Über das Vorkommen von Pyridinderivaten im normalen Harn.

Abstract

The authors isolated trigonelline in pure form from various normal urines, thus further reducing urinary N of unknown origin. They consider that the gynesin found by Kutscher in all probability is trigonelline; and they have substantiated Kutscher''s report of methyl-pyridinium hydroxide in normal urine.
