UJI AKTIVITAS ANTIOKSIDAN ETANOL BUAH TIN (Ficus carica) DENGAN METODE DPPH DAN FRAP
Indonesia as a developing country has limitations in overcoming health problems. Based on the 2018 National Basic Health Research (Riskesdas), the prevalence of degenerative diseases is increasing. The main cause of death was stroke (15.4%) followed by hypertension, diabetes mellitus, and tumors. One of the causes of this degenerative disease is oxidative stress, namely the large number of oxidants in the body through an oxidation process. Antioxidants are compounds that prevent or postpone oxidation reaction of a molecule by inhibiting initiation or propagation process of the chain oxidation reaction The chemical structure of antioxidants, free radical sources, and physico-chemical properties of different sample preparations can provide various antioxidant activity test results. Therefore, a selective antioxidant activity analysis method is needed for a certain type of sample. The purpose of this study was to test the antioxidant activity of the ethanol extract of fig fruit using the DPPH and FRAP. Methods This research was conducted using the antioxidant activity test method DPPH and FRAP. Based on the research results of antioxidant activity using the DPPH method, the IC50 value of the ethanol extract of fig fruit was 121.74 μg/mL and the FRAP method obtained a value of 11.11 mgAAE/g extrac
Senyawa Antiinflamasi dari Fraksi Etil Asetat Akar Pandan Wangi (Pandanus amaryllifolius Roxb.) Terhadap Udema Kaki Mencit Terinduksi Karagenan
Inflammation can occur due to insect bites, toxins, burns and blows. Inflammation can be cured using Non-Steroid Anti-Inflammatory Drugs (OIANS). Fragrant pandan root is thought to have anti-inflammatory activity because it contains alkaloids and flavonoid compounds. This study aims to determine the activity and characteristics of anti-inflammatory compounds from extracts, fractions and isolates of ethyl acetate root of fragrant pandan (Pandanus amaryllifolius Roxb.) against carrageenan-induced foot edema of mice. The process of isolation of fragrant pandan roots includes stages such as maceration, partitioning and chromatography. The results of the study The methanol extract had good activity at a dose of 200 mg/kg BB for a period of time (t3) 51.7%; the methanol fraction had good activity at a dose of 200 mg/kg BB in the time span (t3) 38.2%; the ethyl acetate fraction had good activity at a dose of 200 mg/kg BB over a period of time (t3) 56.9%; the dichloromethane fraction had good activity at a dose of 200 mg/kg BB in the time range (t3) 59.2%; the n-Hexane fraction had good activity at a dose of 200 mg/kg BB for a period of time (t3) 37.1%; and isolates had good activity at a dose of 50 mg/kg BB over a period of time (t3) 35.6%. K2 isolate from the ethyl acetate fraction was characterized using 1H-NMR with DMSO solvent at a frequency of 500 MHz and 13C-NMR with DMSO solvent at a frequency of 125 MHz. K2 isolate from the ethyl acetate fraction had similarities to Pandalisines A

Studi Penambatan Molekuler Senyawa Tectoquinone Terhadap Enzim α-Glukosidase
The investigation focused on conducting an in silico screening of chemical compounds isolated from Syzygium oblanceolatum (C.B.Rob) to identify potential bioactive compounds that could act as inhibitors of α-Glucosidase. This screening involved tectoquinone as the potential inhibitor for α-Glucosidase and employed the Autodock Vina Docking process. The target enzyme, α-Glucosidase, was used as the receptor with 20 binding sites on the enzyme receptor 1LWJ and the Autodock Vina program was utilized for this purpose. The values of ∆Gbind and the lowest RMSD were determined for each of the 20 targeted binding sites on 1LWJ, representing the free energy change (∆G) resulting from the docking. The docking results demonstrated that the free energy change (∆G) for the 20 targeted binding sites ranged from -6.346 kcal/mol to -9.720 kcal/mol. The most favorable free energy change (∆G) was observed at the 16th binding site with a value of -9.720 kcal/mol, while the highest was recorded at the 18th binding site with a value of -6.346 kcal/mol
