This paper reiviewed the current situation of quality control of grape seed extract in domestic and international market. Considering the fact that there is no national or industrial technical specifications established for the extract product, the authors suggested that two sets of quality specifications should be established for the grape seed extract. The two sets of specifications are: the high purity grape seed extract should contain polyphenol NLT 95%, monomer NLT 10%; and the grape seed extract with ordinary quality should have a procyanidolic value NLT 95, and monomer NLT 6%.
