Abstract:
Yellow root (Arcangelisia flava) is a liana plant that belongs to the family
Menispermaceae. The extracts from various parts from this yellow root also show several
pharmacological activities that have been studied such as antibacterial. This investigation
aims to assess the antibacterial activity of A. flava plant extracts against Gram-positive
and Gram-negative bacteria including Staphylococcus aureus ATCC 6538, Listeria
monocytogenes ATCC 7644, Bacillus subtillis ATCC 6633, Salmonella Typhimurium
ATCC 14028 and Vibrio alginolyticus ATCC 17749 using diffusion method. The results
of the antibacterial test using the diffusion method revealed that the dichloromethane
extract of yellow root plant (A. flava) at a concentration of 500 ppm had antibacterial
activity in the medium to strong category against four test pathogenic bacteria.
