A metal component absorption enhancer which enhances the absorption of at least one metal component selected from the elements belonging to groups 2 to 12 in the third to fourth periods when a plant grows. The metal component absorption enhancer contains 5-aminolevulinic acid or a derivative thereof represented by the following general formula (1), or a salt thereof as an active ingredient:RRNCHCOCHCHCOR&#x2003;&#x2003;(1) wherein Rand Reach independently represents a hydrogen atom, an alkyl group, an acyl group, an alkoxycarbonyl group, an aryl group, or an aralkyl group; Rrepresents a hydroxyl group, an alkoxy group, an acyloxy group, an alkoxycarbonyloxy group, an aryloxy group, an aralkyloxy group, or an amino group, and is used for performing a treatment with 0.001 to 20 ppm of the 5-aminolevulinic acid, the derivative thereof, or the salt thereof per each time.

Metal component absorption enhancer in plant

A 5-aminolevulinic acid salt which is useful in fields of microorganisms, fermentation, animals, medicaments, plants and the like; a process for producing the same; a medical composition comprising the same; and a plant activator composition comprising the same.

5-aminolevulinic acid salt, process for producing the same and use thereof

To provide a production method of phosphates of amino acids, typified by &#x3b4;-aminolevulinic acid phosphate, or esters thereof. A method for producing phosphates of an amino acid or an ester thereof, which comprises allowing an amino acid, an ester thereof or a salt thereof to coexist with phosphoric acids and a basic nitrogen-containing compound.

Method for producing amino acid phosphates

To provide a novel crystal of 5-aminolevulinic acid phosphate having a high thermal stability, a high melting point, and an excellent moisture absorption resistance as well as a process for producing the same. A crystal of 5-aminolevulinic acid phosphate, which shows characteristic peaks at 7.9&#xb0;&#xb1;0.2&#xb0;, 15.8&#xb0;&#xb1;0.2&#xb0;, 18.9&#xb0;&#xb1;0.2&#xb0;, 20.7&#xb0;&#xb1;0.2&#xb0;, 21.1&#xb0;&#xb1;0.2&#xb0;, 21.4&#xb0;&#xb1;0.2&#xb0;, 22.9&#xb0;&#xb1;0.2&#xb0;, 33.1&#xb0;&#xb1;0.2&#xb0;, and 34.8&#xb1;0.2&#xb0; as diffraction angles 2&#x3b8; in a powder X-ray diffraction, and a process for producing the same.
