Aims: This study aimed to obtain the skin extract of Phaleria macrocarpa (Scheff.) Boerl. through the application of ultrasound-assisted extraction (UAE) with variations in time and amplitude to produce optimal extraction conditions. The extract{\textquoteright}s potential as an antioxidant with 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical inhibition parameters, and its potential as an anti-gout. Results: The yield of crude ethanol extract of Phaleria macrocarpa (Scheff.) Boerl rind obtained from the UAE process ranged from 18 to 21\%. The phytochemical test results of Phaleria macrocarpa fruit peel extract contain phenolic compounds, tannins, saponins, and alkaloids. Extract B was treated for 35 minutes and had an amplitude of 65\% with an antioxidant activity IC50 of 52.01 {\textpm} 0.06 mg/L and a reduction of uric acid level of 90.49 {\textpm} 0.08. Conclusion: The ethanol extract of the fruit peel of Phaleria macrocarpa from the UAE has the potential as a source of antioxidants and anti-gout.

Gout is a type of arthritis that causes painful inflammation in one or more joints. 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 Andrographis paniculata Nees. This study aims to obtain the leaf extract of A. paniculata 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 A. paniculata 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 {\textpm} 0.5 mg GAE/g extract and 72.81{\textpm}0.2 \%, respectively. From the results of the study, it can be concluded that the UAE extract from the leaves of A. paniculata has good potential as an anti-gout agent.

Aims: This study aims to obtain a stem bark extract of Rhinachantus nasutus (L.) Kurz through the application of ultrasound-assisted extraction (UAE) and reveal: the total phenolic content in the extract; The extract{\textquoteright}s potential as an antioxidant with copper-reducing strength parameters, and its potential as an antidiabetic by inhibiting alpha-glucosidase activity. Results: The crude ethanol extract of R. nasutus stem bark obtained from the UAE process was 7.4896 g with a yield of 4.99\%. The high total phenolic content, namely 677.3343{\textpm}0.0007 mg GAE / g sample, the antioxidant activity test using the CUPRAC method gave an IC50 value of 18.43{\textpm}0.20 mg / L. In addition, the ethanol extract of stem bark has a high ability to inhibit the activity of the alpha-glucosidase enzyme with an IC50 value of 10.95{\textpm}0.28 mg / L. Conclusion: The ethanol extract of the stem bark of R. nasutus from UAE has the potential as a source of antioxidants and antidiabetic.
