The chemical constituents from the fruits of Johannesteijsmannia altifrons and antibacterial activity
Noor Aziiraa Sabri1, Wan Yaacob Wan Ahmad2, Nur Shafiqa Abdullah3, Nazlina Ibrahim4.
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.
