- Note: diameter of the antibacterial disc is 6 mm. Results are expressed as means ± SD obtained from 3 independent experiments. aAll extracts were inactive against Gram negative bacteria (Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 10031, Pseudomonas aeruginosa ATCC 10145, Enterobacter aerogenes obtained from Institute for Medical Research Malaysia) tested. bObtained from Faculty of Medicine and Health Sciences UPM. "-" indicates no inhibition activity. "n.t" represents not tested.
