However, the high ascorbic acid levels in Kakadu plum fruit may interfere with this activity. &lt;strong&gt;Methods: &lt;/strong&gt;&lt;em&gt;T. ferdinandiana&lt;/em&gt; leaf solvent extracts were investigated by disc diffusion assay against a panel of bacteria known to trigger autoimmune inflammatory diseases.Their MIC values were determined to quantify and compare their efficacies. Toxicity was determined using the&lt;em&gt; Artemia franciscana&lt;/em&gt; nauplii bioassay. Non-targeted HPLC separation of crude extracts coupled to high resolution time-of-flight (TOF) mass spectroscopy with screening against 3 compound databases was used for the identification and characterisation of individual components in crude plant extracts. &lt;strong&gt;Results:&lt;/strong&gt; Methanolic, aqueous and ethyl acetate&lt;em&gt; T. Ferdinandiana&lt;/em&gt; leaf extracts displayed potent antibacterial activity in the disc diffusion assay against the bacterial triggers of rheumatoid arthritis, ankylosing spondylitis and multiple sclerosis. The ethyl acetate extract had the most potent inhibitory activity, with MIC values less than 120 &amp;mu;g/ml against&lt;em&gt; P. mirabilis&lt;/em&gt; and &lt;em&gt;A. baylyi&lt;/em&gt; (both reference and clinical strains). The ethyl acetate extract had similar potency against K. &lt;em&gt;pneumonia&lt;/em&gt;(both reference and clinical strains), but had higher MIC values (2733 &amp;mu;g/ml) against P. &lt;em&gt;aeruginosa&lt;/em&gt;. The methanolic extract was also a potent inhibitor of bacterial growth, with MIC values generally &amp;lt; 1000 &amp;mu;g/ml. In comparison, the water, chloroform and hexane leaf extracts were all substantially less potent antibacterial agents, with MICs values generally well over 1000 &amp;mu;g/ml. All T. &lt;em&gt;ferdinandiana&lt;/em&gt; leaf extracts were either nontoxic or of low toxicity in the&lt;em&gt; Artemia fransiscana &lt;/em&gt;bioassay.Non-biased phytochemical analysis of the ethyl acetate extract revealed the presence of high levels of tannins (exifone (4-galloylpyrogallol), ellagic acid dehydrate, trimethylellagic acid, chebulic acid, corilagin, punicalin, castalagin and chebulagic acid). &lt;strong&gt;Conclusion:&lt;/strong&gt; The low toxicity of the T. &lt;em&gt;ferdinandiana&lt;/em&gt; leaf extracts and their potent inhibitory bioactivity against the bacterial triggers of autoimmune inflammatory disorders indicates their potential as medicinal agents in the treatment and prevention of these diseases.&lt;/p&gt;&lt;p style=&quot;text-align:justify&quot;&gt;&lt;strong&gt;Key words: &lt;/strong&gt;&lt;em&gt;Terminalia ferdinandiana&lt;/em&gt;, rheumatoid arthritis, ankylosing spondylitis, multiple sclerosis, &lt;em&gt;Proteus mirabilis, Klebsiella pneumoniae , Acinetobacter baylyi, Pseudomonas aeruginosa.&lt;/em&gt;&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><custom1><style face="normal" font="default" size="100%">R.
