The volatile oil was extracted from the Jasminum nudiflorum Lindl by steam distillation and use beta-cyclodextrin to wrap the volatile oil. The gas chromatography-mass spectrometry( GC/MS) techniques for beta cyclodextrin wrap in the Jasminum nudiflorum Lindl volatile oil before and after chemical composition were analyzed. The results showed that the main components of the volatile oil in the Jasminum nudiflorum Lindl beta cyclodextrin wrap befor were: aldehydes accounted for 71.26%,alcohols were 15.62% and 2-pentyl furan 2.78%.wrap after the main components of the volatile oil: aldehyde of 10( 52.63%),alcohol( 26.43%),2-amyl furan,celeryene accounted for 5.54%,2.05% formic acid octyl ester( 1.70%),its main chemical composition is a slight change of aldehydes and alcohols,but there is no fundamental change.Because of the special structure of beta-cyclodextrin,it becomes a white powdered solid after the volatile oil is encapsulated,which is convenient for transportation and preservation.The volatile oil has been added to the stability of light and heat,reducing the volatility.
