Hook. f &amp;amp; Thomson through the application of ultrasound-assisted extraction (UAE) with variations in time and amplitude to produce optimal extraction conditions. The extract's potential as an anti-gout. &lt;strong&gt;Results: &lt;/strong&gt;The yield of crude ethanol extract of &lt;em&gt;Tinospora crispa &lt;/em&gt;(L.) Hook. f &amp;amp; Thomson obtained from the UAE process ranged from 4.49% to 10.60%. The phytochemical test results of&lt;em&gt; Tinospora crispa &lt;/em&gt;stem extract contain saponins, tannins and alkaloids. Extract C was treated for 45 minutes and had an amplitude of 60% with a total phenolic content of 981.37 ± 0.7 mg/L and a reduction of uric acid level of 53.22 ± 0.1%.&lt;strong&gt; Conclusion&lt;/strong&gt;: The ethanol extract of the &lt;em&gt;Tinospora crispa&lt;/em&gt; stem from the UAE has the potential as a source of anti-gout.&lt;/p&gt;
