| Summary: | This research was carried out to study the antibacterial activity of ten species of Malay traditional vegetables against
some species of bacteria that were pathogenic to human such as Escherichia coli, Pseudomonas aeruginosa, Salmonella
typhimurium and Staphylococcus aureus, The ten species of table salads (ulam) used in this research were Averrhoa bilimbi L., Etlingera elatior, Vigna sinensis, Centella asiatica, Parkia speciosa, Diplazium esculentum, Manihot esculenta,
Mentha arvensis L., Oenanthe javanica and Cosmos caudatus, The antibacterial activity was done by using disc diffusion
method The result showed that all the sample extracts except Parkia speciosa inhibited the growth of Staphylococcus
aureus and Salmonella typhimurium, For the Escherichia coli, only Averrhoa bilimbi L., Vigna sinensis, Centella asiatica
and Diplazium esculentum inhibit the growth of these bacteria, In addition, all samples inhibit the growth of Pseudomonas
aeruginosa except Parkia speciosa and Mentha arvensis L. Extracts of Etlingers elatior showed the highest antibacterial
activity against Pseudomonas aeruginosa with 10,1 mm diameter of inhibition zone while Centella asiatica show the
lowest antibacterial activity against Pseudomonas aeruginosa with 2.2 mm diameter of inhibition zone, Besides, the
Etlingera elatior, Parkia speciosa, Manihot esculenta, Mentha arvensis L., Oenanthe javanica and Cosmos caudatus
showed a negative result for the antibacterial test onto the gram-negative bacteria Escherichia coli. |
