Abstract

The non‐volatile organic acids are extracted from grass and separated from amino‐acids, sugars, etc., by ion‐exchange chromatography. The acid‐containing fractions displaced from the anion‐exchange columns are further separated by partition chromatography on buffered silica gel.

One of the acids present is proved to be quinic acid. By means of filter‐paper chromatography, the presence of succinic, malic, malonic, and citric acids is indicated, thus confirming earlier work. Chlorogenic acid, not previously reported in grass, was also shown to be present. At least two other acids, whose identities are not established, are present, one of which appears to be allied constitutionally to quinic acid.
