以没食子酸为对照品,采用Folin-Ciocalteu比色法测定新疆不同产地沙枣果肉及种子中总酚含量.没食子酸在2～12μg/mL范围内与吸光度呈良好线性关系(r=0.9991),平均回收率为98.80%,RSD为1.81%.7个产地沙枣种子中的总酚含最均明显高于果肉,种子总酚含量/果肉总酚含量约为3～5倍.实验方法简便、快速、准确,可用于沙枣果实的质量控制.

Gallic acid was used as a standard substance to determine total polyphenol contents in different parts of Elaeagnus angustifolia fruit growing in Xinjiang Autonomous Region by Folin-Ciocalteu method.The calibration curve of gallic acid presented good linearity within the concentration range of 2-12 μg/mL (r = 0.9991).The average of three replicates of spike recovery for total polyphenols at three levels was 98.80%,with a relative standard deviation of 1.81%.Elaeagnus angustifolia seeds exhibited significantly higher total polyphenol content than Elaeagnus angustifolia flesh,with a 3-to 5-fold increase.The method demonstrates the advantages of convenience,rapidity and accuracy,thereby providing an effective approach for the quality control of Elaeagnus angustifolia fruit.
