This study examines the anti-proliferative activity of &lt;em&gt;T. carpentariae&lt;/em&gt; leaf and &lt;em&gt;T.&lt;/em&gt; &lt;em&gt;grandiflora&lt;/em&gt; leaf, fruit and nut extracts against Caco-2 and HeLa carcinoma proliferation. Materials and Methods: Powdered &lt;em&gt;T. carpentariae&lt;/em&gt; leaf and T.&lt;em&gt; grandiflora&lt;/em&gt; leaf, fruit and nut were extracted and tested for anti-proliferative activity against Caco-2 and HeLa cancer cell lines using colorimetric cell proliferation assays. Toxicity was evaluated using an Artemia franciscana nauplii bioassay. The extract with the most potent anti-proliferative activity was examined using GCMS analysis and triterpenoid compounds were identified by comparison with a compound database. Results: &lt;em&gt;T. carpentariae&lt;/em&gt; leaf and T. &lt;em&gt;grandiflora &lt;/em&gt;leaf, fruit and nut extracts displayed potent anti-proliferative activity against Caco-2 and HeLa carcinoma cells. The &lt;em&gt;methanolic T. grandiflora &lt;/em&gt;leaf extract was particularly effective at blocking the proliferation of the colorectal carcinoma Caco-2 (IC50 = 372 &amp;mu;g/mL). The methanol &lt;em&gt;T. carpentariae &lt;/em&gt;and &lt;em&gt;T.&lt;/em&gt; &lt;em&gt;grandiflora&lt;/em&gt; leaf extracts were similarly potent inhibitors of HeLa cervical cancer cell proliferation with IC50 values of 864 and 833 &amp;mu;g/mL respectively. The methanolic T. &lt;em&gt;grandiflora&lt;/em&gt; fruit and nut extracts, as well as all aqueous and ethyl acetate extracts, were moderate to good inhibitors of carcinoma proliferation. In contrast, chloroform and hexane extracts were generally devoid of anti-proliferative activity. The&lt;em&gt; methanolic T.&lt;/em&gt; &lt;em&gt;grandiflora&lt;/em&gt; extracts displayed low toxicity in the Artemia nauplii bioassay. All other extracts were non-toxic. GC-MS analysis of the methanolic T. &lt;em&gt;grandiflora&lt;/em&gt; leaf extract identified 3 lanostane and 2 pentacyclic triterpenoids. Conclusion: The low toxicity and anti-proliferative activity observed with the &lt;em&gt;T. carpentariae &lt;/em&gt;and T. &lt;em&gt;grandiflora&lt;/em&gt; extracts against Caco-2 and HeLa indicate their potential for the prevention and treatment of some cancers.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">441</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Reece Courtney&lt;sup&gt;1,2&lt;/sup&gt;, J.
