Abstract: Phenols are the most important components for maintaining high quality of grapes. The anthocyanins and non-anthocyanin phenolic compounds in the fruit skins of Vitis ficifolia Bge and Vitis davidii Foex were extracted with methanol and ethyl acetate under the assistance of ultrasonic respectively and their composition was qualitatively and quantitatively analyzed by high performance liquid chromatography mass spectrometry (HPLC-MS). As a result, 20 anthocyanins and 6 non-anthocyanin phenolic compounds were identified in Vitis ficifolia Bge fruit skin, and 6 anthocyanins and 15 non-anthocyanin phenolic compounds in Vitis davidii Foex fruit skin. The major anthocyanins in Vitis davidii Foex fruit skin were elphinidin-3,5-O-di-glucoside and malvidin-3,5-O-di-glucoside, and in Vitis ficifolia Bge malvidin-3,5-O-di-glucoside and petunidin-3,5-O-di-glucoside. Feruloytartaric acid and its derivatives, ferulic acid hexose ester and quercetin-O-rhamnoside were the major non-anthocyanin phenolic compounds in both species of wild grapes. The content of non-anthocyanin phenolic compounds in Vitis davidii Foex was much higher than that in Vitis ficifolia Bge.
