Combined with common extraction method, and the progress of proanthocyanidins at home and abroad, the process parameters of extracting the anthocyanin from grape seed was optimized, and the best extraction method of proanthocyanidins from grape seeds was get. The paper was expected to provide scientific basis for industrialized production and comprehensive utilization of proanthocyanidins from grape seed, so as to the  proanthocyanidins has a wider application.
