A new determination of esterases and arylesterases (E. C. 3.1.1.2.) with 4-nitrophenylacetate is described. The results are compared with those of the method described by Pilz using phenylacetate. 4-nitrophenylacetate instead of phenylacetate allows a kinetic reaction. The precision of the determination is good, the method easy to handle. Normal values: 1100--2600 U/1 (total esterases), 700--2100 U/1 (arylesterases) at +25 degrees C.
本文描述了一种用4-硝基苯乙酸酯对酯酶和芳基酯酶（E.C.3.1.1.2.）进行新的测定方法。将结果与皮尔兹使用苯乙酸酯所描述的方法的结果进行了比较。用4-硝基苯乙酸酯代替苯乙酸酯可实现动力学反应。该测定方法精度良好，易于操作。正常数值：在25摄氏度时，总酯酶为1100 - 2600 U/1，芳基酯酶为700 - 2100 U/1。
