标准摘要
[中文适用范围]： 该方法是用二甲基甲酰胺振摇提取，离心后，向等份上清液中加入柠檬酸铁铵和氨水，在525 nm处光谱测定所得溶液的吸光度，并测定所得溶液的吸光度。 单宁含量使用使用单宁酸制备的校准曲线。 [外文原描述]： The method consists in extraction by shaking with dimethylformamide, then after centrifuging, addition of ferric ammonium citrate and ammonia to an aliqiot part of the supernatant liquid and spectrometric determination, at 525 nm, of the absorbance of the solution thus obtained, and determing of the tannic content using a calibration curve prepared using tannic acid.
