Abstract

Hyperuricemia is a disease that is characterized by high uric acid levels, in which the number of victim increase year by year in the worldwide. Flavonoid is an active compound with inhibitory activity towards Xanthine Oxidase Enzyme which is a compound that plays a role in the formation of uric acid in the body. Sansevieria trifasciata is an ornamental plant which is also useful as a source of antibacterial and antioxidant agent. Studies of S. trifasciata as Xanthine Oxidase Enzyme inhibitor have not been reported. This research isolate flavonoid compounds using open column chromatography from crude extract of S. trifasciata leaves that extracted by sonication method. There are six eluent used to isolate flavonoid which are methanol : ethyl acetate, chloroform : ethyl acetate, chloroform : ethyl acetate : methanol. Wilstater test is used to select the fraction that rich of flavonoid. The best result from isolation step that contains flavonoid is assessed the inhibitory activity of xanthine oxidase. It is analyzed qualitative using Liquid Chromatography Mass Spectrometry (LCMS). The inhibition percentage showed that fraction 3 was potential to inhibit XO by 85.48 %. LC-MS chromatogram can show that crude extract and positive fraction of isolation were containing falvonoid.
