Aims: The goal of this work was to get the stem extract of Tinospora crispa (L.) using ultrasoundassisted extraction (UAE) with duration and amplitude changes to achieve optimal extraction conditions. The antioxidant potential of the extract as measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH), CUPRAC (Cupric Ion Reducing Antioxidant Capacity), FRAP (Ferric Reducing Ability of Plasma), and its antidiabetic potential. Results: The third test of antioxidant methods showed that the measurement of antioxidant activity with, DPPH, CUPRAC, and FRAP gave significantly different results, but CUPRAC and FRAP gave the same response to the ethanol extract of Tinospora crispa stems, it can be concluded that the extract of Tinospora crispa stems in all treatments had strong antioxidant activity using either the CUPRAC or methods FRAP. In addition, it is very active as an antidiabetic by inhibiting alpha glucosidase. The optimum extract selected was extract B (extraction time was 35 minutes and amplitude 65\%) with IC50 values for antioxidant activity in the CUPRAC method of 72.53 {\textpm} 0.18 mg/L and the FRAP method of 152.29 {\textpm} 2.16 mg/L, while the inhibition of alpha glucosidase was 0.30 {\textpm} 0.006 mg/L.

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.

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.
