The demand for natural antioxidants is rising due to concerns over synthetic alternatives. &lt;strong&gt;Objectivity:&lt;/strong&gt; To determine the total phenolic content (TPC) and antioxidant activity of &lt;em&gt;S. myrtifolium&lt;/em&gt; leaf extracts obtained with various solvents (ethanol 60, 70, 80, 96% v/v, ethyl acetate, n-hexane) and two extraction methods (maceration and ultrasonic-assisted extraction, UAE), and to assess the effects of solvent polarity and extraction method. &lt;strong&gt;Methods: &lt;/strong&gt;Leaves were extracted by maceration and UAE. TPC was measured via the Folin–Ciocalteu method (tannic acid equivalents, %) using UV–Vis spectrophotometry. Antioxidant activity was evaluated using the DPPH assay (IC₅₀). Phytochemical screening was also performed. &lt;strong&gt;Results:&lt;/strong&gt; TPC (maceration): 60% ethanol = 18.76%, 96% ethanol = 13.64%, ethyl acetate = 8.33%, n-hexane = 0.83%. TPC (UAE): 60% ethanol = 20.02%, 96% ethanol = 14.04%, ethyl acetate = 10.13%, n-hexane = 0.92%. Solvent type/concentration and extraction method significantly affected TPC (&lt;em&gt;p&lt;/em&gt; &amp;lt; 0.05). UAE 96% ethanol showed the strongest antioxidant activity (IC₅₀ ≈ 16.03 ppm), ethyl acetate had moderate activity (≈67–76 ppm), and n-hexane the weakest (≈153–163 ppm). UAE 60% ethanol had the highest TPC but not the strongest activity (IC₅₀ ≈ 88.27 ppm), suggesting antioxidant potency depends on phenolic composition. &lt;strong&gt;Conclusion: &lt;/strong&gt;UAE with 60% ethanol produced the highest TPC, while UAE with 96% ethanol exhibited the strongest antioxidant activity. Further profiling is needed to clarify the phenolic composition–activity relationship.&lt;/p&gt;

Kurz (RnLK) leaf extract. The Ultrasound-Assisted Extraction (UAE) technique was used to extract the leaf material, and the solvent used was ethanol with a 70% concentration. The total phenol content (TPC) of the extracted material was determined. The Cupric Ion Reducing Antioxidant Capacity (CUPRAC) method was used to examine antioxidant activity, whereas α-glucosidase activity was used to test antidiabetic action.&lt;strong&gt; Results:&lt;/strong&gt; The ethanol extract of RnLK leaves yielded 8.36%, with a TPC of 607.1±0.2 mg GAE/g sample. The IC&lt;sub&gt;50&lt;/sub&gt; value for leaf extract antioxidant activity was 19.1±0.1 mg/L. Furthermore, the leaf extract inhibits α-glucosidase activity and has an IC&lt;sub&gt;50&lt;/sub&gt; value of 81.3±3 mg/L, making it an antidiabetic. &lt;strong&gt;Conclusion:&lt;/strong&gt; The ethanolic extract of RnLK leaves can be used as an alternative antioxidant and antidiabetic material, according to the findings of this study.&lt;/p&gt;

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 &lt;em&gt;Musa balbisiana&lt;/em&gt; 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 IC&lt;sub&gt;&lt;sup&gt;50&lt;/sup&gt;&lt;/sub&gt; values of 150.24 ± 0.0348 mg/L and 227.80 ± 0.0986 mg / L, respectively. The total phenolic content value of 625.64 ± 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.&lt;/p&gt;
