Abstract
ATTENTION has been directed by Giri, Gopalkrishnan, Radhakrishnan and Vaidyanathan1 to the high content of free hydroxyproline in the leaves of Santalum album L., and of free proline in the leaves of various species of Citrus. Their observations are of interest, as these imino-acids have previously been reported only as minor constituents of the soluble nitrogenous compounds of plant tissues, though they occur regularly as constituents of plant proteins. Hydroxyproline in particular has rarely been detected as a component of the soluble nitrogen in plant tissues.
