ABSTRACT
Objective To extract the volatile oil of Ramulus Mori and analyze the chemical composition of the volatile oil. Methods The volatile oil of Ramulus Mori was extracted by simultaneous distillation extraction(SDE)and direct distillation extrac?tion(DDE)method,and the chemical composition was identified by GC-MS. Results Nineteen compounds were identified in the vol?atile oil extracted by SDE,which accounted for 94.49%of the total amount of detection. There were alkyl,acids,aldehydes,ketones, esters,alcohols and other substances in the volatile oil. And 16 compounds were determined in the volatile oil extracted by DDE,ac?counting for 97.12 % of the total amount detected. There were furan,carboxylic acids,esters,aldehydes,alcohols,phenols,ke?tones,alkene and acyl halide. The chemical compositions of the volatile oil extracted by SDE were more than those extracted by DDE. Conclusion The chemical constituents of volatile oil of Ramulus Mori can be more fully identified by the combination of the two ex?traction methods.
