Abstract

Novel method for the determination of .alpha.-amylase which method comprises contacting a sample suspected of containing .alpha.-amylase with a starch derivative carrying a substituent capable of dyestuff-forming coupling; separating from the resulting starch-containing phase the low molecular weight soluble fission products formed by splitting of said starch derivative by .alpha.-amylase; coupling the said couplable substituent with another dyestuff forming component; and measuring the dyestuff so formed as a measure of the initial .alpha.-amylase content.
