In this study, the Wild grape (Vitis amurensis Rupr) which was supplied by a local wine factory of Zhangjiakou City, Hebei Province was analyzed for the volatile compounds in the skin. The volatile flavor compounds were extracted by using the method of simultaneous distillation extraction (SDE) and then analyzed by gas chromatography‐mass spectrometry (GC‐MS) with phenylacetate as the internal standard. Generally the volatile compounds of the wild grape are quite complicated. The analytical results showed that 65 kinds of volatile compounds mostly consisting of 12 esters compounds (2.94 mg/kg), 11 aldehydes compounds (39.96 mg/kg), 14 terpenes compound (4.97 mg/kg), 4 ketone compounds (0.44 mg/kg), 4 phenols compounds (1.33 mg/kg) 7 eneyne compounds (7.69 mg/kg) , 1 alcohol (2.37 mg/kg), 5 heterocycle compounds(1.11 mg/kg) ,5 acid compounds(10.94 mg/kg) and 2 amide compounds (3.47 mg/kg) were detected. The total content of these bioactives is 75.22 mg/kg, in which aldehyde compounds account for the most proportion. Fourteen terpenes were found and the kinds were the most among all of the bioactive compounds; also, they were the main aroma compounds in the wild grape skin.
