Although &lt;em&gt;Cakile maritima&lt;/em&gt; has a high antioxidant capacity, it is yet to be tested for the ability to inhibit the proliferation of cancer cells. &lt;strong&gt;Methods&lt;/strong&gt;: Solvent extracts prepared from &lt;em&gt;C. maritima&lt;/em&gt; plant material were analysed for antioxidant capacity by the DPPH free radical scavenging assay. Anti-proliferative activities against Caco&lt;sub&gt;2&lt;/sub&gt; and HeLa cancer cells were determined by an MTS based cell proliferation assay. Toxicity was determined by the Artemia franciscana bioassay. The most potent anti-proliferative extract (hexane) was further investigated using non-targeted GC-MS headspace analysis. &lt;strong&gt;Results&lt;/strong&gt;: Good DPPH radical scavenging activity was calculated for all &lt;em&gt;C. maritima&lt;/em&gt; extracts. The methanolic and ethyl acetate extracts had particularly strong antioxidant activity (IC&lt;sub&gt;50&lt;/sub&gt; of 4.7 and 3.4 μg/mL respectively). Interestingly, the hexane extract which had the lowest DPPH radical scavenging activity (IC&lt;sub&gt;50&lt;/sub&gt; 13.6 μg/mL), was the most potent inhibitor or Caco&lt;sub&gt;2&lt;/sub&gt; and HeLa carcinoma cell growth, with IC&lt;sub&gt;50&lt;/sub&gt;’s of 12 and 126 μg/mL respectively. The ethyl acetate extract was also a potent inhibitor of proliferation (IC&lt;sub&gt;50&lt;/sub&gt; values of 185 and 468 μg/mL against Caco&lt;sub&gt;2&lt;/sub&gt; and HeLa, respectively). The methanolic extract (IC&lt;sub&gt;50&lt;/sub&gt; values of 2261 and 2046 μg/mL against CaCo&lt;sub&gt;2&lt;/sub&gt; and HeLa respectively) displayed only moderate anti-proliferative activity, demonstrating that antioxidant activity did not correspond with anti-proliferative activity. All of the extracts were determined to be nontoxic in the Artemia franciscana bioassay, with LC&lt;sub&gt;50&lt;/sub&gt; values substantially &amp;gt;1000 μg/mL. Non-biased GC-MS headspace analysis of the &lt;em&gt;C. maritima&lt;/em&gt; hexane extract highlighted several interesting compounds that may contribute to the therapeutic bioactivities of the extract. &lt;strong&gt;Conclusion&lt;/strong&gt;: The lack of toxicity and the anti-proliferative activity of the hexane and ethyl acetate &lt;em&gt;C. maritima &lt;/em&gt; extracts against HeLa and Caco&lt;sub&gt;2&lt;/sub&gt; cancer cell lines indicates their potential in the treatment and prevention of some cancers.&lt;/p&gt;

This study examines the anti-proliferative activity of &lt;em&gt;T. sericea&lt;/em&gt; leaf extracts against Caco2 and HeLa carcinoma cell proliferation. &lt;strong&gt;Methods:&lt;/strong&gt; Solvent extracts were prepared from &lt;em&gt;T. sericea&lt;/em&gt; leaves and their antioxidant capacities were determined by the DPPH free radical scavenging assay. Anti-proliferative activities against Caco2 and HeLa cancer cells were determined by an MTS based cell proliferation assay. Toxicity was determined using the &lt;em&gt;Artemia franciscana&lt;/em&gt; nauplii bioassay. &lt;strong&gt;Results:&lt;/strong&gt; The methanolic and aqueous &lt;em&gt;T. sericea&lt;/em&gt; leaf extracts displayed high antioxidant capacities (equivalent to 150 and 340 mg of ascorbic acid per gram of plant material extracted respectively). In contrast, the ethyl acetate, chloroform and hexane extracts had relatively low antioxidant contents (&amp;le;5 mg of ascorbic acid equivalents per gram of plant material extracted). The antioxidant contents of the &lt;em&gt;T. sericea&lt;/em&gt; leaf extracts