[The problem of characterization of sterins in the gingiva by means of gas chromatography--mass spectrometry].
Methods suitable for demonstrating previously unidentifiable substances in healthy and diseased gingiva via gas chromatography/mass spectrometry were described. The advantage of these methods is that the substances can be directly demonstrated from the tissue available. The steps necessary to isolate and demonstrate the substances were explained on the basis of the phytosterol campesterol.
