Indonesia, with its biodiversity, is overgrown by various kinds of plants that have medicinal potential, including Terap (Artocarpus odoratissimus Blanco). The leaves of A. odoratissimus are empirically used by local people of Borneo Island to treat gout. The purpose of this study was to determine the antigout activity of the active compound from A. odoratissimus leaves through xanthine oxidase inhibition using the molecular docking method and to determine the ADMET properties of these compounds. Phytochemical screening showed that A. odoratissimus leaf extract contained alkaloids, flavonoids, steroids/triterpenoids, and phenolics. The results of TLC showed that A. odoratissimus leaf extract contained steroid and flavonoid compounds in the form of stigmasterol and rutin. The results of molecular docking showed that flavan-3-ol provided the lowest bond-free energy against xanthine oxidase with a ΔG value of -8.3 kcal/mol, lower than allopurinol and hypoxanthine as reference ligands. Flavan-3-ol interacts with xanthine oxidase through hydrogen bonding with amino acid residues in the form of Arginine 912 and Lysine 1045. The prediction of ADMET properties from flavan-3-ol shows that the compound can be absorbed and has good permeability. Overall, the flavan-3-ol found in A. odoratissimus leaves shows the potential to be developed as a xanthine oxidase inhibitor for use in gout therapy.

Background: Moringa oleifera is a popular plant that has been known to have several importance biological activities. Objectives: To perform phytochemical analysis, to in vivo evaluate the antihyperuricemic activity and to measure the inhibition of ethanolic extract of Moringa oleifera seed on xanthine oxidase enzyme. Materials and Methods: The seed were collected from Sigi regency, Central Sulawesi, Indonesia. Extraction was performed by maceration method with ethanol 96\% as a solvent. Thin layer chromatography (TLC), high performance liquid chromatography (HPLC) and spectrophotometric UV-Vis were used to determine the phytochemical contents. The antihyperuricemic activity was evaluated by using in vivo model of rat induced by potassium oxonate. The xanthin oxidase inhibitory activity was also determined by spectroscopic method by measuring the catalytic rate of xanthin oxidase enzyme. Results: Phytochemical analysis confirmed the presence of alkaloids, terpenoids, flavonoids, phenolics, saponin and tannin. Quantitative determination of total flavonoids and quercetin concentration found the values of 82.17 {\textpm} 0.684 mg QE/g and 0.5131 {\textpm} 0.0022 mg/g dried extract, respectively. Ethanolic extract of Moringa oleifera seed have potential antihyperuricemic activity in which it can significantly reduce the serum uric acid level on potassium oxonate-induced hyperuricemic rat model with the effective dose of 125 mg/ kg BW. Xanthin oxidase inhibitory activity showed the moderate activity with IC50 of 88.39 μg/ml. Conclusion: This study confirmed the potential of Moringa oleifera seed ethanolic extract, growing in Sigi, Central Sulawesi to be developed as herbal medicinal source for antihyperuricemic drug.
