✦ Synopsis

A method for the quantitative determination of arginase in plant material is presented. The alkaloid and arginase content of Datum tatula L. was determined for various parts of the plant at various ages. T h e quantitative alkaloid-enzyme relationship tends to support the theory that the first step in the biosynthesis of the tropinone alkaloids is the hydrolytic action of arginase on plant protein molecules containing arginine.

VIDENCES in the literature whkh can be used to relate alkaloid biosynthesis to enzymically catalyzed reactions are meager.
