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.

Background: \“Julang-jaling\” (Archidendron bubalinum (Jack) I.C Nielsen) fruits are commonly used as traditional food and in the treatment of blood sugar and heart disease. However, the research about the phytochemicals of the parts of this plants and their bioactivity was rare. Objective: The recent study was aimed to analyze volatile compounds in the extract of \“julang-jaling\” husks and evaluate their antioxidant and antimicrobial activities. Material and methods: The extraction was conducted using n-hexane, ethyl acetate, and methanol as extracting agent. The phytochemical assay was performed for all extracts, and followed by volatile compound analysis using GC-MS. The antioxidant assay was performed using DPPH method, and the antimicrobial activity was conducted using agar disc diffusion method. Results: The phytochemical assay showed that all extracts of \“julang-jaling\” husks contain various phytoconstituents having potential bioactivity. All extracts exhibit antioxidant activity with different level of activity depend on the type of extract. The IC50 value were 273.57 ppm, 324.913 ppm, 735 ppm, for ethyl acetate, methanol and n-hexane, respectively. All extracts were able to inhibit the growth of Bacillus cereus, with the highest antimicrobial activity was gained for ethyl acetate extract. Both ethyl acetate and methanolic extract have antimicrobial activity toward E. coli, but no extracts yield positive results for Aspergillus flavus and Aspergillus niger. Conclusion: GC-MS analysis revealed the presence of hexadecanoic acids and their ester form in all extract, which might largely contribute in the antioxidant and antimicrobial activity.
