title: High-resolution gas chromatography/mass spectrometric analysis of tobacco and marijuana sterols.
abstract: Components of the sterol fraction of tobacco and marijauna were resolved as trimethylsilyl derivatives by gas chromatography with glass capillary columns. Ten phytosterols in tobacco and five in marijuana were identified by comparisons of their retention with authentic compounds on three different stationary phases and through mass-spectral data.
