Alkaloids in whole plant material: direct analysis by kinetic energy spectrometry.

摘要: A new approach to mixture analysis has been applied the direct detection of various alkaloids in plant materials. The method requires absolutely no sample treatment. Results are presented for cocaine, morphine, papaverine, coniine, and atropine. signal-to-background characteristics superior those conventional mass spectrometry. Sensitivity is sufficient detect identify between 1 10 nanograms alkaloid.
