摘要

[Objectives]The contents of seven components(gallinic acid,epicatechin,catechin,ferulic acid,chlorogenic acid,rutin,and caffeic acid)in Vidal blanc grape were determined.[Methods]The L 9(3 4)orthogonal design method was used to optimize the extraction process.High performance liquid chromatography(HPLC)was used to determine gallic acid,epicatechin,catechin,ferulic acid,chlorogenic acid,rutin and caffeic acid in Vidal blanc grape.[Results]The contents of gallic acid,epicatechin,catechin,ferulic acid,chlorogenic acid,rutin and caffeic acid in Vidal blanc grape were 155 1μg/g,20.55 mg/g,77.11 mg/g,0.738 8,0.910 0,164.5 and 175.8μg/g,respectively.[Conclusions]HPLC method for the determination of the contents of seven components in the Vidal blanc grape can better control the quality of the variety.
