RESUMEN
In this study, antimicrobial and antioxidant activities of the hexane extract of the root of Ventilago madraspatana were evaluated. Based on the significant bioactivity of crude hexane extract, an active compound was purified from the root extract. The active compound was further purified and identified as aromodendrin-4'-methyl ether by the (1)H NMR spectrum. The isolated compound significantly inhibited Staphylococcus epidermidis with the lowest MIC and MBC at 78 µg/mL (P < 0.05). The compound also exhibited significant anticandidal activity with MIC and MBC values of 312 and 625 µg/mL, respectively. The radical scavenging activity of aromodendrin-4'-methyl ether was evident by its lower IC50 values of 60 µg/mL for DPPH scavenging and 3.2 µg/mL for ABTS scavenging. The compound also exhibited ferrous ion chelation and H2O2 scavenging activities. The study is an attempt to increase the industrial utility of V. madrasapatana.
