Xanthine oxidase inhibitor activity of terpenoid and pyrrole compounds isolated from snake fruit (Salacca edulis Reinw.) cv. Bongkok

Abstract

The compound of 3β-hydroxy-sitosterol (1) and 2-metylester-l-H-pyrrole-4-carboxilyc acid were isolated from ethyl acetate extract of snake fruit (Salacca edulis Reinw) cv. Bongkok, (2). Inhibition of xanthine oxidase by the two compounds were evaluated against enzyme of xanthine oxidase. Compound 1 could be regarded as inactive, while compound 2 was found to be active with IC50 value of 48.86 μg mL-1. © 2007 Asian Network for Scientific Information.
