Abstract:
Objective: To clarify chemical dynamic change of volatile oil of Root of Changium Smyrnioides Wolff during Processing, to analyse and study the change of constituent proportion to see if new constituents produce or original constituents disappear, to discuss the processing mechanism of root of Changium smyrnioides . Method: The constituents and contain of volatile oils of root of Changium smyrnioides before, during and after processing are comparatively analyzed by using techniques of combined capillary gas chromatography mass spectrometry computer. Result: 34 chemical compounds are identified, among them there were 29 compounds isolated from volatile oil of fresh root of Changium smyrnioides, with a proportion of 97.873% in total oil, its main constituent is CSY and its content reaches 70.946%; 34 compounds were isolated from volatile oil of fresh decorticated root of Changium smyrnioides, with a propoction of 93.452%, main constituent is CSY, its content reaches 75.909%; and 19 compounds from volatile oil of fresh root cortices of Changium smyrnioides, 96.878% , main constituent is CSY, content 70.977%; 11 compounds from volatile oil of processed root of Changium smyrnioides, 88.839%, main constituent is CSY, content 67.234%. Conclusion: Main reasons of non sensibilization of processed root of Changium smyrnioides are considered to be the content decrease and qualitative change of the volatile oils, and the content of snsibilization activity constituent——CSY decreased from 0.0497% to 0.0134%.
