The antioxidant activity found in Musa balbisiana Colla may be related to anti-gout activity, where

Fragrance seeds are produced from a combination of various kinds of raw materials, both natural and synthetic. One of the synthetic raw materials added in making fragrances is Schiff base. In this study, aurantiol Schiff base was made from raw material of methyl anthranylate and hydroxy citronellal by simple condensation at 110°C for 30 minutes. The color of the product obtained is observed and compared to the standard color, which is dark yellow. Furthermore, characterization was carried out using gas chromatography and mass spectrophotometry. The chromatogram results showed that aurantiol with the molecular formula C 18 H 27 NO 3 had similarities above 90%.

The utilization of stone bananas is still very minimal, especially banana peels which will only end up as waste. Despite the fact that stone bananas are a fruit high in metabolites, they have numerous health benefits.The banana peels (Musa balbisiana Colla) was extracted with ultrasound-assisted extraction to determine the content of secondary metabolites, total fernol, antioxidant capacity using the DPPH and FRAP methods, as well as the potential for antigout activity in the extract. Ultrasound-assisted extraction is a less expensive, simpler, and more reliable alternative to traditional extraction methods. Musa balbisiana Colla banana peel extract contains alkaloids, saponins, tannins, steroid glycosides and phenols as secondary metabolites. The results obtained from determining the total phenol content was 397.50±0.41 GAE/g sample. Then the results of testing for free radical scavenging activity with the DPPH and FRAP methods showed IC50 values of 143.97±0.17mg/L and 151.08± 0.32mg/L, respectively. Meanwhile the antigout activity was obtained 27.95±0.08% which was greater than Alupurinol, so that Musa balbisiana Colla banana peel has the potential as an alternative compound to reduce uric acid levels.

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 IC 50 values for antioxidant activity in the CUPRAC method of 72.53 ± 0.18 mg/L and the FRAP method of 152.29 ± 2.16 mg/L, while the inhibition of alpha glucosidase was 0.30 ± 0.006 mg/L.
