In gout, an increase in uric acid in the blood triggers the formation of crystals, causing joint pain. Indonesia is a country rich in the biodiversity of medicinal plant species. Therefore, its flora offers promising therapy for gout, one of which is&lt;em&gt; Andrographis paniculata &lt;/em&gt;Nees. This study aims to obtain the leaf extract of &lt;em&gt;A. paniculata &lt;/em&gt;through the application of ultrasound-assisted extraction (UAE) with variations in time and amplitude to produce optimal extraction conditions. Then the extract obtained was subjected to phytochemical screening, a total phenolic content test and uric acid test. The results of phytochemical screening of &lt;em&gt;A. paniculata&lt;/em&gt; leaf extract using UAE contained saponins, phenols, tannins and alkaloids. The high total phenolic content has an effect on the high potential for reducing uric acid levels. Sample B with a time variation of 35 minutes and an amplitude of 65% showed the highest total phenolic content and potential for reducing uric acid levels compared to the other samples, which were 1104.53 ± 0.5 mg GAE/g extract and 72.81±0.2 %, respectively. From the results of the study, it can be concluded that the UAE extract from the leaves of &lt;em&gt;A. paniculata&lt;/em&gt; has good potential as an anti-gout agent.&lt;/p&gt;
