Analysis of Amino Acids of Pterula umbrinella Bres.

Abstract

Abstract: The analysis of amino acids in Pterula umbrinella Bres. was made with reversed-phase high performance liquidchromatography,using phenylisothiocyanate as a precolum derivatizing agent(i.e.pico-Tag method).The results showed that kindsof amino acid(included kinds of essential amino acids)existed in Pterula umbrinella Bres.,except that tryptophane destroyed byhydrolysis is not checked out. The sum of amino acids was 179.652μg/mg. The sum of essential amino acids was 63.546μg/mg.The percentage of essential amino acids was 35.37%.The results provide reference for exploitation of Pterula umbrinella Bres.resources.

Key words: Pterula umbrinella Bres, amino acids, reversed-phase high performance liquid chromatography, PICO-TAG
