The leaves are a popular flavoring in Southeast Asia, especially in the northeast of Thailand.&amp;nbsp; The objectives of this study were to determine the major constituents of the leaves of &lt;em&gt;T. triandra&lt;/em&gt;, and assess their anticancer activities against human cancer cell lines. &lt;strong&gt;Methods&lt;/strong&gt;: The leaves were extracted by a soxhlet apparatus with petroleum ether, dichloromethane, ethyl acetate and water. Major constituents were then purified and identified using chromatographic procedures and various spectroscopic techniques.&amp;nbsp; &lt;em&gt;In vitro&lt;/em&gt; anticancer activity tests of &lt;em&gt;T. triandra&lt;/em&gt; extracts were performed by resazurinmicroplate assay (REMA), and tested with 3 cell lines: oral cavity cancer (KB), lung cancer (NCI-H187) and breast cancer (MCF-7) cell lines. &lt;strong&gt;Results&lt;/strong&gt;: The result indicated that the main compound of &lt;em&gt;T. triandra&lt;/em&gt; leaves was oxoanolobine. The methanol extract showed the highest cytotoxic activity against lung cancer (NCI-H187) cell line whereas the water extract exhibited the highest activity against oral cavity cancer (KB) cell line. The IC&lt;sub&gt;50&lt;/sub&gt; of oxoanolobine against the NCI-H187 cell line was 27.60 &amp;plusmn; 4.30 &amp;micro;g/mL. &lt;strong&gt;Conclusion:&lt;/strong&gt;&amp;nbsp; &lt;em&gt;T. triandra&lt;/em&gt; leaves contain oxoanolobine as the major constituent and have the potential of anticancer activity but are required to be investigated further.&lt;/p&gt;
