks are the rich sources of tannins and other phenolic compounds. Tannins inhibited the growth of various fungi, yeast, bacteria and virus. Hence, ten stem barks of ethnomedicinally important plants were screened for antibacterial and antifungal activities against human pathogenic strains.Air-dried and powdered stem bark of each plant was ...
