A Comparative Analysis on Chemical Components of Volatile Oil in Plant and Fruit of Datura stramonium L

Aim To provide the basis for developing and using plant and fruit of Datura stramonium L.by analyzing chemical components of volatile oil in through comparasion.Methods The volatile oil in plant and fruit of datura stramonium L.was extracted by steam distillation.The components of volatile oil was separated and structurally identified by gas chromatography/mass spectrometry,the relative contents of the components with the peak-area normalization method in gas chromatography.Results 58 compounds have been identified from a plant and 68 from a fruit respectively.With only 19 compounds identified from a plant and a fruit.As the principal constituents of the volatile oil except 6-pentyl-5,6-dihydro-2H-pyran-2-one,other principal constituents coexist comparatively small.Conclusion There exist great differences in constituents of volatile oil in plant and fruit of datura stramonium L.and should be treated differently in use.
