Antimicrobial activity of natural dyes obtained from Alstonia Scholaris barks

Abstract

In the present study to evaluate the antimicrobial activity of Alstonia Scholaris barks. Many of the plant materials, from which natural dyes are obtained, found to have some medicinal values. During the present study, dying materials were prepared from barks of Alstonia Scholaris. The well diffusion method was adopted to examine antimicrobial activity of dying materials against test organisms. The result showed that the dying materials of Alstonia Scholaris was most active for antibacterial (10 mm) and antifungal (11 mm). Results of the present study suggest that the dying material of Alstonia Scholaris has significant antibacterial activity against pathogenic bacteria and fungus.