correlated with the ability of the extracts to inhibit proliferation of Caco2 and HeLa cancer cell lines. The high antioxidant methanolic and aqueous extracts were potent inhibitors of cell proliferation, with IC&lt;sub&gt;50&lt;/sub&gt; values 120-1400 &amp;mu;g/mL. The aqueous &lt;em&gt;T. sericea&lt;/em&gt; leaf extract was particularly effective, with IC&lt;sub&gt;50&lt;/sub&gt; values of 528 and 120 &amp;mu;g/mL against Caco2 and HeLa cells respectively. The methanolic extract also displayed good, albeit substantially less potent, antiproliferative activity against HeLa cells, with an IC&lt;sub&gt;50&lt;/sub&gt; of 1358 &amp;mu;g/mL. In contrast, the lower antioxidant content extracts generally did not inhibit cancer cell proliferation. Cell imaging studies detected morphological features consistent with apoptosis in Caco2 cells exposed to sub-lethal concentrations of the methanolic and aqueous T. sericea leaf extracts, indicating that these extracts are functioning by cytotoxic mechanisms. The aqueous &lt;em&gt;T. sericea&lt;/em&gt; leaf extract displayed low to moderate toxicity in the &lt;em&gt;Artemia franciscana&lt;/em&gt; bioassay, with an LC&lt;sub&gt;50&lt;/sub&gt; value of 737 &amp;mu;g/mL. All other extracts were nontoxic. &lt;strong&gt;Conclusion:&lt;/strong&gt; The antiproliferative activity and low toxicity of the &lt;em&gt;T. sericea &lt;/em&gt;methanolic and aqueous leaf extracts extracts against HeLa and Caco2 cancer cell lines indicates their potential in the treatment and prevention of some cancers.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">408</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;BiYun Gu&lt;sup&gt;1,2&lt;/sup&gt;, Joseph Shalom&lt;sup&gt;1,3&lt;/sup&gt;, Ian E.

Infections result in exotoxin production, tissue necrosis and unless promptly treated, often result in death. &lt;strong&gt;Methods:&lt;/strong&gt; &lt;em&gt;Tasmannia lanceolata&lt;/em&gt; extracts were investigated for &lt;em&gt;C. perfringens &lt;/em&gt;growth inhibitory activity by disc diffusion analysis and MIC determination. Toxicity was evaluated by Artemia nauplii bioassay and the most potent extracts were phytochemically evaluated by GC-MS headspace analysis. &lt;strong&gt;Results:&lt;/strong&gt; All &lt;em&gt;T. lanceolata&lt;/em&gt; berry and leaf extracts displayed potent&lt;em&gt; C. perfringens&lt;/em&gt; growth inhibition. The berry extracts were more potent growth inhibitors than the corresponding leaf extracts, although the leaf extracts were also potent growth inhibitors. The berry aqueous, methanolic and ethyl acetate extracts were particularly potent growth inhibitors, with MIC values of 654, 65 and 329 &amp;mu;g/mL respectively. &lt;em&gt;T. lanceolata &lt;/em&gt;leaf also displayed good efficacy, with an MIC of 839, 1255 and 625 &amp;mu;g/mL for the aqueous, methanolic and ethyl acetate extracts respectively. All extracts were nontoxic in the &lt;em&gt;Artemia franciscana&lt;/em&gt; bioassay, with LC&lt;sub&gt;50&lt;/sub&gt; values substantially &amp;gt; 1000 &amp;mu;g/mL. Non-biased GC-MS analysis of the aqueous, methanolic and ethyl acetate berry extracts revealed the presence of high relative levels of a diversity of terpenoids. &lt;strong&gt;Conclusions:&lt;/strong&gt; The lack of toxicity of the T. lanceolata extracts and their potent growth inhibitory bioactivity against &lt;em&gt;C. perfringens&lt;/em&gt; indicates their potential as medicinal agents in the treatment and prevention of clostridial myonecrosis and enteritis necroticans.
