Abstract

Isolation on the hexane extract of the fruits of Johannesteijsmannia altifrons by vacuum liquid and radial chromatography yielded three known compounds namely β-sitosterol, γ-taraxasterol and stigmasterol. Their structures were determined using one-dimensional and two-dimensional nuclear magnetic resonance spectroscopy, fourier transform infra-red spectroscopy and mass spectrometry. All the isolated compounds were tested for their antibacterial activity using disc diffusion and minimum inhibitory concentration (MIC). All three compounds showed weak and moderate activities against all nine tested bacteria. This is the first report on the isolation of compounds from this species and on the antibacterial activity of γ-taraxasterol.
