The non-volatile acids of the dried apricot consist of a mixture of l-malic acid and citric acid, in the proportion of about .25 to 10, with traces of an unidentified acid which may be oxalic acid. A new alkaloid has been isolated from Lupinus spathulatus, a plant that occurs in Utah and Colorado. The new base has been named spathulatine and has been assigned the formula C33H64O5N4. The properties of the free alkaloid and the preparation of its mercuric iodide compound which may serve as a microchemical test are described.
