Abstract
Study antimicrobial activity from the crude extracts of Wedelia chinensis tree to demonstrate the role of the plant in the treatment of diseases by traditional methods. The results showed that the extracted liquid from the trunks and leaves of Wedelia chinensis are resistant to S. aureus, S. marcescens, S. lutea, E. coli in vitro at concentrations ranging from 2.0 - 4.0 grs/ml. The highest antimicrobial activity was found for S. lutea, followed by S. aureus, S. marcescens and E. coli. The antimicrobial activity from Wedelia chinensis crude extracts of trunks and leaves is not affected by the temperature and the activity retains over 80% at 100°C for a period of 20 minutes.
