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.

Aims: This study aimed to obtain the stem extract of Tinospora crispa (L.) Hook. f \& Thomson 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 anti-gout. Results: The yield of crude ethanol extract of Tinospora crispa (L.) Hook. f \& Thomson obtained from the UAE process ranged from 4.49\% to 10.60\%. The phytochemical test results of Tinospora crispa 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 {\textpm} 0.7 mg/L and a reduction of uric acid level of 53.22 {\textpm} 0.1\%. Conclusion: The ethanol extract of the Tinospora crispa stem from the UAE has the potential as a source of anti-gout.

Plant extracts or their secondary metabolites have functioned as antioxidants in phytotherapy drugs which function as protection against various diseases related to oxidative stress and free radicals. Free radicals play an important role in the initiation and development of various diseases, one of which is uric acid. Hhis study aims to obtain ethanolic extract from the ripe fruit of Musa balbisiana Colla using the UAE method and obtain information about secondary metabolites and their bioactivity as antioxidants and anti-gout. The results showed that antioxidant activity test using the DPPH and FRAP methods gave IC50 values of 150.24 {\textpm} 0.0348 mg/L and 227.80 {\textpm} 0.0986 mg / L, respectively. The total phenolic content value of 625.64 {\textpm} 0.36 mg GAE/g ethanolic extract is thought to have a role in high antioxidant activity. In addition, ethanol extract with a concentration of 50 mg / L has activity in reducing uric acid levels by around 9\%. It can be concluded that the ethanolic extract produced by UAE has potential as a source of anti-oxidants and anti-gout.
