摘　　要：以没食子酸为标准品采用福林(Folin-Ciocaileu)法测定红枣汁中总酚含量,标准曲线的回归方程为:y=0.1136x+0.0054(R2=0.9993)。对其稳定性、精密度、重复性、加样回收率进行了试验,相对标准偏差(RSD)在0.1%～0.71%范围内。Gallic acid was used as the standard, total polyphenols of Chinese jujube juice were determined by Folin-Ciocaileu method. Regressive equation of standard curve is y=0.113 6x＋0.005 4 （R^2=0.999 3）. Stability, precision, repetition and recovery rate were determined, relative standard deviation （RSD） is 0.1%-0.71%.
