The chemical constituents of the volatile compounds of Cornus officinalis Sieb. et Zucc were extracted by steam distillation and analyzed by GC-MS, meanwhile their relative contents were determined by peak area normalization method and 2-Octanol was used to calculate the quantity of each components. 50 compounds were separated and 47 of them were identified and determined, amounting to 93.7% of the total area of the peaks. The searching result indicated that the principal constituents in the volatiles were 4-HydroxyBenzeneethanol, Glutaconic-anhydride, Benzothiazole, Methyl 2-hydro- xybenzonate, Undecanoic acid, 3-Furaldehyde, p-Menth-1-en-8-ol, (Z)-Hex-3-en-1-ol, Linalool, 4-Pentenal. The result revealed the relative aroma characteristics in the fruits of Cornus officinalis Sieb. et Zucc.
