This polysaccharide commonly is extracted from marine brown seaweed. There is lack of information on the fucoidan extracted from tropical brown algae and its anti-cancer activity.&lt;strong&gt; Objectives:&lt;/strong&gt; The objectives of this study were to purify fucoidan from &lt;em&gt;Sargassum &lt;/em&gt;sp&lt;em&gt;., Turbinaria &lt;/em&gt;sp&lt;em&gt;.&lt;/em&gt; and &lt;em&gt;Padina &lt;/em&gt;sp., and to evaluate their cytotoxicity against breast cancer (MCF-7) and colon cancer cells (WiDr). &lt;strong&gt;Materials and Methods:&lt;/strong&gt; Fucoidan extraction was conducted by using acid extraction method. Purified fucoidans were obtained by DEAE cellulose column chromatography and confirmed by HPLC and FT-IR spectrometry. The cytotoxicity was evaluated by using the MTT (3-[4,5-dimethylthiazol-2-yl] -2,5- diphenyltetrazolium bromide) assay. &lt;strong&gt;Results:&lt;/strong&gt; Fucoidan from &lt;em&gt;Sargassum&lt;/em&gt; sp. and &lt;em&gt;Turbinaria&lt;/em&gt; sp. showed low cytotoxicity with IC&lt;sub&gt;50&lt;/sub&gt; ranging between 461-663 &lt;em&gt;&amp;mu;g&lt;/em&gt;/mL. Higher cytotoxicity against MCF-7 and WiDr was showed by fucoidan from Padina sp. with IC&lt;sub&gt;50&lt;/sub&gt; of 144 and 118 &lt;em&gt;&amp;mu;g&lt;/em&gt;/mL, respectively. While its IC&lt;sub&gt;50&lt;/sub&gt; against Vero cells was 501 &lt;em&gt;&amp;mu;g&lt;/em&gt;/mL.Standard fucoidan from Fucus vesiculosus exhibited IC&lt;sub&gt;50&lt;/sub&gt; of 60, 63 and 211 &lt;em&gt;&amp;mu;g&lt;/em&gt;/mL against MCF-7, WiDr and Vero Cells, respectively. Although the IC&lt;sub&gt;50&lt;/sub&gt; was higher than that of standard fucoidan, &lt;em&gt;Padina&lt;/em&gt; sp. fucoidan showed cytotoxicity comparable with standard fucoidan at concentrations below 100 &lt;em&gt;&amp;mu;g&lt;/em&gt;/mL. &lt;b&gt;Conclusion:&lt;/b&gt; These results indicated that &lt;em&gt;Padina&lt;/em&gt; sp.fucoidan showed potential selective cytotoxicity, and promising for the development of an anti-cancer compound.&lt;/p&gt;
