Background. Hyperuricemia is a condition characterized by increased uric acid levels due to excessive activity of the xanthine oxidase (XO) enzyme. Arcangelisia flava is known to contain secondary metabolites, such as flavonoids, alkanoids, and terpenoids, which have been reported to exhibit potential inhibitory effects on XO. This study aims to determine the effect of variations in ethanol sol…
Background: Arcangelisia flava, commonly known as yellow wood, is an Indonesian medicinal plant containing bioactive compounds such as phenols and flavonoids, which act as natural antioxidants. The antioxidant activity of plant extracts is strongly influenced by the type and concentration of solvent used during extraction. Therefore, selecting the optimal solvent concentration is essential to o…
Latar belakang: Kayu kuning memiliki kandungan metabolit sekunder berupa flavonoid yang diteliti dapat menghambat enzim xantin oksidase yaitu enzim yang mengkatalisis pembentukan asam urat sehingga berpotensi sebagai pengobatan alternatif hiperurisemia. Tujuan: Untuk mengetahui efek inhibisi fraksi etil asetat dari ekstrak etanol 96% batang kayu kuning terhadap enzim xantin oksidase Metode: Sim…
Background: Xanthine oxidase is an enzyme that catalyzes the formation of uric acid. Secondary metabolites that have a potential as xanthine oxidase inhibitor or antihyperuricemia are flavonoids, alkaloids, terpenoids, saponins, and tannins. From the latest research, ethanol extract of the stem of kayu kuning contains secondary metabolites such as flavonoids, alkaloids, terpenoids, saponins, an…
