Determination of Amino Acids in Strobilanthes tonkinensis Landau Leaves by OPA-FMOC Pre-column Derivatization and RP-HPLC
The amino acids in Strobilanthes tonkinensis Landau leaves were determined by OPA-FMOC pre-column derivatization and RP-HPLC.The contents of the amino acids in the leaves under five kinds of fertilizer application were determined.The results showed the contents of the amino acids in the leaves had great difference under the five kinds of fertilizer application.The highest content of amino acids was in the bottom leaves of Strobilanthes tonkinensis Lindau with 605 organic fertilizer treatment.The study offers a scientific basis for the cultivation of Strobilanthes tonkinensis Landau and food research and development.
