Abstract:
In this paper, the extraction of proanthocyandins from defatted grape seeds was studied. The optimum process based on the single factor and orthogonal test was as the following： the temperature was 30℃, the concentration of ethanol 60%, pH value is 5.0, the rate of solvent to material is 20 ： 1, extraction time is 30min twice. The extraction yield is up to 96. 26% and the purity of the product is 52.64%.[著者文摘]
