The isolation and identification of 5-hydroxypiperidine-2-carboxylic acid from the leaves of L. glauca Benth. by procedures using ion-exchange resins and chromatography are described. This imino acid has been synthesized and the resulting diastereo-isomers separated by chromatographic techniques. The stereochemistry of the natural and the synthetic compounds is discussed.

Infrared Absorption Spectra

A method is described for the purification of two phenazine compounds from cultures of a strain of Pseudomonas aureofaciens. The chemical properties of the compounds are described and the ultraviolet, visible, and infrared absorption spectra are shown. One compound is identified as phenazine-1-carboxylic acid and the other is probably 2-hydroxyphenazine-1-carboxylic acid.
